IOM Report, 103. Evaluation Scheme for Regional Instrument Centres and Other Calibration Laboratories
The calibration of instruments and the traceability of meteorological measurements to the International Standard (SI) of units are crucial to ensure the quality of meteorological observations and to meet the users’ requirements. Regional Instrument Centres (RICs) play a key role in this context, by providing calibration services to other Members of their Region. In view of the need to ensure the quality of the services provided by the RICs, and the need for strengthening of RICs, the WMO Executive Council requested CIMO to develop a mechanism for their continuous evaluation to ensure quality o ...
IOM Report, 102. CIMO Survey on national summaries of methods and instruments for solid precipitation measurement at automatic weather stations
This publication reports on the results of the CIMO survey, initiated in 2008, on the current methods, instruments and challenges for the measurement of solid precipitation at automatic weather stations. The current survey is the third in its category. It was built on the two previous surveys that were conducted by CIMO 10 and 20 years ago. Since then, the automatic stations have been providing an increased percentage of precipitation data, snow water equivalent, and depth of snow on the ground. The CIMO, at its 14th session, initiated this review to assess the methods for measurement and obse ...

JCOMM Technical Report, 23. SIGRID-3 :a vector archive format for sea ice charts
Intergovernmental Oceanographic Commission (IOC); World Meteorological Organization (WMO) ; International Ice Charting Working Group's Ad Hoc Format Team for the WMO Global Digital Sea Ice Data Bank Project - WMO, 2010 (revised edition; WMO/TD-No. 1214)This document describes the SIGRID-3 format so that it may be understood by a variety of users and implemented by chart-producing ice centers or services. SIGRID-3 evolved from earlier SIGRID formats and incorporates much of their content (see Appendix 1 for notes on earlier SIGRID formats and their application in SIGRID-3). For example, SIGRID variable identifiers such as “CT” for total concentration are used in SIGRID-3. While all SIGRID variable identifiers may be used in SIGRID-3, those that are commonly used are required, such as concentration, stage of development, and form. Users famili ...

Abstracts - International Workshop on Addressing the Livelihood Crisis of Farmers: Weather and Climate Services
The International Workshop on Addressing the Livelihood Crisis of Farmers: Weather and Climate Services is taking place at a time when there is a growing concern about livelihoods of over 500 million smallholder farmers around the world coupled with the increasing climate variability and future climate change. The world population is projected to grow from 6.5 billion today to 8.3 billion in 2030 and nearly 9.2 billion in 2050. All of that growth will be concentrated in developing countries. Global food production will therefore need to increase by more than 50% by 2030, and should nearly doub ...
WWRP, 05. WWRP 2010-5 - 5th WMO Symposium on data assimilation
Improving the combination of observations and dynamical models by data assimilation systems has underpinned many advances in our understanding of the natural environment, and forecasting ability. These improvements, coupled with the development of ever more powerful computers and more sophisticated communication systems such as the internet and the World Wide Web have also heightened expectations. As a result, society is looking for further significant benefits from applications of meteorology, oceanography and hydrology.

PWS, 20. Administrative Procedure for Registering WMO Alerting Identifiers
In applications and services which support alerting, it is necessary to identify various information objects. This document enables the registration of Object IDentifiers (OIDs) for alerting information, i.e., content included in alert messages or otherwise associated with the activity of alerting. The Registration Authority, World Meteorological Organization (WMO), maintains these OIDs and accepts requests through WMO Members for the assignment of additional OIDs for information objects relevant to alerting. This document specifies rules for the registration of all such OIDs subordinate to th ...
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 ...
