Description :
Some ecological applications and energy budget calculations of the earth's surface require accurate estimates of incoming longwave radiation. As cloud cover observations are not conducted frequently in high-mountain environments, a new model for the parameterization of daily mean incoming longwave radiation is proposed based on global radiation instead of cloud cover. Besides global radiation, the new model requires data for air temperature, relative humidity, and an estimate of daily mean cloudless global radiation. The model was calibrated with data from high-mountain and lowland stations and the results are compared with existing models.
