Measurements at Maïdo Observatory

The Maïdo atmospheric observatory is located on Reunion Island at an altitude of 2200 m, at a distance of about 22 km from the St. Denis TCCON site.  A great number of different instruments are deployed at the Maïdo observatory, including a second FTIR spectrometer operated by the Royal Belgian Institute for Space Aeronomy.

A detailed description of the Maïdo station and its instruments can be found in this AMT paper: http://www.atmos-meas-tech.net/6/286...2865-2013.html

Instruments currently deployed at Maïdo:

  • Rayleigh-Mie Lidar: Temperature 10 - 90 km (NDACC)
  • Raman Lidar: Water 2 - 17 km (NDACC)
  • DIAL Lidar: Ozone 6-17 km and 15-45 km (NDACC)
  • Doppler Lidar: Wind 5 - 50 km
  • Microwave radiometer: Water 15 - 75 km
  • Lightning sensor (WWLLN)
  • CPC 3775 Particle counter (GAW)
  • Chemical filters: Aerosol chemistry (GAW)
  • GPS receiver: Water total column (IGS)
  • FTIR (NDACC)
