How to open grib file in R?

3 messages · Jeff Newmiller, Jonsson

I have this   https://echange-fichiers.inra.fr/get?k=6TdTdezNeZwAqJtpwVm    
grib file which is a regular lat-lon 0.25x0.25 degrees and contains 4 fields
. 
I tried to open it using :
  grib <-
readGDAL("C:\\Users\\aalyaari\\Desktop\\Vol_025_H14_2010060700.grib") 

but I got this error:
C:\Users\aalyaari\Desktop\Vol_025_H14_2010060700.grib has GDAL driver GRIB 
and has 721 rows and 1440 columns Error in validityMethod(as(object,
superClass)) : 
  Geographical CRS given to non-conformant data: -90.125  90.125

Any idea why I am getting this error?

Your question should have been posted to the R-sig-geo mailing list.

FWIW I have no direct experience with the files or functions you are using, but I have to say the error message seems pretty clear to me: latitude values are normally limited to [-90,90], but your file appears to have data outside this range. Thus, the file appears to have invalid data.
