  • A. Thermal Infrared Sensor
    The Thermal Infrared Sensor (TIRS) is a Landsat 8 instrument that measures Earth’s thermal radiation to monitor surface temperature and support applications such as water management and climate studies.
  • B. Advanced Spaceborne Thermal Emission and Reflection Radiometer
    The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a high-resolution imaging sensor on NASA’s Terra satellite used to map and monitor Earth’s surface temperature, elevation, and reflectance for scientific and environmental applications.
  • C. Earth Radiation Budget Satellite
    The Earth Radiation Budget Satellite was a NASA spacecraft designed to measure how much solar energy the Earth absorbs and radiates back into space, improving understanding of the planet’s climate system.
  • D. AVHRR
    AVHRR is a spaceborne radiometer used on polar-orbiting weather satellites to measure Earth’s surface and atmospheric properties across multiple spectral bands for meteorological and environmental monitoring.
  • E. GISTEMP global surface temperature record
    The GISTEMP global surface temperature record is NASA’s long-running dataset that tracks and analyzes changes in Earth’s average surface temperature over time to monitor global warming and climate trends.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
