Advancing Earth Observations from Small Satellites

The field of Earth observation has been revolutionized over the past decades by the advent of satellite technology. Long-term observations from these satellites have become crucial in advancing our understanding of the global Earth system's complexity. However, there are ongoing debates and questions regarding the cost, flexibility, and development time of larger satellite missions. Recently, the development and deployment of small satellites, including CubeSats, have been increasingly advocated for remote sensing of Earth's various components. These smaller satellites offer more flexibility, shorter development time, and lower manufacturing and launch costs, but there is a need for further investigation into their potential and limitations.

The primary aim of this research topic is to consolidate expertise in the development and application of small satellites, particularly focusing on Earth observations. The goal is to explore the potential of these smaller satellites in conducting rapid-response, high-priority, and high-quality science. This includes investigating their scientific impacts, addressing the challenges and issues related to their operation, and advancing small-satellite data processing and science products.

To further our understanding of small satellites' potential and limitations, we welcome articles addressing the following themes:
• Design and implementation of small satellites and payload sensors for observing Earth system components, such as the atmosphere, ocean, land surface, and ecosystem, among others;
• Use of small satellite measurements for studying any above-mentioned component of the Earth system or the interactions between those components;
• Investigations of the scientific impacts of planned or future Earth-observing small satellites;
• Challenges and issues for operating small satellites and small-satellite constellations;
• Development and advancement on small-satellite data processing and science products.
