Abstract
An assessment of the spatiotemporal dynamics of air temperature over the territory of the Tyva Republic was carried out for a 64-year period (1961-2024). The data used were ERA5 reanalysis data with a spatial resolution of 0,25×0,25°. The maximum temperature increase rate of 1 °C per 10 years was observed in autumn (September-October). The highest warming intensity of 0,6 °C per 10 years was recorded at elevations of 500-1000 m a. s. l. At elevations of 2200 m and higher, the maximum winter temperature anomaly of 1.28 °C was recorded on northeastern slopes in the Verkhne-Khemchiksky District. Maps of winter and summer temperatures across forest-growing (natural) districts, considering elevation levels, were created using Google Earth Engine.
