AirYX SkySpec

AirYX SkySpec

A low-effort, efficient and reliable telescope-spectrometer system for remote sensing of atmospheric particles and gas

  • Telescope-spectrometer systems for direct-sun and scattered skylight spectrum acquisition
  • Optimized for DOAS (Differential optical absorption spectroscopy) observations
  • Detectable gases: NO₂, O₃, SO₂, HCHO, H₂O, HONO, IO, BrO, Glyoxal, O₄
  • Modular systems with customisable configurations

How it works

Perform low-effort, efficient and reliable atmospheric observations with the Passive DOAS (Differential Optical Absorption Spectroscopy) method (according to VDI standard 4212).

The measurements provide information on the tropospheric and stratospheric concentration and distribution of various trace gases, e.g. NO₂, SO₂,formaldehyde, and aerosol optical depth. Also other high precision spectroscopic applications are possible like surface reflection spectroscopy.

The covered spectral range and resolution of the instruments can be customised and adapted to the needs of the user. With our long experience of several decades in spectroscopy we optimise spectrometer configurations and setups to achieve best possible measurements with highlight throughput and best achievable noise level. Besides the single spectrometer configuration we also offer a double spectrometer system to cover a larger spectral range with optimum spectral properties.

Typical applications

  • Passive DOAS especially MAX (Multi Axis) – DOAS measurements of NO₂, SO₂, HCHO (and others)
  • Direct Sun DOAS measurements, retrieval of stratospheric and tropospheric total columns of various gases
  • Application on mobile platforms e.g. ships
  • Air quality monitoring and trace gas measurements in urban, rural and pristine environments
  • Emission plume studies of e.g. power plants, industrial complexes or volcanoes
  • Total flux measurements of e.g. NO₂, SO₂, HCHO of power plants, industrial complexes, cities or volcanoes
  • Scientific studies involving measurements of NO₂, SO₂, HCHO, HONO, H₂O, Glyoxal, BrO, IO, Ozone
