The InfraRed Sea Surface Emissivity (IRSSE) model

November 23, 2007

From Paul van Delst’s Work Page at The Cooperative Institute for Meteorological Satellite Studies of the University of Wisconsin – Madison Space Science and Engineering Center. The InfraRed Sea Surface Emissivity (IRSSE) model was developed for use in the Global Data Assimilation System (GDAS) at NCEP/EMC. Previously, the GDAS used an IRSSE model based on [...]

Infrared Sea Surface Emissivity

October 9, 2007

“The InfraRed Sea Surface Emissivity (IRSSE) model was developed for use in the Global Data Assimilation System (GDAS) at NCEP/EMC. Previously, the GDAS used an IRSSE model based on Masuda et al (1988). “The Masuda model doesn’t account for the effect of enhanced emission due to reflection from the sea surface (only an issue for [...]
