Measurement Details

In 2005 the German Remote Sensing Data Center (DLR-DFD) developed and put the GRIPS 4 (Ground-based Infrared P-branch spectrometer) into operation. It is the mobile version of the GRIPS 3 instrument (see Schneefernerhaus site) and has since then been operated once on the German Research Vessel “Polarstern” during the expedition ANT XXIII/1 in 2005 and twice at the German Environmental Research Station “Schneefernerhaus” during the SCARAMANGA campaigns in 2006 and 2008. In the meantime it is located at DLR in Oberpfaffenhofen and measures the OH airglow next to GRIPS 6, which has been installed in January 2009 and is in fully automatic operation since February 2009.

GRIPS 4 has a variable field of view (zenith looking in Oberpfaffenhofen) and covers the spectral range from 1520 nm to 1550 nm during standard operation. It is equipped with a liquid nitrogen cooled Germanium detector and has a temporal resolution between two and three minutes. GRIPS 5 is a solely zenith looking spectrometer with a thermoelectrically cooled InGaAs-Array covering the spectral range between 1500 nm and 1600 nm.
