Sun/Moon photometer for Cherenkov Telescope Array – first results

Popis výsledku v původním jazyce

Determination of the energy and flux of the gamma photons by IACT is strongly dependent on optical properties of the atmosphere. Therefore, atmospheric monitoring during the future observations of the CTA as well as anticipated long-term monitoring in order to characterize overal properties and annual variation of atmospheric conditions are very important. Several instruments are already installed at the CTA sites in order to monitor atmospheric conditions on long-term. One of them is a Sun/Moon photometer CE318-T, installed at the Southern CTA site. Since the photometer is installed at a place with very stable atmospheric conditions, it can be also used for characterization of its performance and testing of new methods of aerosol optical depth (AOD) retrieval, cloud-screening and calibration. In this work, we describe our calibration method for nocturnal measurements and the modification of cloud-screening for purposes of nocturnal AOD retrieval.
