NASA’s Plankton, Aerosol Cloud Ocean Ecosystem (PACE) mission UPSC NOTE


  • The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission is a NASA Earth-observing satellite mission launched on February 8, 2024

  • It's a significant program designed to improve our understanding of the interconnected processes between the ocean, atmosphere, and climate.


  • Measure key variables: PACE will collect data on phytoplankton, tiny ocean organisms that play a crucial role in the global carbon cycle

  • It will also measure aerosols (tiny particles) and clouds in the atmosphere, both of which significantly impact Earth's energy balance and climate.

  • Understand complex interactions: By gathering data on these interconnected elements, PACE aims to improve our understanding of how they interact and influence each other. 

  • This knowledge is crucial for predicting future climate changes and mitigating their impacts.

  • Monitor ocean health: Detailed observations of phytoplankton will help monitor ocean health and productivity, contributing to sustainable fisheries management and marine conservation efforts.


  • Advanced instrument: PACE carries the Ocean Color Instrument (OCI), a sophisticated hyperspectral imaging device that can distinguish between different types of phytoplankton and measure their abundance and health.

  • Global coverage: The satellite orbits Earth with a 16-day repeat cycle, providing regular and comprehensive data coverage of the global ocean and atmosphere.
