Under a National Aeronautics and Space Administration (NASA) peer-reviewed contract, STC-METSAT has produced a multi-year total and layered (1988-1999) global water vapor data set. The total column (integrated) water vapor data set is comprised of a combination of radiosonde observations, Television and Infrared Operational Satellite (TIROS) Operational Vertical Sounder (TOVS), and Special Sensor Microwave/Imager (SSM/I) data sets. The global layered water vapor data set is created by slicing the total water vapor data set using layered information that TOVS and radiosonde data provides. As a companion data set for analysis, STC-METSAT also prepared a global (over oceans only), integrated cloud liquid water data set (since the best global climate models now contain liquid water as an explicit variable). The complete data set (all three sets) has been named NVAP, an acronym for NASA Water Vapor Project. STC-METSAT developed methods to process the data at a daily time scale and 1 degree x 1 degree spatial resolution. This work has become an internationally accepted contribution to the World Climate Research Programme (WCRP).
NVAP-Next Generation (NVAP-NG) is the latest phase of the NVAP data set, extending it into years 2000 and 2001. With increased power in computers and satellite sensors, the NVAP-NG data products bring increased spatial and temporal resolution. for all specific information relating to the NVAP-NG data sets, please view the Science and Technology Technical Report 3333 (PDF).
