Evaporation Atlas for the Contiguous U.S. (1956-1970)
Listed in NASA Earthdata CMR
Maps are presented showing the areal distribution of evaporation in the contiguous 48 states (1) observed from Class A pans from May through October, (2) estimated for a free water surface (FWS) with negligible heat storage from May through October, and (3) estimated for an FWS for the entire year.
Description
A map is presented of coefficients to convert from pan evaporation to FWS evaporation. Sources of data, analyses of the maps, and limitations on their use are described.
The maps are printed on a scale of 1/4,800,000. The data set used included, at most, 15 years. The data sets were adjusted to fit a common base period 1956-1970.

These values are considered a good index to potential evapotranspiration or potential consumptive use. Processing: Estimation equations were used when weather conditions prevented reliable measurements. These data are available in paper copy or microfiche at cost of reproduction.
