In July 2017 and March 2018, the mobile NDACC reference lidar from NASA GSFC took part in an intercomparison campaign for stratospheric ozone and temperature profiles at the Observatoire Haute Provence in Southern France. Here we report on the initial comparison of
1.) ozone profiles from the NASA lidar, the stratospheric ozone lidar at Haute Provence, ECC sondes, the tropospheric ozone...

The overview of recent new activities related to LOTUS at Finnish Meteorological Institute will be presented.
First, the long-term merged dataset with resolved longitudinal structure, which is developed in the framework of ESA Ozone_cci project, will be presented. The dataset includes the data from GOMOS, MIPAS, SCIAMACHY and OSIRIS; it covers the years from 2002 to present. The dataset...

A continuous monitoring of the stratospheric ozone layer over a global scale is done by means of several techniques. Observations in limb geometry from satellite platforms provide ozone profiles with a good vertical resolution, spatial and temporal coverage.
SCIAMACHY and OMPS-LP are two satellite instruments able to collect shortwave scattered radiance in limb geometry. Ozone profile data...

With the rationalisation of climate data sets brokered from data providers through portals like the C3S Climate Data Store (CDS) and NASA GES-DISC, a key element of quality assurance is the provision of traceable uncertainty information. In important climate data records like total column ozone and ozone vertical profile data sets, ideally one would like uncertainties to be traceable back to a...

A lot of effort has been put into acquiring, post-processing, and constructing composite timeseries of ozone observations. It is well documented that much of the uncertainty in long term ozone trends stems from the methodologies applied. Further, often composites lack comparable uncertainties and typically are not independent of each other. These issues lead to difficulties in gaining an...
