OCO-2

Target entity: OCO-2
Context triple: [A-Train satellite constellation, includesSatellite, OCO-2]

• A. GPM Core Observatory satellite
  The GPM Core Observatory satellite is a joint NASA–JAXA mission that serves as the centerpiece of the Global Precipitation Measurement program, providing highly accurate, global observations of rain and snow to improve weather forecasting and climate research.
• B. Landsat 8
  Landsat 8 is an Earth observation satellite in the long-running Landsat program, providing high-resolution multispectral imagery for environmental monitoring, land use analysis, and climate research.
• C. Landsat 9
  Landsat 9 is a NASA and USGS Earth observation satellite that continues the decades-long Landsat program by collecting high-resolution multispectral imagery to monitor and study changes on the planet’s surface.
• D. CALIPSO
  CALIPSO is a joint NASA–CNES Earth observation satellite mission that uses lidar and imaging instruments to study clouds and aerosols and their impact on Earth’s climate and radiation budget.
• E. Operational Land Imager
  The Operational Land Imager is a multispectral imaging sensor on Landsat 8 designed to capture high-resolution, calibrated images of Earth’s land surfaces for environmental monitoring and land-use analysis.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
