Passive microwave sensing of tropospheric water properties near the equator — •Harry Küllmann¹, Bing Tan², Thorsten Warneke¹, Justus Notholt¹, Christian Mätzler³, and Niklaus Kämpfer³ — ¹Institute of Environmental Physics, University of Bremen, Germany — ²Faculty of technology, University of Suriname, Suriname — ³Institute of Applied Physics, University of Bern, Switzerland

In the understanding of climate change observations of tropical water vapor are of primal importance due to its dominant abundance as a greenhouse gas and its high variability. The ground-based microwave sensor TRARA now is operated in Paramaribo, Suriname, since two years. The two channel measurements at 21 and 35 GHz allow for the determination of integrated water vapor and cloud liquid water. Results using new statistical retrieval algorithms based on local radiosonde profiles will be presented.
