1.5.2 EUMETSAT Satellite Application Facility (SAF) on Climate Monitor 
ing (CM-SAF): 
Within the so-called Satellite Application Facilities (SAF) operated by EUMETSAT, the func 
tions of the lead institution has been assigned to DWD for the tasks of deriving climate rele 
vant parameters from data transmitted by the MSG and EPS/Metop satellites and of estab 
lishing, operating and further developing the 'SAF on Climate Monitoring'. Under the respon 
sibility of EUMETSAT, the SAFs form a European network of specialised centres for the ex 
ploitation of satellite data. The Satellite Application Facility on Climate Monitoring (CM-SAF) 
is one of presently 8 such competence centres. Early 2005, the CM-SAF started the pre- 
operational production of climatologies for radiation, clouds and humidity issues on the basis 
of satellite data. 
In March 2007 the CM-SAF, hosted by DWD, started its Continuous Development and Oper 
ations Phase (CDOP). CM-SAF will continue to provide products (cloud parameters, radia 
tion at surface and top of atmosphere, humidity) in support to climate monitoring and analysis 
on a routine basis. In addition, during the CDOP phase the CM-SAF will provide data sets 
suitable for climate analysis on longer time scales (table for envisaged list of datasets: can 
be found in GCOS SC-XV, Doc. 32: National GCOS Activities in Germany). 
1.5.3 Contributions of the German Aerospace Centre (DLR) 
DLR is Germany's national research centre for aeronautics and space. As Germany's Space 
Agency, DLR is also responsible for the planning and implementation of the German space 
programme as well as international representation of Germany's space interests. 
DLR is involved in various activities related to the provision of ECVs in the atmospheric, oce 
anic and terrestrial domains. Main activities include: 
• Data systems as part of EO mission ground segments 
• The World Data Center for Remote Sensing of the Atmosphere (WDC-RSAT) 
• algorithm development for the retrieval of ECV related parameters from EO data 
• contributions to CEOS Implementation Plan for Climate actions 
• participation in GEO Work Plan tasks, e.g. CL-09-03 (Forest Carbon Tracking) 
1.5.3.1 Data systems at DLR 
As part of the operational ground segments of relevant EO missions operated by ESA and 
EUMETSAT, DLR is responsible for the generation, archiving and dissemination of specific 
products: 
. D-PAF for ERS-1 and ERS-2 
. D-PAC for ENVISAT 
• 03 Monitoring SAF for MetOp-1 
D-PAF and D-PAC are hosted by DLR’s Applied Remote Sensing Cluster, formed by the 
Remote Sensing Technology Institute (IMF) and the Remote Sensing Data Centre (DFD). In 
the consortium for the 03 Monitoring SAF the Applied Remote Sensing Cluster is responsi 
ble for some of the specified ozone products. In addition EO data from other missions, ac 
quired by national and international stations, are analyzed to yield climate related infor 
mation. ECV related parameters retrieved comprise: 
• GOME on ERS-2: total columns of 03 and N02, cloud information 
• SCIAMACHY on ENVISAT: 03 vertical columns and profiles, N02 vertical columns 
and profiles, cloud information 
• GOME-2 on MetOp-1: vertical columns of 03, N02 and S02, tropospheric columns of 
N02, cloud information 
• MERIS: regional Value Added information concerning clouds and aerosol
