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. In fact, forecasts indicate over 5,400 Earth observation satellites will be launched from 2024 to 2033, nearly triple the number from the previous decade Mundogeo. This surge is driven by advances in miniaturization, lower launch costs, and the urgent need for high-quality data on weather patterns and climate change. The result is a rapidly expanding network of satellites – from large next-generation meteorological observatories to swarms of CubeSats – that promise global coverage, faster revisit times, and new environmental insights. This report provides an overview of this landscape, examining major government programs, private-sector constellations, upcoming missions, technological trends, and the market and geopolitical forces shaping this boom.
