Contributions of DLR & Partners to the IPY

M. Gottwald, DLR-IMFIPY Space Task Group, Geneva, 17-19 January 2007


Slide 2

Missions and Facilities

DLR – in cooperation with national & international partners – operates various missions and facilities

satellitesground stationsaircraftsensorsdata systems (processors, archives, data dissemination)

usage for IPY is either in framework ofregular operations (e.g. satellite sensors, data systems)dedicated measurements & campaigns (e.g. aircraft sensors)

some satellite missions provide continuous data from polar regions (e.g. SCIAMACHY, GOME/GOME-2)DLR science groups cooperate with partners in IPY related programs (also using non-DLR facilities)

Note: the following list is a summary but does not claim completeness
