WMO Guidelines on Generating a Defined Set of National Climate Monitoring Products (WMO-No. 1204)
The aim of this publication is to provide a specification for the shortlist of NCMPs that can be produced consistently and easily by most countries. By having clearly defined NCMPs, it should be possible for countries with fewer resources to focus their efforts on a small number of products that have wide applicability and interest.
التحديات في الانتقال من الشبكات التقليدية إلى الشبكات الأوتوماتية لرصد الأحوال الجوية من أجل السجلات المناخية طويلة الأجل
نُشرت بالفعل (WMO, 2007) توجيهات لإدارة التغيرات في برامج رصد المناخ، مع مجموعة ممارسات موصى بها يمكن بواسطتها إدارة هذه التغيرات. وسينصب التركيز في هذه المذكرة التوجيهية على محطات الأرصاد الجوية الأوتوماتية (AWSs) التي يرجح أن تشكل جزءاً من السجلات المناخية طويلة الأمد. وستكون هذه السجلات عادة مملوكة للمرافق الوطنية للأرصاد الجوية والهيدرولوجيا (NMHSs) أو للوكالات المنتسبة لها، أو لأطراف أخرى أحياناً (من قبيل هيئات الطيران أو الزراعة أو النقل البري) في إطار المعايير التي تقرها المرافق الوطنية (NMHSs). وتثبت التجربة أن المحطات (AWSs) الخاصة يمكن أن تكون مفيدة لبعض الأغراض المناخية (مثل توفير م ...
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 ...
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 ...
WCDMP, 85. Ninth Seminar for Homogenization and Quality Control in Climatological Databases and Fourth Conference on Spatial Interpolation Techniques in Climatology and Meteorology
In this paper we try to summarize the main topics of homogenization, quality control and spatial interpolation.
GAW Report, 228. WMO Global Atmosphere Watch (GAW) Implementation Plan: 2016-2023
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 ...
Guide to the Direct Broadcast Network for Near-real-time Relay of Low Earth Orbit Satellite Data
The purpose of this Guide is to define the minimum technical specifications and procedures applicable to the Direct Broadcast Network for Near-real-time Relay of Low Earth Orbit Satellite Data (DBNet) and to provide guidance for implementing these specifications and procedures.
In the present Guide, the term “shall” is used when referring to the technical specifications and procedures that have to be applied for DBNet to work properly, and the term “should” when referring to those that would enhance the proper functioning of DBNet. The DBNet technical specifications are applica ...

Guide to the Implementation of Quality Management Systems for National Meteorological and Hydrological Services and Other Relevant Service Providers
The objective of this publication is to provide guidance to WMO Members on how to develop and implement a quality management system (QMS). The Guide details the steps required to obtain certification of compliance with the ISO standard ISO 9001:2015, Quality Management System – Requirements (ISO, 2015c)It also provides the steps for transition from ISO standard ISO 9001:2008 (ISO, 2008) to standard ISO 9001:2015 (ISO, 2015c). It is especially focused on WMO Member National Meteorological and Hydrological Services (NMHSs). However, it could be successfully utilized by other service providers, ...
Guidelines on the Role, Operation and Management of National Meteorological and Hydrological Services
These Guidelines are intended to provide a one-stop, consistent and contemporary reference resource from the World Meteorological Organization (WMO) for managers of National Meteorological and Hydrological Services (NMHSs). They should help with many of the challenges that directors and managers of NMHSs face, including:
– Ensuring that the NMHS is able to meet national needs for meteorological, hydrological and related data and services;
– Responding to newly identified challenges in a rapidly changing world;
– Clarifying and articulating the mandate of the NMHS;
– ...
IOM Report, 126. Quality Assessment using METEO-Cert : The MeteoSwiss Classification Procedure for Automatic Weather Stations
It this report, METEO-Cert and its application is described. The METEO-Cert process assigns qualitative flags to each station and its instruments. Those qualitative flags provide valuable information on the applicability of the measured data and help to identify potential improvement of the station’s exposure.
