| Jörg Urban | ECMWFs has four soil layers: layer 1 from 0cm to 7cm, layer 2 from 7cm to 28cm, layer 3 from 28cm to 1m and layer 4 from 1m to 2.89m. The parameter soil temperature is then computed:
st = ( 7 * T_1 + 13 * T_2 )/20,
where T_i are the averaged soil temperatures on the i-th level. |   |
