WHY CALIBRATION? - study period <br />40 <br />•CoAgMet type station data is only available for recent period <br />•Ark Basin: 2-1992, 1-2000, 5-2005, 1-2008, 5-2010, 1-2012 <br />•Water right historical use analysis requires longer study period <br />•ie 1900-, 1950-, 1978- <br />•Many NOAA stations DO have long-term temperature data <br />•Temperature-only ET methods do not provide accurate results <br />without calibration to ET from ASCE Std ET equation using full <br />(temp, RH, solar, wind) climate parameters. <br /> Calibrate NOAA to CoAgMet Station ET for recent period <br /> Apply Calibration to NOAA Station ET for historical period <br />•Simulation of non-temperature data for historical period (for <br />use with ASCE Std) also requires period with full climate data <br />
