EOS-WEBSTER - NEW S<strong>at</strong>ellite Imagery and Model Products inSupport of LBA ScienceAnnette L. Schloss, George Hurtt, Rob Braswell, and Berrien Moore, III.Complex Systems Research Center, Institute for <strong>the</strong> Study of Earth, Oceans, and Space,University of New HampshireDr. Annette Schloss, 446 Morse Hall, 39 College Rd., University of New Hampshire,Durham, NH, 03824, USAannette.schloss@unh.eduAbstractThe University of New Hampshire's WEB-based System for Terrestrial EcosystemResearch (EOS-WEBSTER) distributes a special collection of d<strong>at</strong>a and imagery productsfor <strong>the</strong> LBA community. This collection includes full regional coverage of soils, landcover, NDVI, GOES-8 imagery, and modeled estim<strong>at</strong>es of terrestrial carbon. We alsodistribute IKONOS scenes acquired for <strong>the</strong> LBA tower and field sites. Through <strong>the</strong>leadership of UNH LBA investig<strong>at</strong>ors, EOS-WEBSTER has become <strong>the</strong> central requestand distribution site for <strong>the</strong>se important and very popular s<strong>at</strong>ellite images.Our newest addition is a set of MODIS products th<strong>at</strong> cover <strong>the</strong> entire LBA region. Theseinclude 8-day reflectances (MOD09A1), daily fire products (MOD14A1), and 16-dayNDVI products (MOD13Q1). The regional d<strong>at</strong>a sets were developed in cooper<strong>at</strong>ion <strong>with</strong>Eros D<strong>at</strong>a Center to facilit<strong>at</strong>e use of MODIS products by <strong>the</strong> LBA science community.Regional d<strong>at</strong>a can be clipped to smaller rectangular or irregular areas of interest, such as afield site, a political boundary, or a w<strong>at</strong>ershed. Selected d<strong>at</strong>a are available in severalform<strong>at</strong>s, including GrADS, and can be ordered by ftp or shipped on CD-ROM.This poster introduces <strong>the</strong> EOS-WEBSTER LBA collection, including how to select andorder MODIS d<strong>at</strong>a, and highlights some applic<strong>at</strong>ions using <strong>the</strong> d<strong>at</strong>a. Applic<strong>at</strong>ions includemapping landcover distributions, studying secondary forest regrowth, and quantifying <strong>the</strong>sp<strong>at</strong>ial extent of logging. In <strong>the</strong> future, we plan to provide concurrent d<strong>at</strong>a from severalsensors <strong>at</strong> various resolutions (MODIS, MISR, Lands<strong>at</strong>, IKONOS) for subpixel-levelanalysis. One of our main objectives is to serve <strong>the</strong> LBA community, and we invitesuggestions for making available additional products of general use to <strong>the</strong> LBAcommunity. EOS-WEBSTER (http://eos-webster.sr.unh.edu) is a member of <strong>the</strong> NASA'sFeder<strong>at</strong>ion of Earth Science Inform<strong>at</strong>ion Partners (ESIPs). All d<strong>at</strong>a are registered <strong>with</strong>and searchable through Beija-flor.
