Sample file | MARS | Sample file | parameter ( WMO GRIB2 - TABLE 4.2-10-0) | Discipline | Category | Number | Horizontal grid | Vertical level | time (grib2/tables/2/4.4.table) | Description |
---|---|---|---|---|---|---|---|---|---|---|
WAVE_165.128_1x1.grib | 165.128 | WAVE_165.128_1x1.grb2 | U-component of wind ( 10 m ) | 0 [ M products ] | 2 [ Momentum ] | 2 |
. regular lat-long grid . grid spacing free for the contributor to chose . not need to be global eg: gridDefinitionTemplateNumber = 0 [Latitude/longitude] | I think I should use : 102 Specific altitude above mean sea level in section 4. What is your view ? |
