While scientists around the world are confined to their homes during the COVID-19 pandemic, Earth observing satellites continue to orbit and send back images that reveal connections between the pandemic and the environment.

Earth-observing instruments on satellites and aircraft are mapping the current fires, providing data products to agencies on the ground that are responding to the emergency.

Terra Instruments

Terra collects data about the Earth’s bio-geochemical and energy systems using five sensors that observe the atmosphere, land surface, oceans, snow and ice, and energy budget. Each sensor has unique features that enable scientists to meet a wide range of science objectives. The five Terra onboard sensors are:

  • ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer)
  • CERES (or Clouds and Earth’s Radiant Energy System)
  • MISR (Multi-angle Imaging SpectroRadiometer)
  • MODIS (Moderate-resolution Imaging Spectroradiometer)
  • MOPITT (Measurements of Pollution in the Troposphere)

Because all five instruments are on the same satellite making simultaneous observations, scientists are able to compare different aspects of Earth’s characteristics over time.
