GEWEX NASA Water Vapor Project (NVAP) 

A five year (1988-1992) total and layered global water vapor
data set on 1 degree by 1 degree grids.  This set is derived from
radiosonde observations, TOVS and SSMI data. Precipitable
water content (PWC), layered PWC and cloud liquid water
path (LWP) are the main products with supplemental products
of each data source.  The cloud LWP is over global oceans
only.  Daily, monthly, yearly and 5-day averaged grids
are available.
