GAW Report, 280. Fifth WMO Filter Radiometer Comparison (FRC-V) 27 September to 25 October 2021 Davos, Switzerland (GAW 280)
World Meteorological Organization (WMO) ; Stelios Kazadzis, Natalia Kouremeti, Julian Gröbner - WMO, 2023The Fifth Filter Radiometer Comparison (FRC-V) was held with one year of delay due to COVID-19 pandemic and relative restrictions, concurrently with the 13th International Pyrheliometer Comparison in Davos, Switzerland. Instrumentation belonging to different AOD global networks were invited and participated. Also, three reference instruments from the Calibration of Aerosol Remote Sensing (CARS) of the pan-European research infrastructure ACTRIS (Aerosol, Clouds and Trace Gases Research Infrastructure) facility participated. The comparison took place at the premises of PMOD/WRC from September 2 ...

Published by: WMO ; 2023The Fifth Filter Radiometer Comparison (FRC-V) was held with one year of delay due to COVID-19 pandemic and relative restrictions, concurrently with the 13th International Pyrheliometer Comparison in Davos, Switzerland. Instrumentation belonging to different AOD global networks were invited and participated. Also, three reference instruments from the Calibration of Aerosol Remote Sensing (CARS) of the pan-European research infrastructure ACTRIS (Aerosol, Clouds and Trace Gases Research Infrastructure) facility participated. The comparison took place at the premises of PMOD/WRC from September 27th to October 25th, 2021. Thirtytwo (32) filter radiometers and spectroradiometers from 12 countries participated in this campaign.
The objective of this campaign was to compare aerosol optical depth and Ångström exponents (AE) derived from different instruments belonging to different global, regional or national networks in order to quantify the main factors that are responsible for possible deviations. The aim of the whole activity was to initiate action towards homogenization of the AOD measurements on a global scale. The comparison protocol was formulated according to the WMO recommendations. Measurements of each instrument were compared to the WORCC Precision Filter Radiometer (PFR) reference triad.Collection(s) and Series: GAW Report- No. 280

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 ...
