Science Update: Interannual stratospheric ozone variability at Mauna Loa, Hawaii, and Table Mountain, California.

G. Kirgis and co-authors recently published a paper in ACP regarding the interannual variability of stratospheric ozone at Mauna Loa, Hawaii, and Table Mountain, California. They used a multi-linear regression analysis on monthly mean lidar and satellite profile data between 20-45km from the volcanically quiescent period of January 1995 to April 2011. Results were consistent with recent model simulations indicating changes in tropical upwelling. They found a net increase and sign of ozone recovery after 2005. Find the full abstract here.
