Auswertungen ausgewählter globaler Klimamodelle hinsichtlich atmosphärischer Zirkulationsbedingungen im nordatlantisch-mitteleuropäischen Sektor.

Peter Krahe, Enno Nilson, Ulrike Gelhardt & Jürgen Lang
Dieser Datenbestand dient der Analyse atmosphärischer Zirkulationsbedingungen (Wetterlagen, NAO) im nordatlantisch-mitteleuropäischen Sektor wie sie von Reanalyse- und globalen Klimamodellen (Status: 2010) simuliert werden. Ausgewählt wurden solche Klimamodelläufe, die für Mitteleuropa oder Deutschland regionalisiert wurden. Mit dem Datenbestand kann einerseits die Eignung der verschiedenen Modelle zur Reproduktion der beobachteten Zirkulationsverhälnisse (1950-2000) geprüft werden. Andererseits können simulierte Änderungen (2001-2100) ausgewertet werden. Zusätzlich werden Temperatur- und Niederschlagsdaten bereitgestellt, mit denen die Wetterwirksamkeit der Wetterlagen je GCM bewertet werden...

All variables are derived from recalibrated and intercalibrated measurements from SSM/I and SSMIS passive microwave radiometers, except for the SST, which is...

CM SAF Aerosol Optical Depth (AOD) Data Record - Edition 1

Nicolas Clerbaux, Alessandro Ipe, Veerle De Bock, Manon Urbain, Edward Baudrez, Almudena Velazquez-Blazquez, Tom Akkermans, Moreels Johan, Rainer Hollmann, Nathalie Selbach & Martin Werscheck
This CM SAF climate data record provides daily and monthly estimates of the Aerosol Optical Depth (AOD) derived from the Spinning Enhance Visible and InfraRed Imager (SEVIRI) sensors onboard the Meteosat Second Generation (MSG) satellites. Aerosols have many impacts on the climate on our planet: direct through the scattering and absorption of radiation, and also indirectly through the cloud nucleation and precipitation processes. Concerning the direct effect, the most relevant parameters are the AOD and,...

Total column water vapour from the Microwave Radiometer (MWR) instruments onboard ERS-1, ERS-2, and ENVISAT Version 1.1

Ralf Bennartz, Martin Stengel, Marc Schröder, Rainer Hollmann, Bruno Picard & Frank Fell
The Microwave Radiometer (MWR) flown on-board Envisat, ERS-1, and ERS-2 has provided a time series of global microwave observations over a period of nearly 21 years between 1991 and 2012. A successor instrument with very similar characteristics will be carried on-board the Sentinel-3 suite of satellites which will extend the availability of the MWR observations from early 2016 well into the mid-2020s and possibly beyond. Unlike methods relying on infrared or visible/near-infrared techniques, microwave observations...
