AGM, 11. Agricultural drought indices : proceedings of an expert meeting
World Meteorological Organization (WMO) ; Motha Raymond P.; Wilhite Donald A.; et al. - WMO, 2011 (WMO/TD-No. 1572)The Murcia Expert Meeting is based on the outcomes of the Regional Workshop on Indices and Early Warning Systems for Drought which was held at the University of Nebraska-Lincoln in December, 2009. At the Lincoln workshop, drought experts examined what indices are used for meteorological, agricultural and hydrological drought and developed the Lincoln Declaration on Drought Indices. There was a consensus agreement that the Standardized Precipitation Index (SPI) should be used to characterize meteorological droughts by all NMHSs around the world. Several other of the recommendations formt eh Lin ...
GAW Report, 194. 15th WMO/IAEA Meeting of Experts on Carbon Dioxyide, other Greenhouse Gases and Related Tracers Measurement Techniques
The 15th WMO/IAEA Meeting of Experts on Carbon Dioxide, Other Greenhouse Gases and Related Tracers Measurement Techniques took place from 7 to 10 September 2009 at the MaxPlanck-Institute for Biogeochemistry in Jena, Germany. The meeting reviewed current WMO data quality objectives, covering such topics as carbon dioxide and other greenhouse gases, stable isotopes, radiocarbon in greenhouse gas measurements, calibration, quality control, data management and archiving. The experts also discussed new and emerging technologies, including measurements of greenhouse gases with high-precision spectr ...

CIMO IOM Reports No.95 to 103
World Meteorological Organization (WMO) - WMO, 2010 (WMO/TD-No. 1433, 1494, 1501, 1504, 1542, 1543, 1544, 1545)
IOM Report, 101. Guidance on Instrumentation for Calibration Laboratories, including Regional Instrument Centres
Users of meteorological observations have increasing needs for high quality meteorological and hydrological data. The traceability of these data to the International System of Units (SI) standards is needed to ensure their quality and to meet the users’ requirements. Regional Instrument Centres, as well as NMHSs calibration laboratories are essential in ensuring data quality by providing calibration of the standards and traceability to SI. CIMOXIV recognized that RICs needed guidance on how to build calibration laboratories and purchase calibration equipment to strengthen their capabilities. T ...

JCOMM Technical Report, 52. Eleventh International Workshop on Wave Hindcasting and Forecasting and Second Coastal Hazard Symposium
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2010 (WMO/TD-No. 1533)
JCOMM Technical Report, 51. Ship Observations Team (SOT) annual report for 2009
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2010 (WMO/TD-No. 1525)
JCOMM Technical Report, 04. The Voluntary Observing Ships Scheme, a Framework Document
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2010Ships of the World Meteorological Organization (WMO) Voluntary Observing Ship (VOS) scheme have always been an important component of the global observing system of the WMO, providing meteorological and oceanographic data essential to operational meteorology, maritime safety services, and a range of marine climatological applications. More recently, it has become clear that their observations can also be of critical importance to global climate studies.
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 ...
IOM Report, 100. Evaluation of the Survey on Lightning Detection Systems - Report on Current Operational Networks
This publication reports on the results of the CIMO survey on lightning detection systems. This survey was the first in its category. It was initiated by the CIMO in its 14th intersession period as part of a review of the current operational lightning detection systems networks used by Members, to assess the need and possibility to organize an intercomparison of such systems. In that context, CIMO charged the Expert Team on Remote Sensing UpperAir Technology and Techniques to conduct this work. This IOM Report, prepared by a member of the Expert Team, Mr Mohamed Dahoui provides the results of ...
