nasapower: NASA POWER API Client 
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 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 CRAN
The stable version is available through CRAN.
install.packages("nasapower")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.

daily_ag <- get_power(community = "ag",
lonlat = c(151.81, -27.48),
pars = c("RH2M", "T2M", "PRECTOTCORR"),
dates = "1985-01-01",
temporal_api = "daily"
)
