James G. Acker, SSAI Goddard Earth Sciences Data and Information Services Center/ Distributed Active Archive Center The Goddard Earth Sciences Data and Information Services Center / Distributed Active Archive Center (GES DISC/DAAC) is recognized worldwide as the preeminent source of remotely-sensed ocean color data for oceanographic research. The GES DISC/DAAC provides system expertise, dedicated user support, and information and educational resources to supplement its data archive and distribution mission COASTAL ZONE COLOR SCANNER (CZCS)  Online WWW access to full archive of nearly 60,000 2-minute Level 1A scenes  “CZCS Classic Scenes” educational resource, utilized as a reference in both high school and undergraduate environmental science and oceanography classes  “Observing the Ocean from Space” educational resource  Full dataset documentation Sea-Viewing Wide Field-of-view Sensor (SeaWiFS)  Full mission archive, September 1997-present, including Level 1A LAC, HRPT LAC, Level 1A and Level 2 GAC, and Level 3 binned and SMI products  Spatial and temporal search engine; rolling archive of HRPT subsets for high-interest areas; data product subscriptions with geographic area specification; parameter subsetting  Search engine includes cloud cover and ocean area search capability for HRPT station data  Concurrent acquisition of ancillary data used in SeaDAS processing for any data request size (one file to 10,000 files)  Data available by FTP, tape media, and CD-ROM  User query tracking in User Assistance System; data order tracking in archive and distribution system  Science Focus! series educational resource: articles on various topics pertaining to remote-sensing of the oceans and Earth surface  SeaWiFS Poster Teaching Supplement: document and WWW page with links to information related to images on the SeaWiFS Project poster  Complete dataset documentation OCEAN COLOR AND TEMPERATURE SCANNER (OCTS)  Provides ocean color data for November 1996-June 1997, just prior to the SeaWiFS mission  The GES DISC/DAAC archives the SIMBIOS-NASDA- OCTS reprocessed data set.  Level 1A GAC, Level 2 GAC, and Level 3 data files correspond to the SeaWiFS geophysical products suite.  The data files are compatible with the SeaWiFS Data Analysis System (SeaDAS) atmospheric correction algorithms, using ancillary meteorological  Data set organization is similar to the organization of the SeaWiFS data set. All search methods and data access system functions at the GES DAAC operate in the same manner as for the SeaWiFS data access system. Moderate Resolution Imaging Spectroradiometer (MODIS) TerraAqua  Mission archives: MODIS-Terra covers February 2000 – February 2004; MODIS-Aqua covers July 2002 – February 2004; MODIS Terra and Aqua sea surface temperature data available for full mission (to present)  Original MODIS Ocean data products, including multiple chlorophyll algorithms, chlorophyll fluorescence, coccolithophore calcite concentration, absorption coefficients, PAR, and data quality information  Level 1A, Level 2, Level 3 and Level 4 (model) data products  Several different data access gateways, including the Multiple Data Order Page and the 50 Terabyte online Data Pool for popular, extensively utilized data products  Comprehensive dataset documentation; complete description of all MODIS Ocean data products  HDFLook data processing software modified for MODIS data processing capability; allows visualization, multiple granule merging, mapping into various map projections  Additional tools created for IDL and Geographical Information Systems (GIS)  Convenient on-the-fly subsetting capability for single or multiple files Customized on-demand spatial and parameter subsetting  Data distribution by FTP, tape media, or CD-ROM OCEAN COLOR PANORAMA OCEAN COLOR TIME-SERIES PROJECT WEB SITE Laboratory for Ocean Color Users (LOCUS) Ocean Color Panorama is a GES DISC/DAAC“Geoscience Collaboration” established in It was designed to serve as a starting point for WWW access to data, information, and resources pertinent to the international ocean color scientific community. In addition to the DISC/DAAC ocean color archive, Ocean Color Panorama features mission information for other satellite sensors, frequently updated “News and Announcements” pertaining to ocean color science and applications, and links to other ocean color and related environmental data sources. The Ocean Color Time-Series Project Web Site will provide an online home for the REASoN-CAN ocean color time-series project (Dr. Watson Gregg, Principal Investigator). The primary goal of this project is the development and maintenance of a consistent multi-decadal time series of ocean color data. The GES DISC/DAAC will host the reprocessed datasets created by this project. Data access will be augmented by online analysis tools which will allow the generation of regional time-series and publication-ready statistical analyses without the need to download any data files. Status reports, documentation, meeting announcements and proceedings, and other information related to this project will be found here. The second goal of the Ocean Color Time-Series Project is to provide simplified user access to the datasets created by the project. The Laboratory for Ocean Color Users (LOCUS) will expand on this goal by providing an environment for the demonstration and development of research using the datasets and analysis tools available at the GES DISC/DAAC. Tutorial projects, collaborative research projects shown in progress, and interaction with experienced ocean color scientists as advisors and co-investigators will provide a unique system, allowing researchers with varying levels of skill and experience to productively utilize ocean color data for their own specific interests.
