World Meteorological Organization (WMO) ; Agencia Estatal de Meteorología (España) ; Fourteenth Intercomparison Campaign of the Regional Brewer Calibration Centre Europe (El Arenosillo Atmospheric Sounding Station, Huelva, Spain, 17–28 June 2019)
Published by: WMO, AEMET ; 2021XIV Regional intercomparison of the Brewer Calibration Center for Europe (RBCC-E) was held at El Arenosillo Atmospheric Sounding Station of the “Instituto Nacional de Técnica Aeroespacial” (INTA) during the period 17 – 28 of June, 2019. 21 Brewer spectrometers, 15 operators and experts from 11 countries took part in XIV Regional intercomparison campaign. The campaign was organized in collaboration with the “Area of Instrumentation and Atmospheric Research” of INTA, with the support of the Global Atmospheric Watch (GAW) program of the World Meteorological Organization (WMO). The Brewer travelling instrument from the Regional Brewer Calibration Center - Europe served as ozone reference and the QASUME unit from the World Calibration Center provided the UV calibration for the participating instruments.
The main goal of the campaign was to transfer the calibration from the reference standard to the participating instruments and to compare the instruments which are also reference standards for individual networks or are used as travelling standards and included Environment and Climate Change Canada, International Ozone Services Inc. (OS), Kipp and Zonnen Inc., and Japan Meteorological Agency.
The results of the blind comparison (using the instruments’ original calibration constants) are In agreement with previous campaigns, 6 instruments show an agreement better than 0.5%, which represent (31%) of the participating instruments. Of the remaining instruments, 74% show an agreement inside the 1% range. After the maintenance tasks, performed by International Ozone Services Inc. (IOS), and using the new determined calibration constant and the stray light correction applied to single monochromator Brewers, the agreement with respect to the reference was very good: +/- 0.5%.Collection(s) and Series: GAW Report- No. 257

GAW Report, 267/Research Infrastructure Quality Assurance. Fifth International Comparison of Dobson Spectrophotometers Villa Ortúzar Observatory, Argentina, 4-22 March 2019
World Meteorological Organization (WMO) ; Glen McConville, Koji Miyagawa, and Gerardo Carbajal Benítez - WMO, 2021This report describes the Fifth Intercomparison of Dobson Spectophotometers (IC/BUA-19) carried out at the Main Buenos Aires Observatory (Villa Ortúzar) of the Servicio Meteorológico Nacional (Argentina) (SMN) from 4 March to 22 March 2019. The Dobson spectrophotometer D065 was used as a reference for comparison of measured ozone column values and to calibrate individual instruments. The Regional Standard (R-III) also participated in the event and was calibrated. Through this activity, the data obtained by individual Dobson Spectrophotometers at different measurement sites will be standardized ...

Report on the Unexpected Emissions of CFC-11 (WMO-No. 1268)
The Report was written by the Scientific Assessment Panel to the Montreal Protocol on Substances that Deplete the Ozone Layer. CFC-11 (CCl3F) was reportedly fully controlled under the Montreal Protocol since 2010. However, a 2018 scientific paper revealed that instead of decreasing, CFC-11 emissions were increasing. In reaction, the Protocol parties agreed to Decision XXX/3: Unexpected emissions of trichlorofluoromethane (CFC-11). This Report addresses: current and past observations of CFC-11 atmospheric abundances; information on the CFC-11 global and regional emission increase and subsequent ...

GAW Report, 266. System and Performance Audit of Surface Ozone, Carbon Monoxide, Methane, Carbon Dioxide and Nitrous Oxide at the Global GAW Station Zugspitze-Schneefernerhaus Germany, September 2020
World Meteorological Organization (WMO) ; C. Zellweger, M. Steinbacher, B. Buchmann, R. Steinbrecher - WMO, 2021The 6th system and performance audit by WCC-Empa at the global GAW station Zugspitze-Schneefernerhaus (ZSF) was conducted from 8 - 9 September 2020 in agreement with the WMO/GAW quality assurance system. This report summarises the assessment of the Zugspitze-Schneefernerhaus GAW station in general, as well as the surface ozone, methane, carbon dioxide, carbon monoxide and nitrous oxide measurements in particular. The recommendations found in this report are graded as minor, important and critical and are complemented by a priority indication and a suggested completion date.
