Topofire Soil Moisture Modeling to Support Drought Management and Develop an Updated KBDI for Wildfire Management

NIDIS Supported Research
NIDIS-Supported Research
Main Summary

The objective of this project is to upgrade the Topofire model, a soil water balance model that includes topography, solar radiation, and snow, among other features. The research team will:

  • Generate a near real time, high-resolution (250m grid) soil moisture dataset for the coterminous United States
  • Develop a revised, more physically accurate version of the Keetch-Byram Drought Index (a real-time fire potential index dataset) called "KBDI-ET," that can be incorporated into the Wildland Fire Assessment System managed by the U.S. Forest Service.

These high-resolution gridded datasets will provide critical new tools to support both drought management and wildfire danger assessment.
