mages provide per-pixel temperature and emissivity values at 1-km spatial resolution for the 8-day composite product. Temperatures are extracted in degrees Kelvin with a view-angle dependent algorithm applied to direct observations. This study utilized average daytime land surface temperature measurements for 8-day composite periods throughout the growing season (Figure 2). More than twenty five 8-day periods beginning in early April through the end of October were processed. Table 2 shows the MODIS day of year representing the first day of the 8-day MODIS LST composite period and corresponding calendar
