Abstract

Recently reported measurements by the Meteorological Research flight C-130 aircraft over the tropical Atlantic have shown that existing models of infrared water vapour continuum absorption underestimate its magnitude by up to 30%. This paper presents additional results from more recent measurements made close to the south-west approaches of the British Isles and over the eastern Mediterranean Sea. These measurements are compared with two models: GENLN2, a line-by-line model, and the widely used band model LOWTRAN7. The measured radiances suggest a consistent underestimate in both models of the water vapour continuum absorption. As with the tropical results, increasing the self-broadening coefficient by a constant factor, or increasing the temperature dependence, improves the agreement between the measurements and the model predictions. -from Authors
