The RSS Monthly 1-deg Microwave Total Precipitable Water netCDF V7R00 dataset provides 1 degree gridded data for the monthly means of total precipitable water, a 20 year climatology file, and a cumulative file with data from 1988 to the current month. This includes the anomalies for global mean precipitable water over Ice Free Oceans (60S to 60N) and the tropical mean for 20S to 20N. Satellite information used in calculating the means is included for the SSMI (8, 10, 11, 13, 14, 15) and SSMIS (16, 17), AQUA10 and Windsat(Coriolis). This dataset contains both netCDF3 and netCDF4 formatted files.
