GSODR 3.1.10

CRAN release: 2024-02-05

Minor changes

  • Use {roxyglobals} for handling global values.

  • Update internal isd history database.

  • Tidy up Appendix 2 in vignette, map of GSOD station locations. Add a caption and remove text from .png image itself.

Bug fixes

  • Fix codecov badge in README

GSODR 3.1.9

CRAN release: 2023-08-22

Bug fixes

  • Fix duplicated elevation columns.

Minor changes

  • Remove {httr} as an Import. Use base functionality to check existence first and then {curl} will properly error if a download fails, we will use that functionality.

  • Fix codecov badge to point at proper branch.

  • Ensure function titles are all proper title case.

  • Enhanced handling of data requests for incompatible station-year combinations. A warning() is issued for each bad combo, but if a vector() of stations is requested, any valid stations will still be downloaded with the bad combos omitted after the warning is emitted.

GSODR 3.1.8

CRAN release: 2023-02-25

  • Update CITATION file to follow CRAN’s ~ever-changing whims~ guidelines.

GSODR 3.1.7

CRAN release: 2023-01-05

Bug fixes

  • Fix bug where the isd_history.Rda data object was not updated using the data_raw/fetch_isd-history.Rmd.

  • Fix bug where stations were not available in the internal isd_history file, this caused NA values to appear for some stations when run using format_GSOD() or to not be available for download with get_GSOD(). This adds 1,334 new stations that are now available through GSODR. These were always available through GSOD but this bug prevented them from being accessed through this package.

  • Fix minor bug where get_inventory() returned garbage in the header of the object.

GSODR 3.1.6

CRAN release: 2022-08-13

Minor changes

  • Redoc package to correct HTML issues.

  • Update internal isd-history database.

  • Update changed URLs.

  • Updates invalid URLs.

GSODR 3.1.4

CRAN release: 2021-10-07

Minor changes

  • Skip ANY and ALL tests on CRAN. This fixes the “problems” with GSODR failing on a Solaris instance when the server failed to respond.

  • Update internal isd-history database.

  • Use \CRANpkg{} in place of \pkg{} in documentation.

GSODR 3.1.2

CRAN release: 2021-07-04

Bug fixes

  • Fix (more) bugs related to NA value replacements.

Minor changes and improvements

  • Simplify NA value replacement in “PRCP” column.

  • The PRCP column values are rounded to two decimal places as in original GSOD data, not one.


  • Better tests for the generated weather data data.table output checking values and formats.

  • Tests are updated for updated data availability in the GSOD data due to continuous improvements to the data set.

  • Standardise handling of author/contributor comments. None have a full stop now in the comment.

  • Use on.exit() to reset the working directory to the original user-space value after changing the working directory to untar files located in tempdir().

GSODR 3.1.1

CRAN release: 2021-06-25

Bug fixes

  • Fixes bug reported in #84 in the FRSHTT columns where the values were all reported as NA even if there were observed values.

  • Fixes bug where NA values reported as 99.99, 999.9 or 9999.9 were not replaced with NA.

  • Fix bug where FRSHTT (Fog, Rain/Drizzle, Snow/Ice, Hail, Tornado, Thunder) column values split into the respective columns only returned NA, not the proper values as expected. Reported in #84.

Minor changes

  • Examples are no longer wrapped in \donttest{} but use @examplesIf interactive() instead.

GSODR 3.1.0

CRAN release: 2021-03-21

New features

  • Include columns for COUNTRY_NAME (country name in English), ISO2C and ISO3C in the final output from get_GSOD() and reformat_GSOD().

  • Diffs in the isd_history are now recorded in the /data-raw/ file and shipped with GSODR as isd_history.rda, which can be viewed by using load(system.file("extdata", "isd_diff.rda", package = "GSODR")).

  • Update and improve documentation to reflect country name and ISO code columns.

Minor improvements

  • Update NCEI data usage statement.

GSODR 3.0.0

CRAN release: 2021-01-24

Breaking changes

  • Remove parallel processing functionality. A bug that I was unable to properly debug with future.apply::future_lapply() caused the get_GSOD() and reformat_GSOD() functions to run without completing or responding was fixed by simply using R’s base lapply() function. If parallel processing is needed, users should implement their own solutions to download and process in parallel.

Bug fixes

  • Fix bug that caused the package to run without responding.

