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.
