For the first time we report on ground-based lidar observations of the same event from every continent in the Northern Hemisphere, taking advantage of the synergy between global lidar networks such as EARLINET, MPLNET and NDACC with independent lidar groups and satellite CALIPSO to track the evolution of the stratospheric aerosol layer in various parts of the globe. The globally averaged aerosol optical depth (AOD) due to the stratospheric vol- canic aerosol layers was of the order of 0.018±0.009 at 532 nm, ranging from 0.003 to 0.04. Compared to the total column AOD from the available collocated AERONET stations, the stratospheric contribution varied from 2% to 23% at 532 nm.}, organization = {NNX10AR38G (DISCOVER-AQ)}, organization = {NASA Earth Observing System and Radiation Sciences Program}, organization = {National Key Basic Research Project of China 2007FY110700}, organization = {Universidad de Granada CGL2010-18782, P10-RNM-6299}, organization = {EU FP7 Project ‘ACTRIS’}, organization = {Ministry of Earth Sciences, India}, organization = {Natural Environment Research Council, UK}, organization = {CNRS INSU}, publisher = {IOP Science}, title = {Stratospheric AOD after the 2011 eruption of Nabro volcano measured by lidars over the Northern Hemisphere}, doi = {10.1088/1748-9326/7/3/034013}, author = {Sawamura, P and Vernier, J.
