on this open FTP server (ftp://ftpdatos.aemet.es/modelos_numericos/hirlam005_peninsula/) you can find HIRLAM models from the Spanish meteorological service.
The documentation in the LEEME files (in spanish) says the data files are in GRIB-1 format. Unfortunally I'm unable to read it. I use differet programs, like QGIS, and commaind line tools: wgrid, grid_ls, etc without success.
Anyone can take a look and let me know how read it.
I'm new to grib and I dont understand about the codes and keys. The documentation at ftp://ftpdatos.aemet.es/modelos_numericos/hirlam005_peninsula/LEEME_DATOS.txt talks about IPAR, LTYP and LEV ids.
Also it contains some description about the parameters in the files:
Variable || Unidad || IPAR || LTYP || LEV Temperatura a 2m K 011 105 2 Componente x del viento a 10m m/s 033 105 10 Componente y del viento a 10m m/s 034 105 10 Precipitación total kg/m2 061 105 0 Humedad relativa a 2m kg/kg 052 105 2
Can someone help me reading that data ?
=== UPDATED ===
I finally found the problem which was that I was downloading files in ASCII mode instead BINARY.
I can confirm the grib_api tool, once compiled and installed works perfectly. Example:
$ grib_ls 20120220000000_sfc_fc15 20120220000000_sfc_fc15 edition centre typeOfLevel level dataDate stepRange shortName packingType gridType 1 lemm heightAboveGround 2 20120220 15 2t grid_second_order_SPD1 rotated_ll 1 lemm heightAboveGround 10 20120220 15 10u grid_second_order_SPD1 rotated_ll 1 lemm heightAboveGround 10 20120220 15 10v grid_second_order_SPD1 rotated_ll 1 lemm heightAboveGround 2 20120220 15 r grid_second_order_SPD1 rotated_ll 1 lemm heightAboveGround 0 20120220 0-15 unknown grid_second_order_SPD1 rotated_ll 5 of 5 grib messages in 20120220000000_sfc_fc15 5 of 5 total grib messages in 1 files
On the other hand, I'm not able to make work gdalinfo with this GRIB files, but for the moment I don't require it.
