Science update: Diurnal variability of stratospheric ozone measured at Mauna Loa

In a recent ACPD article, A. Parrish and co-authors use microwave observations from the Mauna Loa NDACC station to investigate the diurnal variation of stratospheric ozone. They compare these microwave observations with satellite measurements from Aura-MLS, UARS-MLS, SMILES and SBUV/2, as well as with output from the GEOSCCM chemistry climate model. The measurements agree with the model to better than 1.5% in most cases except the morning-night differences, which are significantly higher in the observations (2-3% from ~39-43km).
