Work package EXTRA project

Subproject A: satellite and radar data (DWD)

Duties and responsibilities

• Determination of rain rates, droplet size and geometrical and optical thickness of clouds (Meteosat-8 SEVIRI data)
• Detection of regions with increased instability of Atmosphere (Meteosat-8 Instability-Index)
• Validation of derived products by Meteosat-8 product Multi Sensor Precipitation Estimate (MPE)
• Utilisation of radar products from German Weather Service (DWD) regarding to rain rates (evaluation)
• Validation of single and combined products with the data of Saxon State Agency for Environment and Geology (LfUG) and the DWD meteorological network (Ombrometer)
  

Utilities

• Meteosat-8 (Meteosat Second Generation), 12 channels (temporal resolution: 15 minutes) 
• Radar product RADOLAN (DWD) with a temporal resolution of 1 hour (radar data are adjusted by rain gauge data) and 15 minutes  
• GII Global Instability Index  (EUMETSAT)
  
• MPE Multisensor Precipitation Estimate (EUMETSAT)
  
• Measured data from the DWD meteorological network (Ombrometer)
  
• Conventional precipitation measurements (Pluvios with temporal resolution of 10, 30, 60 minutes; more than 50 stations in Saxony)

Subproject B: Statistical analysis of Ombrometer data (TU Dresden)

Duties and responsibilities

• Development of an operational working  tool for defining the quality of online rain rate data
• Explanation of meteorological network: current for Saxony: 22 Ombrometer supported by LfUG + nearly 30 Ombrometer supported by DWD (launch of measurement stations till the end of 2006); in future: integration of necessary but not yet located Ombrometer
• Analysing of spatial variability of precipitation structures based on orographic effects
  

Utilities

• operational working meteorological network (LfUG Saxony, DWD)
• climate database ("CliSax") (TU Dresden, LfUG Saxony)     
  

Subproject C: Integration of ground based- and satellite data  And Application in a operationel working analysis and decition tool (Tu Dresden, LfUG)

Duties and responsibilities

• Conception and development of a JAVA based analysis and decision tool for diagnosing extreme rainfall events in real time
  
• Integration of data (data based on satellite, radar, Ombrometer, database "CliSax")
• Testing the operational working tool
• Tool installation at operational users in future, like LfUG, DWD, OpAQue
