|"Four Decades of Ozone Measurement from Space: Effects of clouds and aerosols on UV radiation"
Pawan K. Bhartia, NASA Goddard Space Flight Center
Abstract: Next month will mark the 42nd anniversary of the launch of the BUV instrument on Nimbus-4 satellite that started long-term measurement of ozone column and vertical profile from space. In this talk I will focus on total ozone, which is currently one the best-measured atmospheric variables from space, with accuracies now exceeding best ground-based techniques. To achieve this we had to develop detailed understanding of how aerosols and clouds affect UV radiation, a field that has been largely ignored by the radiation science community. I will describe recent results that show that even after decades of work this field is far from exhausted.
