Challenges in the Transition from Conventional to Automatic Meteorological Observing Networks for Long-term Climate Records
Guidelines for managing changes in climate observation programmes, with a set of recommended practices by which such changes can be managed, have already been published (WMO, 2007). This guidance note will focus on those AWSs likely to form part of long-term climate records. These will normally be owned by NMHSs or associated agencies, or sometimes by third parties (such as aviation, agriculture or road transport agencies) under standards endorsed by the NMHSs. Experience shows that private AWSs can be useful for some climate purposes (such as providing information on individual local-scale ex ...

Guidelines for managing changes in climate observation programmes, with a set of recommended practices by which such changes can be managed, have already been published (WMO, 2007). This guidance note will focus on those AWSs likely to form part of long-term climate records. These will normally be owned by NMHSs or associated agencies, or sometimes by third parties (such as aviation, agriculture or road transport agencies) under standards endorsed by the NMHSs. Experience shows that private AWSs can be useful for some climate purposes (such as providing information on individual local-scale extreme events) but rarely have the length of record, accuracy or exposure standards, or long-term stability of site and instrumentation, to have much value for monitoring on timescales of a decade or longer.

WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.13: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2016
The latest analysis of observations from the WMO GAW Programme shows that globally averaged surface mole fractions(2) calculated from this in situ network for CO2, methane (CH4) and nitrous oxide (N2O) reached new highs in 2016, with CO2 at 403.3 ± 0.1 ppm, CH4 at 1 853 ± 2 ppb(3) and N2O at 328.9 ± 0.1 ppb. These values constitute, respectively, 145%, 257% and 122% of pre-industrial (before 1750) levels. The record increase of 3.3 ppm in CO2 from 2015 to 2016 was larger than the previous record increase, observed from 2012 to 2013, and the average growth rate over the last decade. The El Niño ...

These values constitute, respectively, 145%, 257% and 122% of pre-industrial (before 1750) levels. The record increase of 3.3 ppm in CO2 from 2015 to 2016 was larger than the previous record increase, observed from 2012 to 2013, and the average growth rate over the last decade. The El Niño event in 2015/2016 contributed to the increased growth rate through complex two-way interactions between climate change and the carbon cycle. The increase of CH4 from 2015 to 2016 was slightly smaller than that observed from 2014 to 2015, but larger than the average over the last decade. The increase of N2O from 2015 to 2016 was also slightly smaller than that observed from 2014 to 2015 and the average growth rate over the past 10 years. The National Oceanic and Atmospheric Administration (NOAA) Annual Greenhouse Gas Index (AGGI) [3, 4] shows that from 1990 to 2016, radiative forcing by long-lived greenhouse gases (LLGHGs) increased by 40%, with CO2 accounting for about 80% of this increase.

Limitations of High-Resolution NWP Models
This scenario-based lesson examines how the limitations of high-resolution NWP forecasts affect their analyses and forecasts of winter and severe weather, and how best to use the output in light of the limitations. The lesson is structured around a case that occurred in Texas in December 2015 when winter weather and severe weather hit Amarillo and Dallas-Ft. Worth, respectively. As users go through the case, they learn how spin-up time, errors in initial conditions, and deficiencies in the modeling of mesoscale phenomena can impact high-resolution forecasts in the NAM nest and HRRR models.

Guidelines on Best Practices for Achieving User Readiness for New Meteorological Satellites
The current publication presents, in an integrated manner, best practices for user-readiness projects performed by user organizations (for example, NMHSs) as well as for satellite development programmes in support of user readiness. Definitions of and a timeline for deliverables are presented that should be made available by the satellite development programmes to user-readiness projects. The best practices documented here therefore apply to both user organizations (section 3) and satellite operators (section 5). The primary audiences for this publication are Members of the Coordination Group ...

Guidelines for the Assessment of Uncertainty for Hydrometric Measurement
In view of the increasing pressure on water resources, National Hydrological Services (NHSs) worldwide are faced with the challenge to deliver hydrological services of high quality, timeliness and proven credibility, to assist the decision making process of water and natural resources managers. Nowadays, it is commonly expected that these services must be based on information that includes an accurate assessment of its uncertainty. Stream discharge, the basic hydrological variable, is no exception, yet most measurements are still reported as a value without any information on its associated un ...

International Cloud Atlas: Manual on the Observation of Clouds and Other Meteors
This Atlas describes the classification system for clouds and meteorological phenomena used by all WMO Members. The classifications also describe meteorological meteors other than clouds – hydrometeors, lithometeors, photometeors, and electrometeors.
The Atlas provides a common language to communicate cloud observations, and ensures consistency in reporting by observers around the world. It serves as a training tool for meteorologists, as well as for those working in aeronautical and maritime environments, and it has become popular with weather enthusiasts and cloud spotters.
