Questions and Answers

What is typically measured by microwave radiometers?

  • The thermal radiation of the atmosphere (correct)
  • The temperature profiles of the upper troposphere
  • The emission of microwave radiation of atmospheric trance gases
  • The thermal radiation of the atmosphere and ice

What information can be inferred from the measurement of thermal radiation of the atmosphere?

  • Temperature profiles of the lower troposphere (correct)
  • The emission of microwave radiation of atmospheric trance gases
  • Temperature profiles of the upper troposphere
