Figure 4From: Sensitivity of the reference evapotranspiration to key climatic variables during the growing season in the Ejina oasis northwest ChinaMean daily sensitivity coefficients for air temperature (ST) (a), relative humidity (SRH) (b), wind speed (Su 2 ) (c) and shortwave radiation (SRs) (d) during the growing season in the Ejina oasis. (e) Comparison of mean daily sensitivity coefficients for major climatic variables in the Ejina oasis (SRH is multiplied by -1 to facilitate visual comparison).Back to article page
