Introduction: Satellites Above Us Everyday Satellites have quietly become the unsung heroes of modern life. They play an essential role in our everyday lives, contributing to our well-being and helping meet important needs on Earth asc-csa.gc.ca. From providing the satellite maps we browse on our phones to enabling the GPS navigation in our cars, satellites…

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…

A New Era of Weather & Climate Satellites The period 2025–2033 is witnessing an unprecedented boom in satellite constellations dedicated to weather forecasting and climate monitoring. Around the globe, space agencies and private companies are deploying hundreds of new satellites to observe Earth’s atmosphere, oceans, and environment with greater fidelity and frequency than ever before.…

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…
