Evapotranspiration from Wetland and Open-Water Sites at Upper Klamath Lake, Oregon, 2008–2010


Table 10. Coefficients of fourth-order polynomial fits to biweekly growing season ensemble average Kc values. 


[Polynomials are of the form: Kc = C 0+C 1(X)+C 2(X  2)+C 3(X  3)+C 4(X  4), where 
X = DOY/100. Because of the powers of X involved, all significant digits shown are needed to get accurate results. This number of significant digits did not require use of double precision in FORTRAN. Abbreviation: DOY, day of year]
