nasapower aims to make it quick and easy to automate downloading NASA-POWER global meteorology, surface solar energy and climatology data in your R session as a tidy data frame
tibble object for analysis and use in modelling or other purposes. POWER (Prediction Of Worldwide Energy Resource) data are freely available for download at a resolution of 1/2 arc degree longitude by 1/2 arc degree latitude.
Please see https://power.larc.nasa.gov/ for more on the data and other ways to access it and other forms of data available, e.g., your web browser or an ESRI REST API.
nasapower can easily be installed using the following code.
The stable version is available through CRAN.
