WMO RA VI in the aim of guaranteeing highest standards of atmospheric radiation meas 
urements in WMO RA VI Europe. 
The MOL-RAO actively contributes to several sub-projects of the Global Energy and Water 
Cycle Project (GEWEX) being part of the World Climate Research Programme of WMO. This 
includes participation in the Coordinated Enhanced Observation Period (CEOP), GEWEX 
Atmospheric Boundary Layer Studies (GABLS) and GVaP projects. 
2.3.3 AWI - cooperation with other organizations 
The data from Neumayer station helps to close significant gaps in the global weather and 
climate observing networks. The station is part of the GCOS-, GAW-, the Network for the 
Detection of Atmospheric Composition Change (NDACC, the formerly Network for Detection 
of Stratospheric Change, NDSC) and the Baseline Surface Radiation Network (BSRN). Its 
data are also exchanged via WMO’s Global Telecommunication System (GTS). 
Another important station with global monitoring is the AWIPEV station (former Koldewey 
station) in Ny Alesund on Spitsbergen. 
2.3.4 UBA - cooperation with other organizations 
The data from the GAW station ‘Zugspitze’ is also integrated in the UBA air quality network 
which contributes to EMEP. In addition, the GAW platform provides data for research activi 
ties of other scientific projects in the Environmental Research Station Schneefernerhaus. 
The GAW regional station Schauinsland also contributes to the EMEP. In addition, the sta 
tion serves as platform for research projects (e.g. CarboEurope-IP funded by EU) and is re 
sponsible for quality assurance of the greenhouse gases measurements within the total 
UBA-air monitoring network. 
Neuglobsow also serves as well as an EMEP site. In addition, the station is one of two Ger 
man Integrated Monitoring sites within the international cooperative programme of the 
CLRTAP which investigates the effects of air pollutants on ecosystems. 
All in all there exist 21 regional GAW stations in Germany, one for example is Zingst. This 
station is included into Table 1c) in the next section. 
2.4 National meteorological observations 
The following tables (1a- 1c) give some detailed information on the contributions of the na 
tional observations. 
General information for the historical data: 
The National Climate Data Centre (Nationales Klimadatenzentrum, NKDZ) at DWD provides 
historical and current climate data observed in Germany. The database contains the data 
generated by the surface and upper air observational networks of DWD. The time resolution 
of the observations comprises minutes, hours, days and months: the number of observation 
stations differs according to observation time, time resolution and element. The length of time 
series may at some stations extend 100 years and more. The NKDZ provides products gen 
erated from the observational data like climate indices for months, seasons and years and 
produces grid fields with a 1-km-resolution as basis for more advanced products like time 
series of area means. 
Not all records of climate data generated before 1969 are yet digitized and imported into the 
database of the NKDZ. So DWD is currently running a project for data rescue (KLIDADIGI)
