Soil Moisture Assimilation Using a Modified Ensemble Transform Kalman Filter Based on Station Observations in the Hai River Basin

Table 2

The time-mean values of observed and interpolated forcing data, as well as the corresponding time-mean RMSEs: near-surface air temperature, relative humidity, wind speed, precipitation, downward shortwave radiation, and longwave radiation.

	Near-surface air temperature (K)	Relative humidity (Kg/Kg)	Surface pressure (Pa)	Wind speed (m/s)	Precipitation (mm/s)	Downward shortwave radiation (W/m^2)	Downward longwave radiation (W/m^2)
Observed forcing data	287.92	0.0080	101555	2.38		153.41	331.19
Interpolated forcing	287.91	0.0081	101017	2.26		180.53	353.81
RMSE	1.87	0.0019	618.36	1.52	0.0002	126.69	44.27
