A New Land Surface Hydrology within the Noah-WRF Land-Atmosphere Mesoscale Model Applied to Semiarid Environment: Evaluation over the Dantiandou Kori (Niger)

Figure 2

Domain average comparison between simulated and observed precipitation over Dantiandou Kori: (a) the cumulated annual precipitation rate (mm) simulated by each experiment; (b) the ratio to annual precipitation of daily precipitation simulated by each experiment but not observed, expressed in %, distinctions are made for precipitations that are simulated before, during and after the observed monsoon season; (c) the times series of simulated and observed monthly and daily precipitations (mm/day). The observations are in black, CTL in blue and PHY in red. The daily biases, the root mean square errors (RMSE) and the correlations (r) are also given for each experiment.

(a) 2 years cumulated precipitations.

(b) The amount of annual precipitation simulated but not observed.

(c) Time series of daily and monthly precipitations (mm/day).
