IOM Report, 121. Measurement of upper-air pressure, temperature and humidity
This report is that document, as authored by Dr Nash, in all its original detail. Starting with the existing version of the CIMO Guide (2010 update) Dr Nash revised that information, primarily to include the additional understanding gained from the Yangjiang intercomparison. At the same time, though, he added a wealth of further specialist knowledge, gained from his protracted involvement in WMO CIMO activities over more than thirty years, and in particular from his participation in all eight CIMO international radiosonde intercomparisons, commencing with the first, held at Bracknell in 1983.< ...
WCDMP, 84. Eighth Seminar for Homogenization and Quality Control in Climatological Databases and Third Conference on Spatial Interpolation Techniques in Climatology and Meteorology
The 8th Homogenization Seminar and the 3rd Conference on Spatial Interpolation were organized together considering certain theoretical and practical respects. Theoretically there is a strong connection between these topics since the homogenization and quality control procedures need spatial statistics and interpolation techniques for spatial comparison of data. On the other hand the spatial interpolation procedures (e.g. gridding) need homogeneous data series with high quality. Practically the CARPATCLIM project that was launched in 2010 and ended in 2013 is a good example for this problem. Th ...

SDS-WAS, 2015-001. Dust/ sand storms over Libya : Spatial distribution, frequency and seasonality, technical report
The climate of most of the coastal region of Libya can be classified as semi-arid, while that of the rest of the country is arid. Rainfall is erratic with extremely variable yearly rainfall amounts: a series of dry years may follow a year with adequate rainfall. Furthermore, monthly and seasonal totals are not homogenous and most precipitation occurs during winter months.
Dust and sand storms, the focus of the present study, are one of the main extreme weather phenomena that affect Libya. In this paper, spatial and temporal distribution, frequency and seasonality are studied and analyze ...
Flood Management Tool Series, Technical Document, 23. Health and Sanitation Aspects of Flood Management
Flood events are known for their profound capacity to positively or negatively affect humans. Floods improve overall human well-being by providing services such as groundwater recharge, surface-water replenishment, soil-fertility enhancement and a general increase in the value of social–ecological systems. Equally, however, flood events pose a series of diverse health threats, ranging from contaminated water sources to decreased agricultural productivity, especially when communities are vulnerable and lack the capacity to effectively respond to, and recover from, the adverse effects of floods. ...
Flood Management Tool Series, Technical Document, 22. The role of the media in flood management
Communication is the imparting or exchange of information between individuals or groups through a common system of symbols, signs or behaviour (Merriam-Webster, 2013a; Oxford Dictionaries, 2013). In recent decades, different conceptual models have been developed to explain the process of human communication. One of the best representations of the flow of information in flood communication is the Interactional Communication Model proposed by Schramm (Schramm, 1954).
Flood Management Tool Series, Technical Document, 21. Effectiveness of flood management measures
It is not enough to assert—to an elected official, a regulator, a donor organization or the taxpayer—that one’s organization is doing an effective job of flood management. One also has to be able to provide a credible answer to the question: “How do you know?” 2 There is a multiplicity of flood management activities that can be pursued by a plethora of government jurisdictions, government agencies, NGOs, private and volunteer groups— independently, in cooperation, in competition. These activities may include: constructing flood prevention infrastructure; rebuilding houses, buildings and infras ...
