Attention:
Please note that operations of the Fast Greenhouse Gas Analyser requires experienced scientific staff on board the aircraft.
Summary
The Greenhouse Gas Analyzer (model GGA-24EP) is an advanced instrument for simultaneous measurements of methane (CH4), carbon dioxide (CO2) and water vapor (H2O) using cavity enhanced laser absorption technique.

Rawdata storage on board
During flight FGGA data are stored within the rack unit. Analog data of the methane concentration are also stored within the DMS system.
Data archiving on land
After the flight FGGA data have to be downloaded and are stored within the external devices file system of the aircraft data managment system (DMS).
