Abstract
The main indicators of potential fire hazards are temperature, relative humidity, precipitation, and wind speed readings. Prompt detection of fire risk should be an integral part of forest protection systems. For this purpose, it is essential to use automatic instruments based on comprehensive meteorological observations. In recent years, most forest fires in the Republic of Buryatia have started due to natural rather than anthropogenic causes. To assess the risk of forest fire based on current weather conditions, the Nesterov index is used. Continuous GPS measurements, combined with highprecision geodetic techniques, allow us to regularly obtain data on tropospheric signal delays, which provide information about the total water vapor content in the atmosphere (IWV). The possibility of using the IWV values obtained to assess the fire risk of forest areas is demonstrated, taking into account data from the Ust-Barguzin weather station located on the territory of the Trans-Baikal National Park. Creating an online resource based on Nesterov's complex indicator using GPS measurements and meteorological data would allow for real-time monitoring of fire risk in forests.
