Abstract: A laboratory experiment is performed to investigate the sensible and latent heat loss from an open-water surface at very low air temperatures. The time for a fixed volume of water having a fixed surface area to cool down from about 2 to 0.5°C is measured. Since the radiation balance is measured, the sum of sensible and latent heat loss is easily determined. The heat loss rate is found to be proportional to the air temperature deficit. The proportionality factor is 8 Watts/m, °C. This is in agreement with results obtained from a theoretical analysis. Reference is made to field observations.
