MODIS Terra and Aqua Products and Data Tools Available from the NASA GES DISC
Abstract
The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), which includes the GES Distributed Active Archive Center (DAAC), distributes three major groups of MODIS products: Level 1 Radiometric and Geolocation data, and Level 2 and higher levels of Atmosphere and Ocean products. The GES DISC provides a broad spectrum of MODIS support for the Earth Observing System (EOS) Project, covering data access, visualization tools, tools for data search and order, documentation, data content, and science and software support. To optimize data access and usage, the MODIS Support Team (MDST) at the GES DISC has developed a variety of tools. The MODIS Multiple Data Ordering Page (MDOP) provides a convenient way to order several MODIS data sets simultaneously, including Level 1, Level 2, and Level 3 products. The MODIS Ocean On-demand Spatial Subsetting tool enables the parameter and spatial subsetting of all MODIS Ocean mapped data products from the GES DAAC Search and Order System. The MODIS L3 Atmospheric products Online Visualization and Analysis System (MOVAS)addresses the "HDF-data-order-free" desire of science users for the on-line study of aerosols, water vapor, and clouds on a large regional to global basis, without downloading huge amounts of data. To increase the distribution capacity of the EOS Core System (ECS), the so-called Data Pool has been added, providing a very large (50 TB) anonymous FTP area for users to directly download data of interest, without having to submit orders to the main tape archive. New information about MODIS data products, tools, and services can be found on the Web gateway for MODIS information at http://daac.gsfc.nasa.gov/MODIS/
