Methane Airborne MAPper (MaMAP): A new airborne 2 channel NIR-SWIR grating spectrometer system for simultaneous remote measurements of tropospheric methane (CH4), carbon dioxide (CO2) and oxygen (O2)
A joint research project of Institute of Environmental Physics / Remote Sensing (IUP/IFE), University of Bremen, Germany (K. Gerilowski, M. Buchwitz, H. Bovensmann, J. P. Burrows), Geoforschungszentrum Potsdam (GFZ), Potsdam, Germany (A. Tretner, J. Erzinger)


ENVISAT satellite level-1 validation by radiometric calibration of balloonborne and airborne spectrometers
A complicated title for a very straightforward idea: The SCIAMACHY spectrometer onboard the european ENVISAT (Environmental Satellite) measures atmospheric trace gas concentrations from space. Our project uses similar spectrometers that are deployed on balloonborne and airborne missions up to 32 km altitude to cross-check the photometric readings made by the satellite instrument, before these are converted to trace gas data. This validation assures consistent data quality of the satellite measurements.


ENVISAT satellite level-2 validation by measurement of atmospheric trace gas profiles using the balloonborne CHILD (Compact High-altitude In-situ Laser Diode) spectrometer
The aim of the project is the validation of SCIAMACHY H2O and CH4 profiles by an independent technique. Validation measurements of H2O and CH4 are made in-situ from ground to more than 30 km altitude by the lightweight CHILD-TDL spectrometer flying piggyback with the TRIPLE balloon payload. Additional applications of CHILD are atmospheric chemistry and climate studies.
