| Abstract | A methodology for retrieving vertical temperature profiles in the atmosphere with clouds from radiance measurements made by satellite, using artificial neural networks, is presented. Vertical temperature profiles are important initial conditions for numerical weather prediction models, and are usually obtained from measurements of radiance using infrared channels. Though, when these measurements are performed in a cloudy atmosphere, it is not possible to retrieve the temperature profile with current techniques. It represents a considerable loss of information, since on average 20% of the pixels of the images have clouds. The methodology proposed here consists of a two step inverse problem. The first step is an inverse problem of boundary condition estimation, where the radiance reaching the cloud basis is determined from radiance measured by satellite. The second step consists in determining the vertical temperature profile from the boundary condition estimated in the first step. The results obtained for four test cases show that the methodology produces satisfactory results and has great potential for use, allowing to incorporate information from a wider area of the planet and thus to improve numerical weather prediction models. |
