Travelling reference spectrometer developed for the Network for Detection of Mesospheric Change

Posted on Posted in Atmospheric ECVs, Updates

A travelling reference spectrometer (TRSP) implemented in the traceability concept developed for the Network for Detection of Mesospheric Change (NDMC) within the EMRP project ENV53 MetEOC2 (D2.2.1 to D2.2.13) has reached one year of simultaneously successful operation.

It continues operation alongside another Ground-based infrared P-branch spectrometer (GRIPS) at the Oberpfaffenhofen NDMC, for determining Mesosphere’s temperature traceable to the SI.

Also, several GRIPS instruments from DLR were improved according to the concept developed in MetEOC2 for the TRSP to minimise thermal drifts and straylight.
