MONITORING OF AEROSOL OPTICAL PROPERTIES, TOTAL COLUMN OZONE CONTENT, AND SOLAR UV-B ERYTHEMAL IRRADIANCE OVER THE KISHINEV

Abstract

Results of the aerosol optical properties, total column ozone content and UV-B erythemal irradiance measurements carried out at the ground-based station over Kishinev, Moldova are presented. Simultaneous observations were performed with a sunphotometer Cimel-318, hand-held ozonemeter MICROTOPS II and UV-B broadband sensors which are a part of radiometric complex. Station was incorporated into the globally distributed Aerosol Robotic Network (AERONET), managed by NASA/GSFC. Spectral aerosol optical thicknesses retrieved from sunphotometer measurements throughout the period of 1999-2003 are presented. One year measurements of total column ozone carried out at the station are presented in comparison with the multi-year statistics retrieved from Earth Probe Total Ozone Mapping Spectrometer satellite platform measurements. Seasonal variation of monthly totals and diurnal variations of global and diffuse components of solar UV-B erythemal irradiances measured at the Kishinev site are presented.
