The paper presents a description of the atmospheric-soil measuring complex (ASMC) intended for mobile and stationary long-term automatic measurements of the basic parameters of the atmosphere, soil and water. The device developed by the Institute of Monitoring of Climate and Ecological Systems of the SB RAS has a number of differences from analogues. To substantiate the possibility of using the device as a meteorological value meter, the data of measurements of air temperature and humidity, soil temperature, snow cover depth were verified. The data obtained by ASMC were compared with standard meteorological instruments. As a result of the analysis, high correlation coefficients between the time series were obtained. The average error of air temperature in the ASMS measurement is less than 0.2°C, and 91% of the measurements are within ±1° C. The average air humidity error is 5%, 70% of the measurements are within 5% of the error, and 95.5% of the measurements are within 10% of the error. The average error in soil temperature measurements during the warm period is 0.5°C, during the cold period is 1.5°C. The average error in measuring the snow cover depth is 5 cm and 90% of the measurements do not exceed it.
