Relationships between outgoing longwave radiation and diabatic heating in reanalyses
to upper troposphere. The compensating effects in LW and SW radiation are largely linked to variations in cloud fraction and water content (vapor, liquid and ice). These radiative balances in reanalyses are in agreement with idealized calculations using a column radiative transfer model. The overall relationships between OLR and diabatic heating are robust among the different reanalyses, althou...

متن کاملPeriodicity of Downward Longwave Radiation at an Equatorial Location
A good understanding of the diverse mechanisms in the atmosphere is required in modelling the climate. In this study, the diurnal and seasonal patterns of all-sky downward longwave radiation (DLR) at Ilorin (8o 32l N, 4o 34l E), Nigeria were investigated alongside relative humidity (RH) and temperature. The average diurnal pattern of DLR gives an arc that begins by increasing gradually with som...
متن کاملA Study of Longwave Radiation Codes for Climate Studies: Validation with ARM Observations and Tests in General Circulation Models
The equation is deceptively simple, but there are significant problems associated with the calculation of F 0' F c' and N*. Our research program is directed at problems associated with each of the three terms. Nevertheless, we have focused our initial research on the clear-sky problem. Research on homogeneous and broken clouds problems will occupy more of our efforts during the next few years. ...
متن کاملOn the development of a simple downwelling longwave radiation scheme
This paper addresses the refinement and testing of a simple downwelling longwave radiation model. Oklahoma atmospheric surface-layer instrumentation system (OASIS) radiation data in combination with Oklahoma Mesonet weather data were used to evaluate various techniques for estimating downwelling longwave radiation, for daytime and nighttime as well as clear and cloudy skies. The Brutsaert [Wate...
