Background: Soil moisture affects the moisture content of forest fuels and therefore flammability. However, due to the lack of a previously long series of soil moisture data based on observations, previous studies have taken into account fuel and soil moisture by calculating special indices based on meteorological indicators. The growing availability of soil moisture data is now making their inclusion in forest fire risk assessments more feasible. Sources of soil moisture information generally fall into one of three broad categories: in situ measurements, satellite remote sensing, and models. There are no open data on soil moisture measurements, and the soil temperature data series ends in 2013 in Russia.Results: In our work, we present a tool for monitoring soil parameters SMAT-meter. The device is designed for autonomous automatic measurement of soil moisture and temperature, and data transmission to the Recorder Control Center via cellular communication. Power is supplied by a solar panel. SMAT-meter measurements will provide in situ soil moisture and temperature data for forest fire hazard modeling.Conclusions: SMART-meter allows you to organize monitoring of the hydrothermal regime of soils. Weather station data covers the need for atmospheric meteorological data. Copies of the SMAT-meter on various types of soils, organized in a network, in conjunction with weather stations, can provide comprehensive monitoring of the onset of forest fire danger.
