Ground-Based FTIR Remote Sensing





The group performs ground-based remote sensing of the composition of the atmosphere. Mainly with ground-based FTIR (Fourier-Transform Infrared Spectrometer) observations, profiles and column abundances of several trace gases are measured. The main objectives are to record short-term variability and long-term trends of ozone related species and greenhouse gases, and to validate satellite data. These measurements are made within the framework of:

  • COCCON (COllaborative Carbon Column Observing Network),
  • NDACC (Network for the Detection of Atmospheric Composition Change) and
  • TCCON (Total Column Carbon Observation Network).

These measurements include:

  • a network of compact FTIR spectrometers operated in the NIR to measure greenhouse gases, mainly CO2 and CH4 (COCCON),
  • high-resolution FTIR spectrometers to measure several trace gases like O3, HCl, HF, ClONO2, HNO3, N2O, CH4, CO, C2H6, and HCN (see FTIR sites for more details),
  • remote sensing of water isotopologues from multiple platforms, mainly of HD16O (MUSICA),
  • remote sensing with millimeter wave radiometry (MWR). MWR allows us to retrieve profiles, for example of O3 and CO, up to an altitude of about 60 km.

Information on the software used for the spectrometer and data evaluation is available here.
