GAW Report, 243. Report of the Fifth Erythemal UV Radiometers Intercomparison
This report presents the background information, procedures and results of the intercomparison of erythemal UV sensors carried out at the Central Observatory of Buenos Aires (OCBA) in 2018 against reference radiometers calibrated at the World Radiation Center (PMOD/WRC) in Davos during 2017. In this way, the data obtained at the measurement sites will be standardized and will be comparable locally and globally. Twenty sensors were calibrated, belonging to Argentine monitoring and research institutions. The associated relative uncertainty of each sensor was also estimated.

GAW Report, 242. 19th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases and Related Measurement Techniques (GGMT-2017)
The meeting reviewed current WMO data quality objectives, reference scales and observation strategies, including calibration, quality control, data management and archiving. Target species were carbon dioxide and other greenhouse gases, stable isotopes, and radiocarbon in greenhouse gas measurements. The workshop discussed in detail the harmonization and quality control of isotope measurements, the extension of the measurement network towards more polluted and urban areas, the use of low-cost sensors, and the collaboration of the scientific greenhouse gas and carbon cycle community with the me ...

Published by: WMO ; 2018The meeting reviewed current WMO data quality objectives, reference scales and observation strategies, including calibration, quality control, data management and archiving. Target species were carbon dioxide and other greenhouse gases, stable isotopes, and radiocarbon in greenhouse gas measurements. The workshop discussed in detail the harmonization and quality control of isotope measurements, the extension of the measurement network towards more polluted and urban areas, the use of low-cost sensors, and the collaboration of the scientific greenhouse gas and carbon cycle community with the metrology institutes. Many of the discussions were driven by recent technological developments in instrumentations. Analytical advancements have now made possible continuous high precision measurements of many previously difficult to measure compounds. In addition, we discussed the need to calculate and report uncertainties for all measurements.
The group updated the recommendations on WMO data quality objectives, calibration, and data management, as well as on the development of the GAW Programme in general. These recommendations are summarized in this meeting report.Collection(s) and Series: Technical publications GAW Report- No. 242

Published by: WMO ; 2018This concept note contains the expert recommendations resulting from discussions at the international workshop on Forecasting Emissions from Vegetation Fires and their Impacts on Human Health and Security in South-East Asia, which was hosted by the Indonesian Agency for Meteorology, Climatology and Geophysics (BMKG), Jakarta, from 29 August to 1 September 2016. The workshop was organized by the World Meteorological Organization (WMO) and the Interdisciplinary Biomass Burning Initiative (IBBI) in collaboration with the United Nations Office for Disaster Reduction/International Wildfire Preparedness Mechanism (UNISDR/IWPM), United Nations University (UNU), Global Wildland Fire Network (GWFN) through the Global Fire Monitoring Center (GFMC), Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, and the International Global Atmospheric Chemistry (IGAC) Project. Arising from the keen interest of WMO Members in several impacted regions, the note provides guidance for addressing the issues of vegetation fire and smoke pollution. It also proposes the establishment of a Vegetation Fire and Smoke Pollution Warning and Advisory System (VFSP-WAS) and to support the potential foundation of regional centers on the topic. Although most of the examples described here focus on the South-East Asian region, the concepts remain applicable to other regions (e.g. for Africa, Latin America, Northern Asia). “South-East Asia” as referred to in this note includes WMO Members from both Regional Associations II and V (Asia and South-West Pacific).

This Implementation Plan (IP) builds upon the growing importance of atmospheric composition observations and predictions, and focuses on research that enables a wide variety of Products and Services related to atmospheric composition. New GAW-lead thematic application areas will help reduce societal risks from climate change, high-impact weather and events, and urban air pollution, and support conventions and treaties focused on sustainable development. This IP is designed to help World Meteorological Organization (WMO) Members meet their needs and to support plans of national, regional, and i ...
