It is based on longer observational records, new chemistry- climate model simulations, and new analyses.
WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.14: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2017
The latest analysis of observations from the WMO GAW Programme shows that globally averaged surface mole fractions(1) calculated from this in situ network for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2017, with CO2 at 405.5 ± 0.1 ppm(2), CH4 at 1859 ± 2 ppb(3) and N2O at 329.9 ± 0.1 ppb. These values constitute, respectively, 146%, 257% and 122% of pre-industrial (before 1750) levels. The increase in CO2 from 2016 to 2017 was smaller than that observed from 2015 to 2016 and practically equal to the average growth rate over the last decade. The influence ...

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.
ETR, 24. A Compendium of Topics to Support Management Development in National Meteorological and Hydrological Services
The present compendium of topics for management development is intended to help a NMHS establish management development programmes that meet the needs and culture of the organization. The provision of curricular (i.e. aims, learning outcomes and content), briefing notes, sources of further reading and discussion topics should make it easier to establish a bespoke programme rather than having to start from scratch. Even if an external agency provides the components of a management development programme, having the compendium should make it easier to specify what should be included. Regional Tra ...
IOM Report, 131. WMO Solid Precipitation Intercomparison Experiment (SPICE) (2012 - 2015)
The Solid Precipitation Intercomparison Experiment (SPICE) was conducted as an internationally coordinated project, initiated and guided by the Commission for Instruments and Methods of Observation (CIMO) of the World Meteorological Organization (WMO). The SPICE field experiments took place between 2013 and 2015, with a preparatory stage during the winter of 2012/13.
SPICE was carried out as a major international effort, and has been remarkable for the diversity of organizations which hosted SPICE tests, contributed with instruments, and were engaged in the data analysis and the derivat ...
Leveraging the Best Available Science for Increased Effectiveness of Climate Finance
Effective results from climate finance require evidence- and science-based information on the state and behavior of the Earth’s atmosphere, its interaction with the oceans, regional climates, and the resulting distribution of water resources. The high demand for such information, however, has led to a fragmented flow of internationally-funded projects that lack operational linkages with broader hydrological and meteorological systems and national-regional-global integration. To address this, the World Meteorological Organization (WMO) and the Green Climate Fund (GCF) have established an innova ...

Understanding the IPCC Special Report on 1.5°C
In 2015 governments adopted the Paris Agreement to tackle climate change (see below) and invited the IPCC to prepare a special report in 2018 to assess the impacts and related pathways of warming of 1.5ºC. This brief provides context and explanation of key concepts for policymakers, media and others about the Special Report on 1.5°C, scheduled to be published, subject to approval, by the Intergovernmental Panel on Climate Change (IPCC) on 8 October 2018. This brief is produced prior to the release of the report and therefore does not contain results from the report itself.
