LANCE User Working Group Briefing

1. LANCE User Working Group Briefing Brad Quayle USDA Forest Service Remote Sensing Applications Center (RSAC) LANCE User Working Group Meeting November 16-17, 2010 USDA Forest Service, Remote Sensing Applications Center, FSWeb: http://fsweb.rsac.fs.fed.us WWW: http://www.fs.fed.us/eng/rsac/

2. RSAC X-band antenna in radome Remote Sensing Applications Center (RSAC) • National Technical Center; Located in Salt Lake City, Utah • Mission:Assist all levels of the agency, and external agency partners, in applying the most advanced geospatial technologies for improved monitoring and mapping of natural resources • Operational MODIS direct readout data collection since 2002

3. MODIS Ground Station Network • L0/L2 data continuously acquired and compiled at RSAC for further processing • NASA operational MODIS data distribution systems provide additional coverage and backup ground station network • MODIS Rapid Response System (LANCE) • LAADS UAF SSEC RSAC NASA DRL Area of interest

4. MODIS Data Processing MODIS DR Ground Station Network L2 MOD14 Data via LANCE (every 15 minutes) Selected L0 Data Selected MODIS L0/L2 Data (every 15-20 minutes) International Polar Orbiter Processing Package (IPOPP) used for L0 -> L2 processing L2 Products L0 Data (12-14 GB daily) • IPOPP L2/L3 Products • Active Fires (MOD14) • Land Surface Temperature (MOD11) • Corrected Reflectance (CREFL) • Surface Reflectance (MOD09) • NDVI/EVI (MOD13) • Burn Scar (L. Giglio) • AOD (MOD04) • TPW (MOD05) • Cloud Mask (MOD35) • Cloud IR Phase (MOD06) • Cloud Top Pressure (MOD06) • Sea Surface Temperature (MOD28) L2 Products • (~30 GB daily) L2 Product Stream USFS-RSAC IPOPP Processing System

5. Active Fire Mapping (AFM) Program(http://activefiremaps.fs.fed.us) • Operational, NRT detection and monitoring of wildland fire activity in CONUS, Alaska, Hawaii & Canada • Leverages NASA and NOAA assets • MODIS • AVHRR • Facilitates decision support for strategic wildfire planning and response for U.S. and Canadian fire agencies • Prioritize allocation of fire suppression assets • Focus tactical airborne reconnaissance assets • Integrated into several fire-related applications and decision support systems • GOES • Future polar/geo sensors

6. AFM Value-Added Fire Products • Mapping/Visualization Products • JPG/PDF fire detection maps • Interactive fire detection map viewers • Google Earth fire detection KMLs/KMZs • Detection analysis/summary products • Imagery/Geospatial Data Products • Georeferenced image subsets • Fire detection GIS datasets • WMS/WFS services • Update frequency: Every 15 to 60 minutes or immediately after every satellite observation • Ongoing coordination with fire management community to develop products to meet operational needs

7. MODIS fire detections Example Fire Management ApplicationData Input for Spatial Fire Behavior Systems/Models - WFDSS FS-Pro (Fire Spread Probability) Model • Probability of fire spread from a known location in the absence of suppression • Used for long-term projections of ongoing fires • Used in conjunction with data about values at risk MODIS data provides fire locations for initial model runs when other sources of intelligence are lacking. FS-Pro results help managers determine an “Appropriate Management Response” to fires from a strategic and tactical stand point and prescribe adequate resources for fire containment.

8. Forest Service Direct Readout Data Portal(http://directreadout.fs.fed.us) • NRT L2 MODIS land, atmosphere and ocean products produced by IPOPP • Downloadable L2 swath datasets and value-added products • GeoTiff format • Quicklook maps • Google Earth KMZs • Distribution node for L0 data collected via RSAC antenna • Supports national/regional scale resource management and monitoring

9. Example Monitoring ApplicationForest Disturbance Detection and Monitoring • Annual aerial detection survey (ADS) flights conducted by Forest Service Forest Health Monitoring Program • Specifically map areas of insect, disease or weather-related damage • Prototype MODIS-based change detection program by RSAC identifies forest disturbances/anomalies • Provides information to prioritize ADS flights • Provide guidance on where to go vs. where not to fly (omission and commission error important) • 7-10 day response time

10. Forest Disturbance Detection Products Reflectance composites for change detection analysis Nationwide geospatial disturbance products every 8 days Michigan forest tent caterpillar outbreak 2010 Current year 16-day composite using NRT data Baseline multi-year composite for same 16-day period; “normal conditions”

11. Suggested LANCE Enhancements Data Latency Considerations • Provide information on alternatives for acquiring NRT EOS data to support users with minimal latency requirements • L2 science products < 30-60 minutes post-acquisition are feasible via direct readout (DR) community • Numerous EOS DR ground stations with data distribution portals • Regional DR data sharing networks in place to support NRT application objectives and increase efficiencies • DR data processing technologies are freely available that provide self-contained, scalable frameworks with access to latest SPAs • Increasingly being utilized by DR ground stations • Available to any user to generate higher level products from L0 data

12. Suggested LANCE Enhancements General Considerations • Additional output formats (GeoTiffs, etc.) • File compression for faster download • Additional methods of accessing L2 swath data by FTP download • Index directories by grid referencing system common to the user community (i.e. tiles, etc.) • OGC-compliant data/mapping services • WMS for mapping/visualization • WCS for data extraction and analysis • Integration of custom products for targeted applications • Coordination with other space agencies to facilitate similar NRT data delivery framework for future sensors • GCOM-C SGLI (JAXA) • Sentinel 3 SLSTR (ESA) • GOES ABI (NOAA)
