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.

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.

This document specifies rules for the registration of all such OIDs subordinate to th ...
Global sea-level rise update
Sea level is higher now and is rising much more rapidly than at any other time in the past 3 000 years. We know that sea level will continue to rise for many centuries, even after global temperatures are stabilized, as it takes that long for the ocean and ice sheets to respond fully to a warmer climate. Unchecked global warming is likely to raise sea level by several metres in coming centuries, leading to the loss of many coastal cities and entire island states. This longer-term threat is already being exacerbated by increased frequency of short-term extreme sea levels due to the superposition ...
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 ...
