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.

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 ...

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, and will be comparable locally, and globally. Eleven Dobson Spectrophotometers from different monitoring and research institutions in Latin America were calibrated during the campaign. The associated relative uncertainty of each Dobson was also estimated.

HYDROMET GAP REPORT 2021
The Country Hydromet Diagnostics responds to the need for a standardized, integrated and operational tool and approach for diagnosing National Meteorological Services, their operating environment, and their contribution to high-quality weather, climate, hydrological and environmental information services and warnings. The Diagnostics is an umbrella tool that draws on and adds value to existing WMO assessment material by synthesizing existing approaches and data into an easily interpretable form, validating the information provided by WMO Members through a peer review process, and obtaining mis ...

IOM Report, 134. Report on Interlaboratory Comparison in the field of Temperature, Humidity and Pressure in the WMO Regional Association II, V and VI (MM-ILC-2018-THP-2)
WMO, 2021This report presents the results of an interlaboratory comparison (ILC) with participation of all Regional Instrument Centres (RICs) in WMO Regional Associations (RAs) II and V, using the methodology and experience from the ILC in RA VI in 2016. The ILC was coordinated by RIC Tsukuba (Japan) with support and input from RIC Ljubljana and the University of Ljubljana, Faculty of Electrical Engineering (Slovenia). The results of the ILC in RA II and RA V clearly demonstrate the high capabilities of these RICs, particularly in the domains of temperature and humidity calibration. Some areas requirin ...

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 ...
