3. There is an evaporator and a calibration evaporation rainfall tube.

4. There is a heliometer and a frozen soil pipe.

5. There is a geothermal field, in which there is a maximum geothermal table, a minimum geothermal table, a cm geothermal table, a 5 cm geothermal table, a 1 cm geothermal table, a 15 cm geothermal table and a 2 cm geothermal table, and a geothermal sensor (for automatic station use)

When it comes to electricity consumption, it is the light bulb in the louver, which is required to be less than 25 watts according to the specification.

There is another fence around the observation field, the height of which is less than 1.2m..
