Dead fine fuel (e.g., litter) moisture content is an important parameter forboth forest fire and ecological applications as it is related toignitability, fire behavior and soil respiration. Real-time availability ofthis value would thus be a great benefit to fire risk management and prevention. However, thecomprehensive literature review in this paper shows that there is noeasy-to-use method for automated measurements available. This studyinvestigates the applicability of four different sensor types (permittivityand electrical resistance measuring principles) for this measurement.Comparisons were made to manual gravimetric reference measurements carriedout almost daily for one fire season and overall agreement was good (highlysignificant correlations with 0.792?
