| Name: | Snow depth water equivalent | Abbreviation: | sd | Unit: | kg m-2 | paramId: | 228141 |
S2S details
| Definition | The parameter expresses the Snow depth in kg of snow over one square meter. The unit corresponds to 1 mm of water equivalent. |
| Validity | Daily averaged |
| Comment | Please note that there exists a parameter Snow depth in GRIB 2 (Parameter number 11), which has the unit m (not m of water equivalent). This parameter measures the "real height" of snow cover. Computed from instantaneous values at 00Z, 06Z, 12Z and 18Z |
