Abstract

More accurate weather forecasting requires improvements in vertical temperature profiling.T He increase in vertical temperature resolution along with wind distributions will provide important information on vertical motion fields for Mesoscale weather predictions. Such information is particularly valuable for short-term forecasts and storm tracking. New techniques beyond what can be achieved with the current filter wheel sounders are required. A Michelson interferometer is proposed for the next generation of GOES Sounders. The interferometric spectrometer will greatly increase the spectral resolution of the sounder over the filter wheel instruments, improving its ability to measure temperature and water vapor profiles. This paper describes the current baseline design for the interferometer-equipped GOES Sounder, known as the GOES High-Resolution Interferometric Sounder.
