| Zusammenfassung |
| This paper presents results of daily rainfall estimates for the flood event
in Albania occurred during the end of September 2002 (from the 21 until the
23). Estimated precipitations based on Meteosat-7 data and computed using
various techniques, are compared with surface based observations. The two
techniques, developed for convective clouds, were employed to screen the
Albanian Flood. On one hand a single Infrared band technique known as
Auto-estimator and on the other hand a three-channel Convective Rainfall
Rate technique known as CRR. Secondly, for both methods, a number of
corrections, such as, moisture, cloud growth rate, cloud top temperature
gradient, parallax and orographic corrections were, also, performed and
tested during the flood case. Preliminary results show that auto-estimator
over-measure significantly daily rainfall with respect to the observed while
CRR gives much closer rain quantities. The Auto-estimator power law curve
was adjusted to the specific conditions using all the available rain rate
gauge measurements. Satellite daily rainfall estimated by the two methods,
corrected and calibrated were finally evaluated using the Albanian rain
gauge network as ground true. |
