Remote sensing using aircraft and balloons

Welcome to the FFB homepage

B2_F10_020212_49.jpgThe group FFB develops and operates limb-sounding FTIR spectrometers on balloon and aircraft platforms to measure vertically resolved distributions of temperature, water vapour and a wealth of trace gases (e.g. ozone, CH4, N2O, CFCs, HCFCs, HNO3, ClONO2, NO2, HNO4, CCl4, CF4, C2H6, SF6, OCS, SO2) and their isotopologues (e.g. HDO) in the Earth’s atmosphere.

Limb-scanning instruments like the balloon- and airborne- versions of MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) have been deployed in numerous measurements campaigns from the Arctic to the Antarctic since more than 20 years.

HaloThe most recent development of the group is the imaging FTIR spectrometer GLORIA (a common project between KIT and the Research Center Jülich) which has successfully been operated on the Russian aircraft M55 Geophysica and the German research aircraft HALO.

GLORIA is the first infrared limb-emission-imager with high spectral resolution to probe the state of the atmosphere with exceptional spatial resolution. As such it serves as pathfinder and showcase for possible future space-borne instruments.

GeophysicaA further focus of FFB is the characterisation of the spectrometric and radiometric performance of imaging spectrometers and the development of algorithms to exploit the data generated by the instruments. In this field the group closely cooperates with space agencies and space industry to advance the use of IFTS from space.
