HyMS captures detailed internal views of the Earth’s atmosphere, measuring key atmospheric variables including temperature, humidity, and precipitation.\n \n\n Demand for high-quality atmospheric data continues to grow as weather-related disruptions increasingly impact industries such as aviation, energy, agriculture, government operations, and more. The HyMS demonstrator expands Spire’s weather sensing capabilities, increasing the range of atmospheric observations available to government and commercial customers worldwide, particularly in data-sparse regions and during severe weather events where forecast accuracy is most critical.\n \n\n Microwave sounding data is widely recognized as one of the most impactful inputs for weather forecasting systems, yet traditional microwave sounders typically observe only a limited number of channels. Spire’s HyMS sensor introduces hyperspectral microwave sounding, enabling more than 1,000 sensing channels across key water vapor and temperature bands. This\n \n\n capability supports high-vertical-resolution atmospheric profiling while improving resilience to radio frequency interference (RFI) in critical microwave weather bands.\n \n\n Combined with Spire’s Radio Occultation (RO) data, which captures high-vertical-resolution temperature and moisture profiles, these complementary sensing methods hav...
