An international team of researchers (USA – University of Wisconsin, NCAR Boulder, UK, Japan, China)Â surveyed the best practices for the observation and use of satellite infrared sounder and imager measurements demonstrating significant improvement in the forecasting of high-impact weather events such as hurricanes and typhoons. They reviewed development of satellite infrared data assimilation by various practitioners and the solutions they have deployed to better use such data in forecasts. They found that use of these cloud-cleared radiances in data assimilation improves the forecasting of high-impact weather events such as tropical cyclones and is now being applied in numerical models to improve daily forecasts. Placing a high-spatial-resolution imager and a hyperspectral infrared sounder on the same platform was crucial for enhancing the effectiveness of infrared data assimilation under cloudy skies. They outlined and discussed the major challenges and future directions…read more. Open Access TECHNICAL ARTICLEÂ
