Can R read grib file(when it is not raster) and convert it to ASCII file?

问题

I am trying to read this grib file but I got an error.is there a way we can solve this problem

    grib <- readGDAL("C:\\file.grib") 

Error in .local(.Object, ...) : 
  grib is a grib file, but no raster dataset was successfully identified.

回答1:

it is not an R problem.

using gdal, I have this :

gdalinfo --debug on H14_2011010400.grib 

GRIB: Undefined parameter table (center 98-0 table 228).
GRIB: Undefined parameter table (center 98-0 table 228).

GRIB: Problems with ReadGrib1Record called by ReadGrib2Record
Inside ReadGrib1Record
GRIB1 GDS: Expect PV = 255 != 33

ERROR 4: H14_2011010400.grib is a grib file, but no raster dataset was successfully identified.
gdalinfo failed - unable to open 'H14_2011010400.grib'.

I think that your grib file is wrongly encoded, tryu to install wgrib to get more info.
