Discrepancies between expected and observed NO-NO2 ratios in the upper troposphere suggest the presence of an unknown NOX reservoir. We report on airborne remote sensing limb observations from the mini-DOAS instrument on board the HALO (High Altitude

The increase of atmospheric methane (CH4) and carbon dioxide (CO2), two of the main anthropogenic greenhouse gases, is largely driven by fossil sources. Sources and sinks remain insufficiently characterized in the Mediterranean and Middle East areas,
