OZONE MONITORING PROJECT AT "ARTIGAS"
Listed in NASA Earthdata CMR
Ozone depletion, first detected in the 1970s and generally greater at higher latitudes in winter and spring, has formed a hole that could be as big as the U.S. area and as deep as 66% loss of total ozone.
Description
Ozone concentration and Ultra-Violet B radiation (UV-B) are inversely related, where a decrease in ozone concentrations usually results in an increase of UV-B reaching the earth surface. This increase of UV-B radiation is totally harmful for the live beings and for the climatic system.
As a result, the scientific international community, concerned about this global phenomenon, has been doing many efforts on measuring, studying and understanding the evolution of this layer. From 1998, Uruguay cooperates with the World Ozone and Ultra Violet Data Center, installing a Brewer MKII spectrophotometer at Artigas Uruguayan Antarctic Scientific Base (62�11'04''S - 58�54'09''W, 17.2 meters over MSL), adopting its geographical name King George Island, number 351.

This project is carried out by the cooperation of three Official Institutions of Uruguay: Uruguayan Antarctic Institute (UAI), Ministry of Housing, Territorial Regulation and Environment and the Uruguayan Air Force Meteorological Service; being the first of the noted, the focal point for national contact. The Uruguayan Antarctic Ozone Project, inserted within a National Antarctic Policy, consists on taking measurements of total ozone, UV-B radiation, and umkehr (ozono profile), forecasting UV-B radiation (through a signed agreement between the UAI and the Spain Meteorological Institute Iza�a Atmospheric Laboratory, economically supported by the Canarias Goverment), intercomparing Brewer and satellite measurements, contributing with national, regional and worldwide programs (exchanging data) and supporting scientific activities developed within the Antarctic Treaty.
