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).

GAW Report, 239. Calibration Methods of GC-μECD for Atmospheric SF6 Measurements
SF6 is a substance which originates only from anthropogenic sources used primarily in the electricity and electronics supply industries, e.g. the semiconductor industry, where it is used as an electronic insulator due to its inertness. SF6 is a trace gas that exists in small quantities at the level of ppt (parts-per-trillion, 1/1012) in the atmosphere, but its global warming potential is 23,500 times greater than that of CO2 when compared over a 100-year period[1]. In particular, SF6 has an atmospheric lifetime of 3,200 years upon emission, and will eventually exacerbate the man-made greenhous ...

Published by: WMO ; 2018SF6 is a substance which originates only from anthropogenic sources used primarily in the electricity and electronics supply industries, e.g. the semiconductor industry, where it is used as an electronic insulator due to its inertness. SF6 is a trace gas that exists in small quantities at the level of ppt (parts-per-trillion, 1/1012) in the atmosphere, but its global warming potential is 23,500 times greater than that of CO2 when compared over a 100-year period[1]. In particular, SF6 has an atmospheric lifetime of 3,200 years upon emission, and will eventually exacerbate the man-made greenhouse effect in the long term due to its higher radiative forcing, with greater significance in the future rather than in the present. Therefore, the measurement data of SF6 will carry significant importance as basic materials for future discussions on climate change. Since SF6 is a greenhouse gas that exists in trace quantities at 5-15 ppt in the atmosphere, measurement of the gas requires a very precise procedure. This document provides guidelines on how to produce more accurate and precise values in continuous atmospheric SF6 measurements, as well as the discrete sample analysis after collecting the air, preparation of standard gases for laboratory applications, and intercomparison experiments. These guidelines are also helpful to prepare the working standards, which have traceability to laboratory standards considering the scale propagation errors. In this guideline document, WMO scale (NOAA-X2014) is used for the calibrations. The instrument setup and analysis methods refer to WMO (2015)[2].

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 ...19th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases and Related Measurement Techniques (GGMT-2017)

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

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.Permalink![]()

World Meteorological Organization (WMO) ; United Nations Educational, Scientific and Cultural Organization (UNESCO); Intergovernmental Oceanographic Commission (IOC); et al. - WMO, 2018The Paris Agreement will drive climate policy for many years to come. It establishes a science-based cycle of reporting (through the Transparency Framework), assessment (the Global Stocktake) and increasing ambition of action to address climate change (Nationally Determined Contributions, NDC). The Agreement has three main aims: to limit the global temperature increase, to increase the adaptive capabilities of the Parties, and to increase the making finance flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development.
