Moisture content sampled at varying depths in the forest floor profile was compared with hourly variations in the Fine Fuel Moisture Code and daily variations in the Duff Moisture Code and Drought Code. Fuel moisture samples were collected in June 2000 and August 2002 from one mature forest stand and four experimental plots that were burned between 1997 and 2000. Forest floor moisture, drying rate, and water-holding capacity varied between the mature, unburned forest and burned plot areas, as well as between surface and subsurface fuel layers within the mature forest. The Duff Moisture Code was the best predictor of forest floor moisture for all the fuel components examined, based on the coefficient of determination (r2 =0.81–0.90) and because its relationship with forest floor moisture more closely resembled relationships observed in previous studies.

NOAA-AVHRR optical and thermal infrared images and SAR images from ERS-1 and RADARSAT were correlated to the Canadian Forest Fire Danger Rating System (CFFDRS) Fire Weather Index (FWI) codes and indices, which were used here as a surrogate of fuel moisture. Results showed that FWI codes and indices were related to optical and thermal infared NOAA-AVHRR data or SAR data, but the relationship was more or less strong with either fast-drying fuel codes or slow-drying fuel codes and indices, depending on the case. The study suggests that the most promising use of satellite images for fire danger rating monitoring is through the combination of optical and thermal infrared images to radar images.
