Fuel Moisture: NASA SPoRT Land Information System

The NASA Short-term Prediction Research and Transition (SPoRT) Center has developed a Real-Time Land Information System (LIS), using satellite-derived datasets, ground-based observations, and model reanalysis to inform weather models with influences from the land surface.

Products are updated on a daily basis and include:

  • Volumetric Soil Moisture represents actual moisture in a soil column.
  • Relative Soil Moisture represents the soil moisture for a given soil column on a relative scale between soil saturation and wilting levels.
  • Column-Integrated Relative Soil Moisture combines 4 column depths down to 200cm.
  • Green Vegetation Fraction-current and trends-from VIIRS.
  • Land surface temperature and Heat Flux.

Soil Moisture products evaluate conditions at five levels:

  • 0-10 cm - relates most directly to the FWI Duff Moisture Code, or DMC
  • 10-40 cm - relates most directly to the FWI Drought Code, or DC
  • 40-100 cm
  • 100-200 cm
  • 0-200 cm Integrated Column

Available at 3km resolutions for the Continental U.S. (CONUS), analysts should consider using the following:

Column-Integrated Relative Soil Moisture products to assess current drought levels and changes over one week, two weeks, one month, three months, six months, and one year.

Green Vegetation Fraction products that are updated daily in lieu of NDVI that are updated on only a weekly basis. Current conditions are augmented by 1-month, 2-month, 3-month, 4-month, and 1-year change products.

Relative Soil Moisture products that may be correlated to fuel moisture contents applied in fire effects and fire spread models. A 0-10 cm 1-day change product provides an assessment of rainfall effects on the top soil layer that relates to fuel moisture in carrier fuels.
