The parameter 236 (Soil temperature level 4) specifies that its top level is 100cm and its bottom level is 289cm so to encode this information in GRIB edition 1 we would need to set the value of the key "bottomLevel" to 289 (octet 12 in section 1. See GRIB edition 1 section 1 spec) |
The parameter 236 (Soil temperature level 4) specifies that its top level is 100 cm and its bottom level is 289 cm so to encode this information in GRIB edition 1 (GRIB1) we would need to set the value of the key "bottomLevel" to 289 (octet 12 in section 1. See GRIB1 section 1 spec).
Note for this parameter, the key "indicatorOfTypeOfLevel" is 112 which means "Layer between two depths below land surface" (See Code Table 3).
In this case, we allocate octet 11 for the "topLevel" key and octet 12 for the "bottomLevel" key.
