Hydrological Evaluation of Satellite Soil Moisture Data in Two Basins of Different Climate and Vegetation Density Conditions

Figure 6

The calibration and validation results using the whole year data. For PB the calibration scatter plots between XAJ SMD1 and SMOS (a) and AMSR-E (c) are presented, and the validation between SMOS derived SMD and original XAJ SMD1 (b) and between AMSR-E derived SMD and original XAJ SMD1 (d) are shown. For FBB the calibration scatter plots between XAJ SMD1 and SMOS (e) and AMSR-E (g) are illustrated, and the validation between SMOS derived SMD and original XAJ SMD1 (f) and between AMSR-E derived SMD and original XAJ SMD1 (h) are shown. It is important to note that, for the calibration, the calculated NSE and RMSE are between the XAJ SMD1 and the satellites’ derived SMD during the calibration period; therefore all the RMSEs shown here are in the unit of meter.
