A ground-based spectrometer equipped with an InGaAs array for routine observations of OH(3-1) rotational temperatures in the mesopause region

A fully automated data acquisition and analysis scheme has also been developed, that covers the complete processing chain from data recording to derivation of rotational temperatures and to long-term archiving. For the estimation of a nocturnal mean value all samples of the nightly temperature time series are weighted according to their individual precision. Thus, mean temperatures between 1 and 2 K are lower compared to the unweighted arithmetic mean. Data products are archived at the World Data Center for Remote Sensing of the Atmosphere (WDC-RSAT) and results are displayed at the website of the Network for the Detection of Mesosphere Change (NDMC). A summary of the data obtained during the first 40 months of operation at the German Remote Sensing Data Center as well as aspects of data processing efforts are presented.
