NVAP Data Sets

The NASA Water Vapor Project (NVAP) total column (integrated) water vapor data sets comprise a combination of radiosonde observations, Television and Infrared Operational Satellite (TIROS) Operational Vertical Sounders (TOVS), and Special Sensor Microwave/Imager (SSM/I) data sets. These data sets span 14 years (1988 - 2001) and contain total and layered global water vapor data. The spatial coverage is global for all data sets.
