Short summary
Dead fine fuel (e.g. litter) moisture is a key parameter for wildfire and ecological applications, as it is related to ignitability, fire behavior and soil respiration. For example, fire ignition is highly likely at moisture contents below 10 %, yet nearly impossible above 25 %. Thus, fine fuel moisture measurements are very desirable; however, there is no easy-to-use automated technique available to date. This study investigates the applicability of different sensor types for this measurement.
