Learjet IMECC campaign

On behalf of MPI for Biogeochemistry Jena enviscope successfully finalized a flight campaign to validate ground based Fourier-transform infrared (FTIR) spectrometers measuring the total column of CO2 and CH4 at high accuracy. The Learjet 35A D-CGFD was instrumented with a Cavity Ringdown System for CO2, CH4 und H2O, a CO analyser and a flask sampler. Spiral flights at the stations Byalystok (Poland), Trainou (France), Bremen, Garmisch-Partenkirchen, and Jena (Germany) were performed between FL420 and the boundary layer.
