He doesn't wear a cape, he's 25 years old and watches over our skies. It's VAG Ushuaia, our Global Atmospheric Surveillance Station. We'll tell you what he's taking care of.
In the movies, superheroes wear disguises, have superpowers and fight against some villain. Our End of the World Watcher doesn't need the mask. His secret weapons are science, perseverance and balloons, many balloons. His archenemy is the most dangerous of all, the fearsome climate change. That's why VAG Ushuaia, our Global Atmospheric Surveillance Station, fights not just for us, but for the whole planet.
The Ushuaia Global Atmospheric Surveillance Station, better known by its acronym VAG, is located on the shores of the Canal Mr. Beagle. He has turned 25 years at the service of our planet, studying both atmospheric gases, greenhouse gases, ozone and aerosols. All key pieces in research on climate change, ozone hole and solar radiation linked to UV rays. Although our Vigilante works in a desolate place, he is not alone, as he is part of a network of 30 stations international. Thus, the information collected is extremely valuable. It allows us to know the situation of our atmosphere and is used to issue recommendations for responsible care of the environment environment.
At VAG Ushuaia Station, ozone is permanently measured every day of the year using three different equipment: a spectrophotometer, a dobson and by means of ozone soondes. This last measurement is the most accurate and the most beautiful as well. It is performed using a balloon with helium gas that rises in the atmosphere to a height of 50 kilometers. Ozone soonings with balloons are performed from August to December once a week and, in the months where the hole is opened, the frequency is increased up to three times a week. It is an unmatched spectacle that Station scientists kindly engage in sharing through their social networks.
The information collected by the Ushuaia VAG Station also has direct effects on our daily lives - Yeah . All data obtained are used for research, projects and newsletters issued by the World Meteorological Organization and the National Meteorological Service. So, every time you beat a storm by hand or wear the right clothes for the temperature
