1.5.2  EUMETSAT  Satellite  Application  Facility  (SAF)  on  Climate  Monitoring ­
  (CM-SAF):
Within  the  so-called  Satellite  Application  Facilities  (SAF)  operated  by  EUMETSAT,  the  functions ­
  of  the  lead  institution  has  been  assigned  to  DWD  for  the  tasks  of  deriving  climate  relevant ­
  parameters  from  data  transmitted  by  the  MSG  and  EPS/Metop  satellites  and  of  establishing, ­
  operating  and  further  developing  the  'SAF  on  Climate  Monitoring'.  Under  the  responsibility ­
  of  EUMETSAT,  the  SAFs  form  a  European  network  of  specialised  centres  for  the  exploitation ­
  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  preoperational
  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  Operations ­
  Phase  (CDOP).  CM-SAF  will  continue  to  provide  products  (cloud  parameters,  radiation ­
  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,  oceanic ­
  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  responsible ­
  for  some  of  the  specified  ozone  products.  In  addition  EO  data  from  other  missions,  acquired ­
  by  national  and  international  stations,  are  analyzed  to  yield  climate  related  information. ­
  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
