Abstract

Data from the Moderate Resolution Imaging Spectroradiometer (MODIS) have been used widely to map global scale net primary production (NPP) since its first launch in 1999. Over the years, on-ground flux tower measurements using the eddy covariance method have been used to validate the global MODIS NPP at a number of test sites. However, until now MODIS satellite data have not been adequately tested to map local NPP despite the use of field flux tower measurements for validation. This is due to the low spatial resolution (1 km x 1 km) of MODIS satellite data and the variability of NPP with locations. Therefore, in this present study micrometeorological approach referred to the Monteith’s equation is then used to map local scale NPP in tropical rain forest. Three types of MODIS satellite data band which are visible band, near infra-red band, ocean bands (band 11 and band 12) have been utilized to the micrometeorological model. The result shows that the estimated values for distribution of NPP for the whole Peninsular Malaysia and local scale Pasoh Forest Reserve were 804.37 gCm2y-1 and 633.85 gC m2 y-1, respectively in year 2004.
