Guide to the WMO Integrated Global Observing System
This edition of the Guide provides material relevant to some of the new WIGOS-related regulations. The topics cover the new system of WIGOS station identifiers, the new requirements to record and make available metadata as specified in the WIGOS Metadata Standard, the new Observing Systems Capability Analysis and Review (OSCAR) tool to be used by Members to submit metadata for WMO global compilation, the new observing network design principles, national WIGOS implementation, WIGOS data partnerships, Regional WIGOS Centres, and WIGOS Data Quality Monitoring System for surface-based observations ...
Commission for Basic Systems and Commission for Instruments and Methods of Observation : Workshop on Use of Unmanned Aerial Vehicles (UAV) for Operational Meteorology
The workshop presentations included research organizations and NMHS experts discussing the challenges and successes experienced using UAVs in field campaigns collecting data in support of environmental and meteorological applications. The challenges included airspace use regulations and technical capabilities of the UAVs. UAV industry representatives spoke to the workshop audience on the types and capabilities of UAVs and about their collaboration in field campaigns with research organizations and NMHS represented at the workshop. IATA and other experts informed the workshop audience of the va ...
Guide to Instruments and Methods of Observation
The first edition of this guide was published in 1950.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 ...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.
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.

Organisation météorologique mondiale (OMM) - OMM, 2015 (édition 2015 mise à jour en 2018; OMM-No. 306)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.
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).
