Бюллетень ВМО по Парниковым Газам - № 17: Содержание парниковых газов в атмосфере по данным глобальных наблюдений в 2020 году
В настоящем бюллетене представлены результаты самого последнего анализа наблюдений, проведенных в рамках Программы ГСА ВМО. В нем приводятся глобально усредненные приземные мольные доли двуокиси углерода (CO2), метана (CH4) и закиси азота (N2O) и проведено их сравнение с мольными долями за предыдущий год и с доиндустриальными уровнями. Бюллетень также дает представление об изменении радиационного воздействия долгоживущих парниковых газов (ДПГ) и о вкладе отдельных газов в это увеличение.
WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.17: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2020
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.
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 ...
An Update on Low-cost Sensors for the Measurement of Atmospheric Composition, December 2020
Richard E. Peltier ; Núria Castell, Andrea L Clements, Tim Dye, Christoph Hüglin, Jesse H Kroll, Shih-Chun Candice Lung, Zhi Ning, Matthew Parsons, Michele Penza, Fabienne Reisen and Erika von Schneidemesser - WMO, 2021 (WMO-No. 1215)The report reflects on the state of the art in terms of accuracy, reliability and reproducibility of different sensors used for the measurements of reactive and greenhouse gases, and aerosols, along with the key analytical principles and what has been learned so far about low-cost sensors from both laboratory studies and real-world tests (up to August 2020). In some cases, scientific literature that had been accepted, but not yet published in a final form, was included in this review. Some national and international government documents were also included in this synthesis. The report includes ...
