The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission is a constellation of four smallsats focused on observing the tropical regions of the globe. Each smallsat hosts a millimeter-wave sounder that provides vertical profiles of temperature and humidity, along with imagery at 91 and 205 GHz to detect precipitation-sized ice. Following the launch of a pathfinder satellite to sun-synchronous orbit in June 2021, four additional smallsats were launched into a 30-degree inclined orbit in May 2023. This orbital configuration produces a median revisit rate of about 60 minutes in the tropics, enabling the observation of fast-changing processes in tropical convective systems not well observed by polar-orbiting sensors. This session will provide an overview of TROPICS products, including microwave brightness temperatures, thermodynamic profiles, rain rate, and tropical cyclone intensity estimates. Applications of these products in process studies, data assimilation, and operational forecasting also will be presented.
