Javadhu Hills is one of the natural bioreserves of Eastern Ghats, Tamil Nadu, India. This hill lies between 78°35” and 79°35” East longitude and 12°24” and 12°55” North Latitude with an area of 2405 square km. MODIS Satellite data is used to map local scale NPP for Javadhu Hills in Tamil Nadu, India. NPP maps for four different seasons namely (Southwest Monsoon, North East Monsoon, winter and summer season were generated for the years 20082009 using MODIS 09A1 surface reflectance products. “Micrometeorological approach” of Monteith's equation and “Production efficiency approach” by Goward and Ruimy were also attempted. Best of both the approaches were used in this study for NPP estimation of Javadhu hills. This study explains the temporal variation of NPP between different seasons. NPP and NDVI values are higher for the North east and South west monsoons comparatively lower for winter and lowest for the summer season. Thus this study gives an insight to identify the significance of Micrometeorological parameters affecting seasonal NPP values.
