Ralf Zuber et al. on the validation of a new array spectroradiometer: A measurement system consisting of two array spectroradiometers, a UV-BTS and a VIS-BTS was set up, to achieve a wavelength range from 200 nm to 1050 nm. This system has been compared with the NDAC travelling UV spectroradiometer, which id a double monochromator-based device that complies to the NDACC specifications at a measurement campaign for spectral global irradiance with the aim to validate an array spectroradiometer as well with the stated NDACC specifications.
The annual meeting of the international Steering Committee (SC) for NDACC was held 10-14 September 2018 in Geneva, Switzerland at the headquarters of the World Meteorological Organisation (WMO). Geir Braathen of WMO hosted the meeting.
The second SPARC/WMO Long-term Ozone Trends and Uncertainties in the Stratosphere (LOTUS) workshop took place in Geneva, September 17-19, 2018 (https://events.oma.be/indico/event/56/overview).
About 30 participants gathered to discuss open issues remaining after publishing the SPARC/WMO LOTUS report that was aimed at providing timely input to the 2018 Ozone assessment.
SHADOZ (an NDACC Cooperating Network) data have been re-processed over the past 2-3 years with four papers documenting the activity and evaluating changes in the data and uncertainties as follows. You may be able to download some of the articles directly from the publisher. Otherwise, all are downloadable at the website: https://tropo.gsfc.nasa.gov/shadoz/SHADOZ_PubsList.html .
Model outputs generated by the Theory and Analysis Working Group are now available as netCDF files for individual stations from 1985-2017. They can be downloaded via anonymous ftp at the website ftp://ftp.cpc.ncep.noaa.gov/ndacc/gmi_model_data. The files are generated from a GMI chemistry transport model (CTM) simulation integrated with MERRA2 reanalysis meteorology. They have realistic constituent variability from daily to seasonal timescales.
