Data Sets: Global Water Vapor Project (GVaP)

Blended (Global Precipitation Climatology Project, GPCP) global water vapor and cloud liquid water data sets (NVAP) using radiosonde, microwave, and infrared satellite data with 1 x 1-degree resolution daily, pentad and monthly averages for the period 1988-2001 are available at the NASA Langley DAAC.

The NASA MEaSUREs program began in 2008 and has the goal of creating stable, community-accepted Earth System Data Records (ESDRs) for a variety of geophysical time series. A reanalysis and extension of the NASA Water Vapor Project (NVAP), called NVAP-M, is being performed as part of this program. When processing is complete, NVAP-M will span 1987-2010.
