List of Figures:
Figure 1.(a), ( b) and (c ): Horizontal decoupling test in clear sky condition. This test shows the sensitivity of 2m temperature (b) and relative humidity (c) to a well known initial perturbation box of mean soil moisture content Wp (a). |
Figure 2.(a), (
b) and (c
): Same as Figure 1 for a box placed near to the north-eastern side of the
domain (meteorological perturbed conditions). |
