Spire Global Validates Hyperspectral Microwave Sounder with First Data

Event summary

  • Spire Global received first data from its Hyperspectral Microwave Sounder (HyMS) demonstrator satellite in March 2026.
  • The HyMS instrument, launched earlier in 2026, captures over 1,000 sensing channels for atmospheric profiling.
  • Data includes temperature, humidity, and precipitation measurements to enhance weather forecasting accuracy.
  • Spire aims to complement its existing Radio Occultation (RO) data with HyMS for comprehensive atmospheric intelligence.

The big picture

Spire Global is advancing its atmospheric intelligence capabilities with the successful validation of its Hyperspectral Microwave Sounder. This development comes as demand for high-quality weather data grows, driven by increasing disruptions in aviation, energy, and agriculture sectors. The ability to provide high-vertical-resolution atmospheric profiling could position Spire as a key player in global weather observation, particularly in data-sparse regions.
