| Zusammenfassung |
In order to evaluate the reliability of the soil moisture product obtained
by means of the LISFLOOD hydrological model (De Roo et al., 2000), we
compare it to soil moisture estimates derived from ERS scatterometer data
(Wagner et al., 1999b).
Once evaluated the effect of scale mismatch, we calculate the root mean
square error and the correlation between the two soil moisture time series
on a pixel basis and we assess the fraction of variance that can be
explained by a set of input parameter fields that vary from elevation and
soil depth to rainfall statistics and missing or snow covered ERS images.
The two datasets show good agreement over large regions, with 90% of the
area having a positive correlation coefficient and 66% having a root mean
square error minor than 0.5 pF units. Major inconsistencies are located in
mountainous regions such as the Alps or Scandinavia where both the
methodologies suffer from insufficiently resolved land surface processes at
the given spatial resolution, as well as from limited availability of
satellite data on the one hand and the uncertainties in meteorological data
retrieval on the other hand. |
