The Nevzorov probe is an instrument that measures the total water content of the sample of air which passes through it. It flew on the NASA DC-8 during the CAMEX-4 experiment. The Nevzorov probe is a so-called hot-wire device. Two resistors are heated to evaporate all hydrometeors that touch their surfaces during the flight. Due to their shape they are able to catch small droplets or droplets and ice crystals. The amount of energy necessary to evaporate particles is a direct measure of the liquid water content of the hydrometeor (liquid or frozen) and also gives an indication of the water vapor present.
