Abstract
The heat budget of a melt pond surface and the solar radiation allocation at the melt pond are studied using the 2010 Chinese National Arctic Research Expedition data collected in the central Arctic Temperature at a melt pond surface is proportional to the air temperature above it However the linear relationship between the two varies depending on whether the air temperature is higher or lower than 0°C The melt pond surface temperature is strongly influenced by the air temperature when the latter is lower than 0°C Both net longwave radiation and turbulent heat flux can cause energy loss in a melt pond but the loss by the latter is larger than that by the former The turbulent heat flux is more than twice the net longwave radiation when the air temperature is lower than 0°C More than 50 of the radiation energy entering the pond surface is absorbed by pond water Very thin ice sheet on the pond surface black ice appears when the air temperature is lower than 0°C on the other hand only a small percentage 55 of net longwave in the solar radiation is absorbed by such a thin ice sheet
