Get MERRA-2 grid IDs closest to the given coordinates
closest_locid(lon, lat, asList = FALSE)longitude in degrees (-180 <= lon <= 180)
latitude in degrees (-90 <= lat <= 90)
integer vector with locations IDs (locid) when `asList` is FALSE (default). In the case of several values, only the first `locid` will be returned. If `asList` is TRUE, a list is returned with possible multiple values for each coordinate.

#> The legacy packages maptools, rgdal, and rgeos, underpinning the sp package,

#> It may be desirable to make the sf package available;
#> package maintainers should consider adding sf to Suggests:.
#> The sp package is now running under evolution status 2
