Zusammenfassung |
Within the European Union FP6 FLASH project, we have generated a cloud-radiation database
(the FLASH database) using numerical simulations of 23 FLASH heavy-precipitation events
over the Mediterranean region, that have been performed by means of the University of
Wisconsin – Nonhydrostatic Modeling System (UW-NMS) in conjunction with an
appropriate radiative transfer scheme that simulates the upwelling brightness temperatures
(TB’s) that would be measured by satellite-borne microwave radiometers. At the same time,
we have developed a new approach for precipitation retrieval from space – which we call the
Cloud Dynamics and Radiation Database (CDRD) approach – that incorporates lightning and
environmental/dynamical information in addition to the upwelling TB’s so as to reduce the
retrieval uncertainty and improve the retrieval performance. In this paper, we describe the
FLASH database for heavy precipitation events, the CDRD algorithm, and our retrieval
results for a series of case studies that have been considered within FLASH. In addition,
we show the comparison of these retrievals with available ground validation data. |
