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.

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

Bulletin de l'OMM sur les gaz à effect de serre - N°18: Bilan des gaz à effet de serre présents dans l’atmosphère, d’après les observations effectuées à l’échelle du globe en 2021
Cette édition du Bulletin contient la toute dernière analyse des observations recueillies dans le cadre du Programme de la Veille de l’atmosphère globale de l’OMM. Elle présente les fractions molaires en surface à l'échelle du globe du dioxyde de carbone (CO2), du méthane (CH4) et du protoxyde d'azote (N2O), et les compare avec les valeurs de l’année précédente et de l’époque préindustrielle. Elle donne également un aperçu de l’évolution du forçage radiatif induit par les gaz à effet de serre persistants ainsi que de la contribution de chaque gaz à cette augmentation.

WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.18: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2021
This Bulletin represents the latest analysis of observations from the WMO GAW Programme. It shows globally averaged surface mole fractions for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) and compares them with the mole fractions during the previous year and with the preindustrial levels. It also provides insights on the change in radiative forcing by long-lived GHGs (LLGHGs) and contribution of individual gases to this increase.
