  1. Access to near real time global visible and thermal band mosaics from NGDC Chris Elvidge and Edward H. Erwin, NOAA-NGDC (chris.elvidge@noaa.gov) Kimberly E. Baugh, Ara T. Howard, Benjamin T. Tuttle University of Colorado Cooperative Institute for Research in the Environmental Sciences (CIRES January 24, 2007

  2. The U.S. Air Force Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) has a Unique capability to collect low-light imagery. Polar orbiting 3000 km swath 2.7 km ground sample distance (GSD) Two spectral bands: visible and thermal Nightly global coverage Flown since 1972 Will continue till ~2012 Visible Thermal

  3. NGDC’s Near Real Time Processing and Delivery System for DMSP-OLS Data

  4. Watch How the Global Mosaics Are Built – One Orbit at a Time! • http://www.ngdc.noaa.gov/eog/nrt/html/mosaic/ut_night/loop/

  5. Open Access to Six km Resolution Visible and Thermal Band Mosaics! • http://www.ngdc.noaa.gov/eog/maps/public/mosaic/ut_night/?SERVICE=wms&VERSION=1.1.1&REQUEST=GetMap&LAYERS=F1620070121.nt.d.OIS.vis.mos.tif&FORMAT=png&&BBOX=110,0,130,20 • Edit the date, band, format (png or geotiff), and bounding rectangle. • Paste into web browser.

  6. Conclusion • Service ready for use and could augment other sources in tracking storms and evaluating their severity. • Three hour hold on distribution of OLS data can be waived through a request to the U.S. government. • A graphical user interface is in development. • Access uses open source web mapping system and web coverage service components which can be shared. • NGDC plans to develop a “most recent” thermal band mosaic that will include day-night and dawn-dusk data. • NGDC plans to establish the same type of service for VIIRS data in 2010.
