Technical report of a rainfall temperature control system for rainfall simulators

The rain temperature is continually monitored by thermocouples, located very close to the disk. IR remote sensing results showed that the real temperature of the drops hitting on the ground surface differed from that measured with thermocouples by maximum 1° for the coldest simulated rain (2 °C), and −3° for the hottest one (35 °C), hence the continually monitoring temperature error is negligible.
