For example, the calculations of Haywood et al. (1999) showed that the clear - sky outgoing flux at the TOA over oceans yields excellent agreement with Earth Radiation Budget Experiment (ERBE) observations when aerosol species are considered.
The zonal outgoing longwave (LW) fluxes corresponding to ERBE clear sky are in general about 2 - 10 W / m2 higher than those from the ScaRaB - adapted ISCCP clear - sky identifications.
