| Zusammenfassung |
| Satellites carrying X-band Synthetic Aperture Radars (SAR) have recently
been launched by several countries. These provide new opportunities to
measure precipitation with higher spatial resolution than has heretofore
been possible. Two algorithms to retrieve precipitation from such
measurements over land have been developed, and the retrieved rainfall
distributions were found to be consistent. A maritime rainfall distribution
obtained from dual frequency (X and C-band) data was used to compute the
Differential Polarized Phase Shift. The computed Differential Polarized
Phase Shift compared well with the value measured from space. Finally, we
show a comparison between a recent X-band SAR image of a precipitation
distribution and an observation of the same rainfall from ground-based
operational weather radar. Although no quantitative comparison of retrieved
and conventional rainfall distributions could be made with the available
data at this time, the results presented here point the way to such
comparisons. |
