Methane Airborne Mapper (MAMap): A new airborne two channel NIR-SWIR grating spectrometer system for simultaneous remote measurements of tropospheric methane (CH4), carbon dioxide (CO2) and oxygen (O2) — •Konstantin Gerilowski1, Andreas Tretner2, Michael Buchwitz1, Jörg Erzinger2, John Phillip Burrows1, and Heinrich Bovensmann2 — 1Institute of Environmental Physics / Remote Sensing (IUP/IFE), University of Bremen, Bremen, Germany — 2GeoForschungsZentrum Potsdam (GFZ), Potsdam, Germany
Beginning in summer 2005, the IUP Bremen and the GFZ Potsdam developed a new type of airborne two channel SWIR-NIR grating spectrometer system, the ''Methane Airborne Mapper'' (MAMap). From the experience gained with SCIAMACHY, this instrument is capable of direct and quantitative nadir remote measurements of atmospheric methane (CH4) and carbon dioxide (CO2). It covers important parts of the short wave infrared (SWIR)/ near infrared (NIR) spectral windows (around 1600 nm, 1660 nm and 760 nm) for simultaneous detection of CH4, CO2 and O2. The instrument has been designed for flexible operation on board of different airborne research platforms (e.g. Chessna Caravan, DLR Dornier 228, DLR Falcon and the future DLR Gulfstream ''HALO'' aircraft). Different laboratory and ground based measurements have been performed demonstrating the instrument's performance. Preliminary ''in-flight'' measurements will also be presented.
