REMOTE SENSING: ATMOSPHERE

With the aim of characterising the physical and chemical properties of the atmosphere, we develop new observational methods, new active and passive instruments, field measurements, models and algorithms for the extraction of geophysical parameters from the acquired data.

In particular, we design and fabricate:

  • Fourier transform spectroradiometers operated in the mid and far infrared spectral regions, and used in field campaigns from ground and stratospheric platforms for the measurement of atmospheric composition and radiance;
  • LIDAR systems for the characterization of clouds and atmospheric aerosol, both in metropolitan areas and on remote sites such as Dome-C in Antarctica;
  • asset systems for the control of stratospheric gondolas, used in experiments of both Earth observations and cosmology;
  • numerical codes for level 2 analyses of space observations of the atmosphere for the three-dimensional reconstruction of atmospheric composition and for the monitoring of greenhouse gasses;
  • methods for the study of the morphology of the ionosphere and for the determination of its total electron content.

IFAC has contributed to a series of projects hosted such as MIPAS-ENVISAT, SAFIRE, REFIR by ASI and MARSCHALS, CAMELOT, KLIMA, MIPAS-ENVISAT by ESA. The results can be applied to quality air monitoring and to the study of atmospheric chemistry and climatic changes.
