Comparison of stratospheric AOD from MERRA-2 and available observational reconstructions. (a) MERRA-2 AOD (monthly mean) computed for the portion of the atmospheric column above the model tropopause and where AVHRR observations are available. (b) AVHRR AOD anomaly computed by subtracting from the post-Pinatubo AVHRR AOD a 7-yr climatology of AVHRR AOD less affected by major volcanic eruptions (climatology computed for 1986–90 plus 1995–96 AVHRR AOD), (c) MERRA-2 AOD computed for the portion of the atmospheric column above the model troposphere and where SAGE II extinction profiles were available. (d) Reconstructed SAGE II stratospheric AOD from Thomason and Peter (2006) and L. Thomason (2016, unpublished manuscript).
