Short summary
Downward long-wave radiation (DLR) affects energy exchange between the land surface and the atmosphere, while it is seldom observed at conventional radiation stations. Therefore, parameterization of DLR based on the near-surface meteorological variables provides a chance to estimate the DLR over most meteorological stations. This work established three parameterizations suited to estimating the DLR over China by using the measurements from the CBSRN with an accuracy of ~6.1 %.
