Microwave radiometry is a passive remote sensing technique that measures naturally emitted thermal radiation in the microwave portion (0.3–300 GHz) of the electromagnetic spectrum. In essence, a microwave radiometer detects weak microwave energy from Earth’s surface and atmosphere and expresses it as a brightness temperature, the equivalent blackbody temperature of the emitting source. Unlike optical…

What Is Space Weather and Why It Matters Space Weather refers to the changing environmental conditions in space driven by the Sun’s activity – including bursts of solar radiation, charged particles, and magnetic disturbances. Just as terrestrial weather can produce hurricanes or blizzards, our Sun generates “solar tempests” like solar flares, coronal mass ejections (CMEs),…

Introduction to Weather Satellites Weather satellites are spacecraft orbiting Earth that continually observe atmospheric conditions from above. They serve as “eyes in the sky” for meteorologists, providing a global view of weather systems that ground observers alone could never achieve. By capturing images and data on clouds, storms, temperature, and more, weather satellites supply crucial…
