Download meteorological and atmospheric data
Description
The download_merra2() function accesses and downloads various
meteorological and atmospheric collections from NASA's Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) model.

)
Arguments
collection
character(1). MERRA-2 data collection file name.
date
character(1 or 2). length of 10. Date or start/end dates for downloading data.
Format "YYYY-MM-DD" (ex. January 1, 2018 = "2018-01-01").
directory_to_save
character(1). Directory to save data.
acknowledgement
logical(1). By setting TRUE the
user acknowledges that the data downloaded using this function may be very
large and use lots of machine storage and memory.
download
logical(1). FALSE will generate a *.txt file
containing all download commands. By setting TRUE the function
will download all of the requested data files.
remove_command
logical(1).
Remove (TRUE) or keep (FALSE).
hash
logical(1). By setting TRUE the function will return
an rlang::hash_file() hash character corresponding to the
downloaded files. Default is FALSE.
the text file containing download commands.
Value
For hash = FALSE, NULL
For hash = TRUE, an rlang::hash_file character.
netCDF (.nc4) files will be stored in a
collection-specific folder within directory_to_save.
