These signals, broadcast from instruments orbiting hundreds of kilometers above the Earth, provide the raw observations necessary to track storm systems, monitor sea surface temperatures, and analyze atmospheric composition. Weather satellite frequencies form the invisible backbone of modern meteorology, enabling the continuous stream of data that powers global forecasting models.
High-Speed Digital Streams in Weather Satellite Frequencies
These platforms utilize higher frequency bands for their primary data links, transmitting at S-band frequencies around 2. GOES Satellite Communication Links Geostationary satellites, such as those operated by NOAA under the GOES (Geostationary Operational Environmental Satellite) program, maintain a fixed position relative to the Earth’s surface.
Receivers designed for these frequencies capture critical vertical temperature profiles, humidity soundings, and precise atmospheric motion vectors that are ingested by supercomputers to generate accurate forecast models. This band is designated for Meteorological Aids to Navigation and Weather Satellite (M-AWS) services.

NOAA APT and Meteor M2 Frequencies Among the most well-known signals is the Automatic Picture Transmission (APT) from the NOAA polar-orbiting satellites, which broadcasts visual and infrared imagery at a frequency of 137. Additionally, the L-band spectrum around 1.
