Estimated mean monthly and annual (2000-2009) evapotranspiration rates in Nebraska

data/water/regionalet.asp) are a) the ET rates of the winter months (December, January, February) are included in the current annual maps; b) the method became largely automated and thus its application made simpler. The modeling period could have been extended to include 2010, however, the project (GCIP-SRB, http://metosrv2.umd.edu/~srb/gcip/cgibin/historic.cgi) that provided the monthly incoming global radiation values did not get funded recently, thus no radiation data is available after June 2010 from that source. Rather than looking for alternative data sources, the original 10-year long modeling period, i.e., 2000-2009, was kept, thus ensuring that the same data types were employed throughout the study. ping (CREMAP), by the present author.
