SIG 5: Astronomy and Earth Observation

The Special Interest Group (SIG) for Astronomy and Earth Observation brings together researchers, technologists, and industry partners to explore the exciting potential of THz science and technology in applications for astronomy and Earth observation. This SIG will cover a wide range of topics, including instrumentation and detector development, atmospheric and environmental sensing, ground and space-based THz astronomy, data processing techniques, and emerging applications in Earth observation.

Our aim is to foster collaboration across disciplines, bridging the gap between fundamental research and applied technologies. By creating a platform for knowledge exchange, we seek to accelerate innovation in THz systems that can unlock new insights into the universe and improve monitoring of our planet’s climate.

The group is keen to engage with academia, industry, and government agencies, encouraging participation from experts in physics, engineering, astrophysics, remote sensing, and data science. We welcome discussions on new ideas, disruptive technologies, and novel approaches, with a particular focus on advancing instrumentation, improving measurement accuracy, and addressing challenges in deployment for space and Earth based missions.

Through regular meetings, workshops, and collaborative projects, we aim to establish a vibrant community that drives progress in THz science and its applications. By sharing expertise and resources, the SIG will help shape the future of THz astronomy and Earth observation, delivering solutions that benefit both scientific discovery and societal needs.

Specific research areas include:

  • THz heterodyne spectrometers for planetary atmosphere analysis
  • Submillimeter observation of star and galaxy formation
  • THz polarimetry for cosmic microwave background studies
  • Instrumentation for Astronomy (ground and space-based)
  • Atmospheric transmission
  • Remote sensing of atmospheric gases (e.g., ozone, water vapor) using THz bands
  • THz radar and lidar for high-resolution Earth surface monitoring
  • THz receivers for space telescopes
  • Development of ultra-sensitive cryogenic bolometers and superconducting mixers
  • THz spectroscopic analysis of interstellar dust and molecular clouds
  • Planetary science instrumentation for space missions
