IOM Report, 99. WMO Field Intercomparison of Rainfall Intensity Gauges
The WMO Field Intercomparison of Rainfall Intensity Gauges was carried out in Vigna di Valle, Italy from October 2007 to April 2009, at the kind invitation of the Italian Meteorological Service. This intercomparison is following up on the Laboratory Intercomparison of Rainfall Intensity Gauges. CIMOXIV recommended that welldefined and accepted reference instruments and procedures were needed for the field intercomparison. CIMOXIV agreed that such reference might be based on a set of high quality devices applying different measuring techniques and had adopted a recommendation to that effect.

Published by: WMO ; 2009The WMO Field Intercomparison of Rainfall Intensity Gauges was carried out in Vigna di Valle, Italy from October 2007 to April 2009, at the kind invitation of the Italian Meteorological Service. This intercomparison is following up on the Laboratory Intercomparison of Rainfall Intensity Gauges. CIMOXIV recommended that welldefined and accepted reference instruments and procedures were needed for the field intercomparison. CIMOXIV agreed that such reference might be based on a set of high quality devices applying different measuring techniques and had adopted a recommendation to that effect. The main objective of this intercomparison was to intercompare the performance of in situ rainfall intensity instruments of different measuring principles in high rainfall intensity conditions. An International Organizing Committee was set up to determine and agree on the rules of the intercomparison and to support its preparation and execution. The IOC was also tasked to agree on the procedures used for the evaluation of the results and to review and agree on their presentation in the final report of the intercomparison. This report presents in a detailed manner the procedure that was adopted to determine the reference rainfall intensity, based on the measurements of 3 instruments placed in a pit. It also contains datasheets for each of the participating instruments, which provide exhaustive information on their performances throughout the intercomparison period in the field, as well as under laboratory conditions. The final conclusions of the report highlight the challenges that this type of measurements represents due to the high variability of rainfall intensity at a 1minute time scale. A number of recommendations were drawn from the results and address topics such as how to make best use of existing instruments, how to improve the design and documentation of the instruments as well as matters like the standardization of rainfall intensity measurements. Consequently, they are relevant to users, manufacturers and the meteorological community as a whole.

SP, 05. The potential role of WMO in Space Weather : a report on the potential scope, cost and benefit of a wmo activity in support of International coordination of space weather services, prepared for the sixtieth executive council
The present report addresses the possible scope, cost and benefit of initiating a WMO activity in the area of Space Weather. The expression Space Weather is used to designate processes occurring on the Sun, in the magnetosphere, ionosphere and thermosphere, which have the potential to affect the near-Earth environment. These processes occurring mainly outside of the atmosphere are not meteorological phenomena, and thus haven’t so far been considered within the mandate of WMO. However, because of their importance and possible synergy with activities under WMO’s responsibility, the issue o ...Permalink![]()

WCDMP, 70. Guidelines for Plant Phenological Observations
The technical document on the guidelines for plant phenological observations raises the benefits of these types of observations in monitoring the impact of the changing climate on an important biosphere element of the climate system which is vegetation. The content of the document was elaborated by experts in climatology and biometeorology in a multidisciplinary team work approach. The guidelines included in the document are based on scientifically recognized principles and good practices undertaken by several institutions having long experience in carrying out plant phonological observations ...Permalink![]()

IOM Report, 95. Global criteria for tracing the improvements of radiosondes over the last decades
This report represents the deliverable of the action initiated at the First Session of the Expert Team on UpperAir Systems Intercomparisons (ETUASI), Geneva, Switzerland, 2004: „To elaborate global criteria for tracing the improvements, based on previous intercomparisons and recent radiosondes development“. In the report, different approaches are identified with the objective to define these criteria, and the following method was selected as the most appropriate one: Time evolution of selected statistical parameters reported in the different IOM international radiosonde comparisons organized b ...Permalink![]()
