Irrigation effects on LST and EVI of maize in Nebraska in 2005 in three selected counties (a to f) and all counties (g, h). Box Butte (FIPS 31013, JJA precipitation: 179.9 mm), Nemaha (FIPS 31127, JJA precipitation: 327.6 mm), and Chase (FIPS 31029, JJA max temperature: 30.7 °C) are relatively dry, wet, and hot counties, respectively, during the study period. Error bars in the three counties (panels a to f) denote the standard error calculated from the original MODIS pixel within each county. Error bars in all counties (panel g and h) denote the confidence interval at 95% by bootstrap (n=1,000) from the county average LST/EVI. The numbers at the bottom of panel g and h are the monthly averaged differences of LST and EVI between irrigated and rainfed maize.
