To investigate the contribution of MODIS inverted vegetation to regional rainfall prediction in numerical model(MM5),two case studies are presented.The MODIS inverted vegetation data used in the studies are from Shaanxi Agricultural Remote Sensing Information Center and denote the summer condition of 2004.Two regional rainfall cases in Northern Shaanxi were chosen arbitrarily in July 2004.The results indicate that the modeling rainfall of the cases can be improved if MODIS inverted vegetation is adopted in MM5 instead of USGS vegetation.