  • Fix test that failed on CRAN’s Solaris server for some reason.

  • Removes a working DOI link from the reference for the equation used because win-builder checks say it doesn’t work (even though it does and there’s nothing wrong with the link any time I check).

GSODR 2.1.2

CRAN release: 2020-09-20

Bug fixes

  • Fix bug where nearest_stations() did not always return the nearest station as the first value in the vector

Minor changes

CRAN release: 2020-04-17

Major changes

  • Implement new calculations for EA, ES and RH using improved August-Roche-Magnus approximation (Alduchov & Eskridge 1996). HT Rich Iannone for his use in stationaRy. This will result in different EA, ES and RH calculations from the prior versions of GSODR. However, this new implementation should be more accurate as discussed in (Alduchov & Eskridge 1996).

Alduchov, O.A. and Eskridge, R.E., 1996. Improved Magnus form approximation of saturation vapor pressure. Journal of Applied Meteorology and Climatology, 35(4), pp.601-609.

Minor changes

  • Update internal station list to latest

  • Update internal station list to latest

  • Tidy up documentation, mainly fix functions’ title capitalisation

  • get_GSOD() checks the number of stations being requested. If the number is >10, the entire annual file will be downloaded and requested stations will then be selected and returned. This saves time by reducing the number of requests made to the server. Users should not see any difference other than quicker responses for a large number of requested stations.

Major changes

  • Requires R >= 3.5.0 due to the storage of .Rds files using the latest version

Major changes

  • Data for station locations and unique identifiers is now provided with the package on installation. Previously this was fetched each time from the ftp server.

  • The station metadata can now be updated if necessary by using update_station_list(), this change overwrites the internal data that were originally distributed with the package. This operation will fetch the latest list of stations and corresponding information from the NCEI ftp server. Any changes will be overwritten when the R package is updated, however, the package update should have the same or newer data included, so this should not be an issue.

  • Replace plyr functions with purrr, plyr is no longer actively developed

  • plyr is no longer an import

Minor changes

  • Fix bugs in the vignettes related to formatting and spelling

  • A new function, nearest_stations() is now included to find stations within a user specified radius (in kilometres) of a point given as latitude and longitude in decimal degrees

  • A general use vignette is now included

  • New vignette with a detailed use-case

  • Output files now include fields for State (US only) and Call (International Civil Aviation Organization (ICAO) Airport Code)

  • Use FIPS codes in place of ISO3c for file name and in output files because some stations do not have an ISO country code

  • Spatial file output is now in GeoPackage format (GPKG). This results in a single file output unlike shapefile and allows for long field names

  • Users can specify file name of output

  • R >= 3.2.0 now required

  • Field names in output files use “_” in place of “.”

  • Long field names now used in file outputs

  • Country is specified using FIPS codes in file name and output file contents due to stations occurring in some locales that lack ISO 3166 3 letter country codes

  • The get_GSOD() function will retrieve the latest station data from NCDC and automatically merge it with the CGIAR-CSI SRTM elevation values provided by this package. Previously, the package provided it’s own list of station information, which was difficult to keep up-to-date

  • A new reformat_GSOD() function reformats station files in “WMO-WBAN-YYYY.op.gz” format that have been downloaded from the United States National Climatic Data Center’s (NCDC) FTP server.

  • A new function, get_station_list() allows for fetching latest station list from the FTP server and querying by the user for a specified station or location.

  • New data layers are provided through a separate package, GSODRdata, which provide climate data formatted for use with GSODR.

    • CHELSA (climatic surfaces at 1 km resolution),

    • MODCF * Remotely sensed high-resolution global cloud dynamics for predicting ecosystem and biodiversity distributions,

    • ESACCI * ESA’s CCI-LC snow cover probability and

  • All files are downloaded from server and then locally processed, previously these were sequentially downloaded by year and then processed

  • A progress bar is now shown when processing files locally after downloading

  • Reduced package dependencies

  • The get_GSOD() function now checks stations to see if the years being queried are provided and returns a message alerting user if the station and years requested are not available

  • When stations are specified for retrieval using the station = "" parameter, the get_GSOD() function now checks to see if the file exists on the server, if it does not, a message is returned and all other stations that have files are processed and returned in output

