[ABSTRACT] This paper is the continuation of the study of the relationship between satellite phenology of NOAA/AVHRR-derived Normalized Difference Vegetation Index (NDVI) and rainfall in East Asia. That study noted significant differences in NDVI-rainfall relationship for the diverse vegetation types. The current paper examined these differences whether can be explained by relationship between NDVI and air temperature. Therefore, the NDVI and air temperature associations were carried out with several regression analyses: (a) the relationship was analyzed by using a mean annual integrated NDVT and a mean annual air temperature for all 850 stations. It seemed the linear relationship is relatively weak (r=0.40). However, when separated analyses were used with, the monthly time series data of each station, their correlation coefficients were significant for a given stations, which varied from -0.80 to 0.87. (b) Based on mean time series NDVI and air temperature data of each vegetation type in period January 1986 to December 1993, the correlations were linearly significant (r>0.70), except for desert area, r was only 0.49. In addition, when investigating the characteristics of the mean annual air temperature and time lag, we realized the vegetation types did not strongly differ with respect to air temperature analyses.
