This tabular data set represents annual average actual evapotranspiration values (millimeters) described in Wolock and McCabe (2017), compiled for the NHDPlus version 2 data suite (NHDPlusV2) for the conterminous United States for the years 2014 and 2015. Linkage of the actual evapotranspiration data with NHDPlusV2 is achieved through the common unique identifier COMID. The actual evapotranspiration values are estimated both for: 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The reach catchment information characterizes data at the local scale, whereas the catchments accumulated through the river network characterize cumulative upstream conditions. The network-accumulated...

This tabular data set represents mean-annual actual evapotranspiration, estimated using the regression equation of Sanford and Selnick (2013) compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for mean-annual actual evapotranspiration was produced by the USGS (Sanford and others, 2013) using the regression equation of Sanford and Selnick (2013). Units are millimeters per year. Reach catchment information characterizes data at the local...
We compared the water balance among the earth's major terrestrial ecosystems. Potential evapotranspiration, actual evapotranspiration (AET) and deficit were derived for each month and year from 19-25-yr climate records at ninety-four sites around the world representing eleven biomes. For each variable, we determined mean annual values. Our focus, however, was to examine temporal variation in AET, which previously has been correlated with large-scale patterns of ecosystem structure and function. Standard deviation of annual AET, an absolute measure of interannual variability, was highest for grasslands and lowest for tundra and taiga. Coefficient of variation of annual AET, a relative measure of variability, was...

The California Basin Characterization Model (CA-BCM 2014) dataset provides historical and projected climate and hydrologic surfaces for the region that encompasses the state of California and all the streams that flow into it (California hydrologic region ). The CA-BCM 2014 applies a monthly regional water-balance model to simulate hydrologic responses to climate at the spatial resolution of a 270-m grid. The model has been calibrated using a total of 159 relatively unimpaired watersheds for the California region. The historical data is based on 800m PRISM data spatially downscaled to 270 m using the gradient-inverse distance squared approach (GIDS), and the projected climate surfaces include five CMIP-3 (GFDL,...

These data are derived from the Basin Characterization Model (BCM) and used as input to a total dissolved solids SPARROW model for the Upper Colorado River Basin. The BCM mechanistically models the pathways of precipitation into evapotranspiration, infiltration into soils, runoff, or percolation below the root zone to recharge groundwater (Flint and others, 2013). The dataset is composed of twelve, 270-meter resolution raster layers representing mean total annual values for water years 1985 - 2012 of actual evapotranspiration (aet), climatic water deficit (cwd), excess water (exc), snowmelt (mlt), snowpack (pck), potential evapotranspiration (pet), precipitation (ppt), recharge (rch), runoff (run), sublimation (sbl),...
