28 International Cooperation

29 CMA & CEOS CMA s DunHuang Cal/Val site is one of the CEOS LandNet Reference Sites CMA recently participated the experiments in Tuz Gölü Lake organized by WGCV/IVOS

30 CMA recognizes Summary the human being is facing more and more severe challenging such as environment deterioration, and climate change, and deeper understandings of the Earth system are urgently needed for correct decisions; the spaceborne observations by satellites are one of our most important measures to comprehend the earth; dedicated in developing continuous operational meteorological satellite series and improving the application capabilities.

31 CMA appreciates CEOS more and more important role in coordinating global earth observations, and its plenteous achievements in satellite data acquisition and distribution, calibration and validation, as well as outreach and education. NSMC is willing to take part in CEOS activities as a member, to fulfill the obligations by the CEOS terms of reference, and together with other CEOS members to promote the earth observation from space for the benefit of the whole world.
