nasapower aims to make it quick and easy to automate downloading of the 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 with varying spatial resolutions dependent on the original data and with several temporal resolutions depending on the POWER parameter and community.
Note that the data are not static and may be replaced with improved data. Please see https://power.larc.nasa.gov/docs/services/ for detailed information in this regard.
Quick start
nasapower can easily be installed using the following code.
From GitHub for the version in-development
A development version is available through GitHub.
if (!require("remotes")) {
install.packages("remotes")
}
remotes::install_github("ropensci/nasapower")Example
Fetch daily “ag” community temperature, relative humidity and precipitation for January 1, 1985 for Kingsthorpe, Queensland, Australia.

lonlat = c(151.81, -27.48),
pars = c("RH2M", "T2M", "PRECTOTCORR"),
dates = "1985-01-01",
temporal_api = "daily"
)
