The general difference between ground temperature and air temperature is several degrees

The gap between ground temperature and air temperature varies by location and season.

Under normal circumstances, the difference between ground temperature and air temperature is generally 1.6-2.3℃. Ground temperature is the collective name for the surface and soil temperatures at different depths, and it increases with depth. However, under certain special circumstances, such as in places exposed to direct sunlight in summer, the surface temperature may be 2-3°C higher than the air temperature, while in places exposed to direct sunlight in winter, the surface temperature may be 5-8°C higher than the air temperature.

These conditions all depend on various factors such as solar radiation, atmospheric environment, and geographical location. Therefore, the specific gap between ground temperature and air temperature needs to be measured and calculated based on actual conditions.
