GAW Report, 191. Instruments to Measure Solar Ultraviolet Radiation : part 4: Array Spectroradiometers
World Meteorological Organization (WMO) ; Bais A.; Bernhard G.; et al. - WMO, 2010 (WMO/TD-No. 1538)This paper is part four of a series of documents dedicated to instruments for the measurement of solar ultraviolet radiation. The series of documents has been drawn up by the WMO Scientific Advisory Group on UV Monitoring and the UV Instrumentation Subgroup. The aim of the series is to define instrument specifications and guidelines for instrument characterization that are needed for reliable UV measurements.
PWS, 21. Guidelines on early warning systems and application of nowcasting and warning operations
In 2010, a historic heat wave and numerous wildfires impacted Moscow and surrounding areas in the Russian Federation. At the same time, catastrophic flooding from unusually heavy monsoon rains was ongoing in Pakistan. Both events led to many fatalities and considerable human suffering. As climate change due to anthropogenic forcing continues, extreme weather events such as these are likely to become more common (IPCC 2007), further increasing the need for preparedness and early warning systems.
The need for robust early warning systems goes beyond purely natural disasters and extend ...
Guidelines for converting between various wind averaging periods in tropical cyclone conditions
World Meteorological Organization (WMO) ; Kepert Jeffrey David; Ginger J.D. - WMO, 2010 (WMO/TD-No. 1555)
GAW Report, 192. Guidelines for the Measurement of Atmospheric Carbon Monoxide
The Global Atmosphere Watch (GAW) Programme of the World Meteorological Organization (WMO) aims at providing reliable long-term observations of the chemical composition and physical properties of the atmosphere that are relevant for understanding atmospheric chemistry and climate change. Reactive gases are one of the foci of the GAW programme. This group includes carbon monoxide (CO), which is present only in trace quantities in the atmosphere but plays an important role in atmospheric chemistry. Compatibility of data from different observational platforms and sites is of crucial importance fo ...
WCDMP, 70. Guidelines for Plant Phenological Observations
The technical document on the guidelines for plant phenological observations raises the benefits of these types of observations in monitoring the impact of the changing climate on an important biosphere element of the climate system which is vegetation. The content of the document was elaborated by experts in climatology and biometeorology in a multidisciplinary team work approach. The guidelines included in the document are based on scientifically recognized principles and good practices undertaken by several institutions having long experience in carrying out plant phonological observations ...
GCOS, 128. Guideline for the Generation of Satellite-based Datasets and Products meeting GCOS Requirements
World Meteorological Organization (WMO) ; United Nations Environment Programme (UNEP); International Council for Science (ICSU); et al. - WMO, 2009 (WMO/TD-No. 1488)This document provides a short summary of GCOS requirements for satellite-based climate monitoring that can serve as a guideline for the generation of satellite-based datasets and derived products in order to meet the requirements for climate monitoring and the long-term aspects of climate research.
These guidelines are intended to help space agencies and other relevant institutions in the way they process and analyze datasets obtained from satellite instruments, to subsequently generate Essential Climate Variable (ECV) products (cf. Annex I and III).
Weather Forecasting for Soaring Flight
World Meteorological Organization (WMO) ; Organisation Scientifique et Technique Internationale du Vol à Voile (OSTIV) - WMO, 2009 (WMO-No. 1038)The aim of this handbook - prepared by Organisation Scientifique et Technique Internationale du Vol à Voile (OSTIV) - is to provide the reader an internationally agreed set of guidelines for meteorological forecasting in soaring flight and related activities.
WCDMP, 72. Guidelines on Analysis of extremes in a changing climate in support of informed decisions for adaptation
World Meteorological Organization (WMO) ; Zwiers Francis W.; Zhang Xuebin - WMO, 2009 (WMO/TD-No. 1500)
Flood Management Tool Series, Technical Document, 04. Organizing Community Participation for Flood Management
This tool provides general guidelines for effectively organizing community activities to ensure participation at various levels of decision-making and capacity building in flood management. Several issues related to the engagement of flood managers, NGOs, and policy makers in harmonizing community activities with other development policies and natural disaster, are also addressed to build necessary institutional frameworks to enhance community participation.
PWS, 18. Guidelines on Communicating Forecast Uncertainty
World Meteorological Organization (WMO) ; Martin Claire; Cacic Ivan; et al. - WMO, 2008 (WMO/TD-No. 1422)Communicating the uncertainty of the forecast is vital to users. It allows them to make better decisions that are attuned to the reliability of the forecast. It also helps to manage the expectations of users for accurate forecasts. These Guidelines address the issue of communicating forecast uncertainty. Although they include a discussion on the sources of uncertainty, and touch on the related science (e.g. probabilistic forecasting, the use of Numerical Weather Prediction (NWP) ensembles), this is not their focus. Rather, the emphasis is on how National Meteorological and Hydrological Servic ...
