ABOUT PRODUCTION DISTRIBUTION USER SERVICES QA DOCUMENTS RELATED SITES FAQ

Welcome to the MODIS Adaptive Processing System (MODAPS) Services website. The website is intended to provide user information concerning all aspects of MODAPS data production, archive, and distribution. The website is a companion to LAADS Web, which provides access to the data products archived by MODAPS in the Level 1 and Atmospheres Archive and Distribution System (LAADS).

This website covers a very wide range of topics in considerable detail. The website has been designed to accommodate a range of users from "first-time" users who, perhaps, have very limited knowledge of MODIS and MODAPS services to experienced users who are searching for a specific detailed piece of information. To that end, the site includes summary material for the former (About) and a "Quick Links" feature that allows an experienced user to navigate to a detailed level in a rapid manner. Please send any comments or suggestions concerning the success, or otherwise, of this strategy to Gang Ye at Gang.Ye-1@nasa.gov.
