Aristotle University of Thessaloniki (AUTH)

AUTH is the largest University in Greece with more than 70000 students and covers a very large number of scientific disciplines. The Laboratory of Atmospheric Physics (LAP) belongs to the Physics Department and consists of 5 permanent senior academic scientists, 5 post-doc and 8 PhD students. AUTH operates two Brewer spectrophotmeters for the monitoring of total ozone already since the 80s, has recently developed its own Max-DOAS instrument. It operates a UV-B monitoring network in Greece and hosts the WMO Ozone Mapping Centre for the Northern Hemisphere, which receives daily in real-to-real time preliminary total ozone data from around 100 ground based total ozone observing stations. AUTH hosts the GOME-2 validation site within EUMETSAT’s O3MSAF. LAP has its own air quality modelling team and has developed its own computer and storage facilities.

The Laboratory of Atmospheric Physics of the Aristotle University of Thessaloniki (AUTH) has long experience in performing spectral measurements of solar irradiance and sky radiance in the UV-VIS spectral region. AUTH has participated in many major laboratory and field intercomparison campaigns for solar UV radiation during the last 20 years aiming at improving our ability to accurately determine the UV-VIS spectrum at the Earth’s surface, using commercial and self-developed instruments. Recently, AUTH has developed a mini DOAS system for total and tropospheric NO2 column measurements working closely with IASB-BIRA for the retrieval and validation of products. Currently is working on improving the capabilities of the existing system aiming at the development of 2 new systems. AUTH is involved in the validation of ozone, SO2 and aerosols from satellites (GOME, OMI, GOME-2, TOMS-EP) and is member of EARLINET, the first aerosol lidar network established.

Main tasks
The main tasks of AUTH within the project are: Study of the temporal and spatial variability of SO2 based on satellite data. Estimate the SO2 emissions. Perform tropospheric NO2 measurements using its own MAX-DOAS instrument in China and validate satellite tropospheric NO2. Validation of total ozone from the FY missions.
