The wide spatial variation of freeze temperature distribution in Florida is very difficult to assess using conventional ground-based measurements. Thus, the NOAA satellite AVHRR images were implemented in this study to create the temperature distribution over peninsular Florida for 18 and 19 Jan. 1997 freezes. The thermal band of the AVHRR images were also compared with 82 weather stations measurements. Deviations between ground-based point temperature and satellite- derived temperature for these two freeze days were within 3ordm;C in 85%, within 2ordm;C in 63%, and within 1ordm;C in 35% of the samples taken. This result implies that using NOAA satellite AVHRR images is a feasible means to assess the freeze temperature distribution in Florida.
