New output for 2019 is available for all stations. The files are generated from a GMI chemistry transport model (CTM) simulation integrated with MERRA2 reanalysis meteorology – the same version as used for 1985-2018 files. All files can be downloaded via anonymous ftp from ftp://ftp.cpc.ncep.noaa.gov/ndacc/gmi_model_data.

The ASOPOS (Assessment of Standard Operating Procedures for OzoneSondes) Panel, a group of ~20 ozonesonde expert data-providers, was formed in 2004. ASOPOS, under WMO/GAW sponsorship, has issued periodic reports on ozonesonde quality assurance, including evaluations of sonde intercomparisons in the Juelich Ozonesonde Intercomparison Experiment (JOSIE) series. The report documents include the WMO/GAW Report 201 on ozonesonde standard procedures (Smit
The Assessment of Standard Operating Procedures for OzoneSondes (ASOPOS) 2.0 Panel held a remote meeting from 18-20 March 2020. ASOPOS is compiling results from laboratory, field, and pressure chamber experiments to communicate the latest knowledge and best practices for the operation of electrochemical concentration cell (ECC) ozonesondes, a key component of the NDACC network. The panel is assembling a new WMO/GAW Report to update WMO/GAW Report No. 201, which can be found HERE.