  • Documentation has been improved throughout package

  • Better testing of internal functions

Bug Fixes

  • Fixed: Remove redundant code in get_GSOD() function

  • Fixed: The stations data frame distributed with the package now include stations that are located above 60 latitude and below -60 latitude

Deprecated and defunct

  • Missing values are reported as NA for use in R, not -9999 as previously

  • The path parameter is now instead called dsn to be more inline with other tools like readOGR() and writeOGR()

  • Shapefile file out is no longer supported. Use GeoPackage (GPKG) instead

  • The option to remove stations with too many missing days is now optional, it now defaults to including all stations, the user must specify how many missing stations to check for an exclude

  • The max_missing parameter is now user set, defaults to no check, return all stations regardless of missing days

GSODR 0.1.9

CRAN release: 2016-07-15

Minor changes

  • Users can now select to merge output for station queries across multiple years. Previously one year = one file per station. Now are set by user, merge_station_years = TRUE parameter, only one output file is generated

  • Country list is now included in the package to reduce run time necessary when querying for a specific country. However, this means any time that the country-list.txt file is updated, this package needs to be updated as well

  • Updated stations list with latest version from NCDC published 12-07-2016

  • Country list is now included in the package to reduce run time necessary when querying for a specific country. However, this means any time that the country-list.txt file is updated, this package needs to be updated as well

  • Country level, agroclimatology and global data query conversions and calculations are processed in parallel now to reduce runtime

  • Improved documentation with spelling fixes, clarification and updates

  • Enable ByteCompile option upon installation for small increase in speed

  • Fix bug with connection timing out for single station queries.

  • Somehow the previously working function that checked country names broke with the toupper() function. A new function from juba fixes this issue and users can now select country again

  • User entered values for a single station are now checked against actual station values for validity

  • stations.rda is compressed

  • stations.rda now includes a field for “corrected” elevation using hole-filled SRTM data from Jarvis et al. 2008, see for a description

  • Set NA or missing values in CSV or shapefile to -9999 from -9999.99 to align with other data sources such as WorldClim

Minor changes

  • Documentation is more complete and easier to use

GSODR 0.1.7

CRAN release: 2016-06-02

Bug Fixes

  • Fix issues with MIN/MAX where MIN referred to MAX (Issue 5)

  • Spelling corrections

Major changes

  • Include MIN/MAX flag column

  • Station data is now included in package rather than downloading from NCDC every time get_GSOD() is run, this data has some corrections where stations with missing LAT/LON values or elevation are omitted, this is not the original complete station list provided by NCDC.

GSODR 0.1.5

CRAN release: 2016-05-17

Bug Fixes

  • Fixed bug where YDAY not correctly calculated and reported in CSV file

  • CSV files for station only queries now are names with the Station Identifier. Previously named same as global data

  • Likewise, CSV files for agroclimatology now are names with the Station Identifier. Previously named same as global data.

Minor Changes

  • Set values where MIN > MAX to NA

  • Set more MIN/MAX/DEWP values to NA. GSOD README indicates that 999 indicates missing values in these columns, this does not appear to always be true. There are instances where 99 is the value recorded for missing data. While 99F is possible, the vast majority of these recorded values are missing data, thus the function now converts them to NA

GSODR 0.1.4

CRAN release: 2016-05-09

Bug Fixes

  • Fixed bug related to MIN/MAX columns when agroclimatology or all stations are selected where flags were not removed properly from numeric values.

Minor Changes

  • Set NA to -9999.99

GSODR 0.1.2

Bug Fixes

  • Bug fix in importing isd-history.csv file. Previous issues caused all lat/lon/elev values to be >0.

  • Bug fix where WDSP was mistyped as WDPS causing the creation of a new column, rather than the conversion of the existing

  • Bug fix if Agroclimatology selected. Previously this resulted in no records.

  • Set the default encoding to UTF8.

  • Bug fix for country selection. Some countries did not return proper ISO code.

  • Bug fix where WDSP was mistyped as WDPS causing the creation of a new column, rather than the conversion of the existing

  • Use write.csv, not readr::write_csv due to issue converting double to string:

GSODR 0.1.1

CRAN release: 2016-04-20

Major changes

  • Now available on CRAN

  • Add single quotes around possibly misspelled words and spell out comma-separated values and geographic information system rather than just using “CSV” or “GIS” in DESCRIPTION.
