COSMIC update: Scientists enthusiastic about preliminary results

Since the successful launch of COSMIC last April, initial results show that the set of six satellites is probing the atmosphere in ways that were impossible with previous observing systems. COSMIC’s global coverage is providing new information on the atmosphere’s temperature and water vapor structure and allowing researchers to collect measurements above some of the more inaccessible parts of the globe, such as Antarctica and the remote Pacific Ocean. Scientists expect the data to boost the accuracy of hurricane forecasts, improve long-range weather forecasts, and help them monitor climate change with greater accuracy.

These images show how COSMIC data helped a computer model simulate the early development of Hurricane Ernesto in the eastern Caribbean. Each image shows a 66-hour forecast of cloud-water concentration that resembles a satellite photo. The forecasts are valid for 8:00 p.m. Atlantic Standard Time on August 25, 2006. For the image on the left, the model’s starting-point conditions included 15 profiles from COSMIC of atmospheric conditions in and near the Caribbean. When the COSMIC profiles were not included (image at right), the model was unable to show Ernesto’s formation. (Images courtesy Yongsheng Chen, ESSL/MMM.)
