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 ...
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.
Meteorological Instrument Performance Characteristics
NCAR's Earth Observing Laboratory ; The COMET Program ; Millersville University - The University Corporation for Atmospheric Research, 2017This advanced lesson explores the performance characteristics of instrumentation used for meteorological measurements. Static performance characteristics are examined in the context of calibration, which offers a means to determine an instrument's response. Dynamic performance characteristics, including first and second order inputs, are discussed using three classic examples: step or impulse, ramp or time varying, and oscillatory inputs. The lesson provides information about the effects of representativeness and regional homogeneity on measurements, and also describes processes for obtaining ...
WIGOS Technical Report, 2016-01. AMDAR Benefits to the Air Transport Industry
This report describes and documents the benefits that the Air Transport Industry (ATI) gains from increased forecast accuracy achieved through the daily collection of atmospheric data gathered by approximately 4,000 inflight commercial aircraft. The report also outlines the Aircraft Meteorological DAta Relay (AMDAR) observing system, the forecast process and describes the importance that AMDAR data plays in numerical weather prediction (NWP).
Measuring the benefits to the ATI requires first to describe and to quantify the improved weather forecast accuracies due solely to the assimilat ...
WIGOS Technical Report, 2015-01. Impact and benefits of AMDAR temperature, wind and moisture observations in operational weather forecasting
This report reviews the impact of AMDAR observations on operational NWP forecasts at both regional and global scales that support national and local weather forecast offices across the globe.
The WMO AMDAR Observing System : Benefits to airlines and aviation
A 4-page brochure, developed and published by WMO, that briefly explains the benefits of the AMDAR observing system to airlines and the aviation industry.
Всемирная метеорологическая организация Технический отчет, 2014-02. Требования к осуществлению и функционированию программы AMDAR
В настоящем документе представлено руководство для стран-членов ВМО относитель-но требований к созданию и эксплуатации в сотрудничестве с одной или несколькими партнерскими коммерческими авиакомпаниями национальной или региональной систе-мы наблюдений AMDAR. Данный документ был составлен и пересмотрен экспертами в области систем наблюдений стран-членов ВМО, включая членов группы экспертов по системам наблюдений с бортов ВС (ET-ABO) Комиссии по основным системам (КОС) ВМО.
WIGOS Technical Report, 2014-02. Requirements for the Implementation and Operation of an AMDAR Programme
This document provides guidance to WMO Members on the requirements for the establishment and operation of a national or regional AMDAR observing system in collaboration with one or more partner commercial airlines. It has been contributed to and reviewed by observing system experts of WMO Members, including members of the WMO Commission for Basic Systems (CBS) Expert Team on Aircraft-Based Observing Systems (ET-ABO).
Introduction to Aircraft Meteorological Data Relay (AMDAR)
Introduction to Aircraft Meteorological Data Relay (AMDAR) provides national meteorological services worldwide, airlines, and aviation organizations with information about the World Meteorological Organization (WMO) aircraft-based observing system. The audience includes meteorological service managers and providers, observational development groups, the aviation industry, and others interested in benefiting from an aircraft-based observing system in their region. The content includes interviews with several experts to provide examples of AMDAR use for both meteorological and aviation applications. Additional details about the systems and requirements for implementing AMDAR are also included.
Guide to the Global Observing System
The main purpose of this guide is to provide practical information on the development, organization, implementation and operation of the Global Observing System in order to enhance both the participation of individual Members in the System and the benefits they may obtain from it. The Guide explains and describes Global Observing System practices, procedures and specifications and is aimed at assisting the technical and administrative staff of National Meteorological Services responsible for the networks of observing stations in preparing national instructions for observers.
