  1. WRF-Smoke Dispersion Model System Description and Initial Implementation Plan

  2. Outline • Purpose • System Overview • Prediction Method • Development Summary • Computational Environment

  3. Purpose • Develop an operational system • Predict PM2.5, Ozone, CO & other pollutants downwind from fires. • Use state of the art models to predict: • Fire growth & emissions • Pollutant transport • Chemical reactions during transport • Initialize system with current satellite data

  4. Administration Activities Control Postmortem Activities Data Archive Data Search Data Extraction System Overview • Thetus will manage all components. • RED components will have to be made manageable by Thetus. Automatic Activities Prediction Notification Product Generation Website Update

  5. MODIS Overpass Process to fire area Process to AOT Ingest to FARSITE Archive AOT & Fire area Repeat for all designated fires Run FARSITE Extract prediction of emissions Ingest to WRF-chem Setup and run WRF-chem Generate web products Archive smoke transport prediction Prediction & Product Generation • Bring under Thetus management: • RR MOD14 algorithm • Burn scar algorithm • Production of fire area from hotspots or burn scar • FARSITE data/runs • WRF-chem data/runs • Product generation

  6. Major Development Areas • Generation of burned areas from MODIS data. • Acquire computer for WRF runs • Initial setup of WRF CONUS domain • Non-GUI FARSITE • Reformat data between components • Integration of components into Thetus

  7. External ISP Connection NWS Network SEM Web Services MODIS DB Station Hotspot database 2 Linux MODIS DB processors Current hotspot map Linux fileserver/FCHuey Current smoke prediction Linux/Thetus server National Weather Service WRF-chem Computer Where to put this? ?/FARSITE server System Environment

  8. Thetus questions • For archive browsing: can the webserver be separate from the Thetus server? • What is the mechanism for triggering a processing chain on remote machines? Need a client or is ssh sufficient?

  9. National Burned Area DB Network Firelab DB Firelab FARSITE server RSAC DB Firelab Thetus server GSFC DB Firelab WRF server Florida? DB ….
