| Zusammenfassung |
| Spatial and temporal variations of soil moisture strongly affect flooding,
erosion, solute transport and vegetation productivity. Its characterization,
offers an avenue to improve our understanding of complex land
surface-atmosphere interactions. In this paper, soil moisture dynamics at
soil surface (first centimeters) and root-zone (up to 1.5 m depth) are
investigated at three spatial scales: local scale (field measurements),
8×8 km2 (hydrological model) and 25×25 km2 scale (ERS scatterometer)
in a French watershed. This study points out the quality of surface and
root-zone soil moisture data for SIM model and ERS scatterometer for a three
year period. Surface soil moisture is highly variable because is more
influenced by atmospheric conditions (rain, wind and solar radiation), and
presents RMSE up to 0.08 m3 m−3. On the other hand, root-zone
moisture presents lower variability with small RMSE (between 0.02 and
0.06 m3 m−3). These results will contribute to satellite and model
verification of moisture, but also to better application of radar data for
data assimilation in future. |
