WMO Solid Precipitation Intercomparison Experiment (SPICE) (2012 - 2015) : “Towards fit-for-purpose environmental measurements”
The Solid Precipitation Intercomparison Experiment (SPICE) was conducted as an internationally coordinated project, initiated and guided by the Commission for Instruments and Methods of Observation (CIMO) of the World Meteorological Organization (WMO). The SPICE field experiments took place between 2013 and 2015, with a preparatory stage during the winter of 2012/13.
SPICE was carried out as a major international effort, and has been remarkable for the diversity of organizations which hosted SPICE tests, contributed with instruments, and were engaged in the data analysis and the derivat ...EnglishWIGOS Technical Report, 2018-01. WIGOS, WMO Integrated Global Observing System - Benefits to the Environment and Society from the Availability and Use of AMDAR Data
This report presents an updated summary of AMDAR data usage and the resulting impacts and benefits to meteorological forecasting and the aviation industry. It then provides a presentation of the environmental and climate applications and studies that also benefit from the use of AMDAR data, as a result, bringing benefits to the environment and wider society. These areas of societal benefits include weather, transportation, energy, disaster reduction, health, climate and agriculture.EnglishIOM Report, 130. Fourth WMO Regional Pyrheliometer Comparison of RA II, Jointly held with RA V
This report describes the intercomparison in detail: the instruments, the participants, the experimental setup, method and procedure, the data analysis technique used and the results. It is clear from the results that all of the participating instruments have been well maintained and remained stable since the previous intercomparison, which augers well for all radiation measurements within RA II and RA V. All participants were able to return home with newly derived WRR reduction factors for their instruments.EnglishCommission for Instruments and Methods of Observations Open Programme Area Group on Remote-Sensing Technologies - Inter-Programme Expert Team on Operational Weather Radars
The key aims of this meeting were to consolidate important activities and plans for completing deliverables within the IPET’s work plan ahead of the upcoming session of CIMO in 2018. In particular, the IPET focused on reinvigorating activities and tasks towards the development of a Best Practices Guide on Operational Weather Radar. The team spent several sessions on developing the improved structure of the guide and drafting and organising materials under that structure. Additionally team members reported on the status and progress of other tasks in the work plan, including the successful comp ...EnglishCommission for Instruments and Methods of Observations OPAG in situ Technologies and Intercomparisons - Expert Team on Aircraft-based Observations : Final Report
The second session of the CIMO Expert Team on Aircraft-based Observations took place over 16-19 April, 2018 at the WMO headquarters in Geneva, Switzerland. This was the 2nd meeting of the team during the current inter-sessional period of CIMO ahead of the upcoming session of CIMO in October, 2018 (CIMO-17), with the first session having been held in December 2015 in conjunction with the CBS Expert Team on Aircraft-Based Observing Systems second session. The chief focus for the session was for the team to report on progress and to undertake planning to finalise activities and tasks from its wor ...EnglishIOM Report, 128. Interlaboratory Comparison in the field of Temperature, Humidity and Pressure, in the WMO Regional Association VI (MM-ILC-2015-THP)
The subject of this report is evaluation of the interlaboratory comparison in the field of measurement of temperature, humidity and pressure. The interlaboratory comparison was held within the framework of the MeteoMet 2 project, in the scope of proficiency testing scheme organized by the University of Ljubljana, Faculty of Electrical Engineering, Laboratory of Metrology and Quality (UL-FE/LMK), except pressure part. All the analysis were done in accordance with accredited procedures.EnglishMeteorological Instrument Performance Characteristics
NCAR's Earth Observing Laboratory ; The COMET Program ; Millersville University - The University Corporation for Atmospheric Research (UCAR), 2017This advanced lesson explores the performance characteristics of instrumentation used for meteorological measurements. Static performance characteristics are examined in the context of calibration, which offers a means to determine an instrument's response. Dynamic performance characteristics, including first and second order inputs, are discussed using three classic examples: step or impulse, ramp or time varying, and oscillatory inputs. The lesson provides information about the effects of representativeness and regional homogeneity on measurements, and also describes processes for obtaining ...Englishدليل استعمال الطيف الراديوي في الأرصاد الجوية: المراقبة والتنبؤ فيما يتعلق بالطقس والماء والمناخ
