Monsoon Asia Integrated Regional Study (MAIRS) is an international program that attempts to understand the interactions between environment changes due to natural variation and human activities and the Asia monsoon climate, in particular that associated with the land cover changes. The study, especially with the GIS and application, requires higher resolution products as the land cover changes happen in the local to regional scale. The MODIS land products of 250m to 1km resolution make such study possible. However, the higher resolution MODIS data files are distributed in tiles due to large data volumes. To conduct the time series study, it requires one to download all tiles that pass the study area for the entire study time period and mosaic tiles. This is a time consuming work. In supporting MAIRS program, NASA GES DISC (Goddard Earth Sciences Data and Information Services Center) has processed MODIS land products for the Asia monsoon region and integrated the data into the Giovanni system (Goddard Interactive Online Visualization ANd aNalysis Infrastructure) that enables users to explore, analyze, and download data easily. Available MODIS land products includes vegetation index, land surface temperature, land cover type, active fire, etc. This presentation will demonstrate the seasonal and interannal changes of vegetation index due to land cover changes by using Giovanni.
