Abstract

Abstract A new formula is proposed for estimating the long‐wave radiation from clear skies. The formula depends on screen‐level air temperature and water vapour pressure. The formula has been extensively tested using long‐wave measurements covering a large range of environmental temperatures (–40 to +40°C), and by using radiosonde profiles and an accurate radiative‐transfer model (Lowtran–7). It is shown that the new formula out‐performs five other widely used formulas.
