A004:
Advances in hyperspectral infrared remote sensing in cloudy atmospheres





Session ID#: 25458

Session Description:
Clouds are a key component in medium range weather forecasting and climate feedback. Clouds are also the most prominent feature in infrared observations from space. However, clouds are not well represented in the medium range forecast and climate models. The models specify clouds as layers of water and ice particles imbedded in the layers defining the temperature and water vapor profiles. Until recently the ability to convert clouds specified by the models into infrared radiances observable from space has been limited by the computational challenge to deal with the Radiative Transfer Model (RTM) under cloudy conditions. This session invites the infrared atmospheric remote sensing community to report on advances in how they deal with clouds, the development of fast and accurate RTMs in cloudy atmospheres, closure between the model clouds and observed clouds, and results from validation campaigns related to clouds and cloudy RTMs.
