JCOMM Technical Report, 57. Extreme value analysis: wave data
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2011In this report we begin by describing and discussing approaches that can be used to estimate such return values in Chapter 2. Approaches based on extreme value theory as well as ad hoc methods are considered. We then present in Chapter 3 some worked examples using two time series of significant wave height measurements, one in deep and the other in shallow waters. In Chapter 4 we provide an inventory of software packages available to carry out extreme value analyses. We finish in Chapter 5 with some guidelines / recommendations.
JCOMM Technical Report, 58. Extreme value analysis: still water level
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2011In this report we begin by describing and discussing approaches based on extreme value theory that can be used to estimate return values of SWL in Chapter 2. We then present in Chapter 3 a worked example using a long-term time series of still water level measurements processed and quality-checked by the Dutch Ministry of Transport, Public Works and Water Management. They are the measurements of the gauge located at Hoek van Holland, The Netherlands (see Figure 3.1), available from 1887 onwards. In Chapter 4 we provide an inventory of software packages available to carry out extreme value analy ...
JCOMM Technical Report, 56. JCOMM Expert Team on Sea Ice (ETSI): 3rd Ice Analysts’ Workshop
Ice (ETSI), Dr. Vasily Smolyanitsky (Russian Federation), at 0900 hrs on Tuesday 18 June 2011 at the Danish Meteorological Institute, Copenhagen, Denmark. Dr. Smolyanitsky noted that the Ice Analysts’ Workshops are endorsed by both JCOMM and the International Ice Charting Working Group (IICWG) as being a valuable forum to share knowledge and coordinate ice information services throughout the world. Recognizing the increasing navigation that is taking place in the Arctic, five new METAREAs were created 3 years ago to ensure that Marine Safety Information (MSI) through the Global Global Maritime ...
JCOMM Technical Report, 59. Proceedings of the third International workshop on advances in the use of historical marine climate data
Marine surface observations—which represent a vital component of the Global Climate Observing System (GCOS)—are key to understanding global climate, including its variability on time scales ranging from sub-daily to weekly to centuries. Prior to 1970, ships were almost the only source of observations. In the modern era, sensors deployed on ships, moored and drifting buoys, aircraft, and Earth Observation (EO) satellites all provide surface measurements of many different variables. The Third International Workshop on Advances in the Use of Historical Marine Climate Data (MARCDAT-III) was hosted ...

World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2011
JCOMM Meeting Report, 84. Ship Observations Team - Sixth session : final report
The Sixth Session of the JCOMM Ship Observations Team (SOT) was held at the auditorium of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Division of Marine and Atmospheric Research (CMAR), Hobart, Australia, from 11 to 15 April 2011 at the kind invitation of the Government of Australia. The Session was co-sponsored by the Australian Bureau of Meteorology (BOM) and CSIRO.
As for previous SOT Sessions, a technical and scientific workshop focusing on new initiatives and / or new developments in shipboard meteorological or oceanographic instrumentation, observing ...

JCOMM Meeting Report, 85. JCOMM Observations coordination group: fourth session : final report
The Fourth Session of the JCOMM Observations Coordination Group (OCG) was held in Hobart, Australia, from 18 to 20 April 2011, at the kind invitation of the Government of Australia. The Session was sponsored by the Australian Bureau of Meteorology (BOM). The meeting focused on issues and actions that would help improve the 'systems' aspects of JCOMM, and on collaboration that would appeal and help each individual component. The Group reviewed requirements, refined the implementation goals for the observing networks, and addressed common technical coordination through JCOMMOPS. It noted the nee ...

JCOMM Meeting Report, 86. Data buoy co-operation panel: twenty-seventh session : final report
The twenty-seventh session of the Data Buoy Co-operation Panel (DBCP-27) was held in Geneva, Switzerland, from 26 to 30 September 2011, at the headquarters of the World Meteorological Organization (WMO).
A technical and scientific workshop was organized during the first day of the session. 17 presentations were delivered under the themes of operational practices and enhancements, technical development for marine observation systems, applications of collected data, and requirements for climate applications. Approximately 70 participants from 17 countries attended the meetings.
JCOMM Technical Report, 55. WCRP-JCOMM Workshop on Coordinated Global Wave Climate Projections (COWCLIP)
World Meteorological Organization (WMO) ; Wang Xiaolan L.; Weisse Ralf; et al. - WMO, 2011 (WMO/TD-No. 1518)The Coordinated Ocean Wave Climate Projections (COWCLIP) workshop was held on April 11-13, 2011, at the World Meteorological Organization (WMO) in Geneva, Switzerland, with the support of the World Climate Research Programme and the Joint Technical Commission for Oceanography and Marine Meteorology of WMO and Intergovernmental Oceanographic Commission (IOC) of UNESCO. The workshop aimed to bring together international researchers with interest in wind wave climate variability and change, to discuss the potential path forward for a collaborative working group to address challenges in this field ...
JCOMM Meeting Report, 87. JCOMM Marine Instrumentation Workshop for the Asia Pacific Region - final report
The JCOMM Marine Instrumentation Workshop for the Asia Pacific Region was held in Tianjin, China, from 11 to 13 July 2011 at the kind invitation of the State Oceanic Administration (SOA) and the National Centre of Ocean Standards and Metrology (NCOSM) of China.
The workshop recalled the importance of ocean observations to achieve socio-economical benefits at the global, regional, national, and local (e.g. Tianjin city) levels by addressing the requirements of WMO and IOC Applications, including the Global Framework for Climate Services (GFCS), and working in the multi-disciplinary fram ...
Joint WMO/ IOC for Oceanographic and Marine Meteorology (JCOMM), 48. Project Report - Pilot Project for the Integration of marine meteorological and other appropriate oceanographic observations into the WMO Integrated Global Observing System (WIGOS) : (WIGOS Pilot Project V - JCOMM Pilot Project for WIGOS)
This Project report provides rationale for the development of the Pilot Project, summarizes the activities undertaken under the Pilot Project, especially with regard to its three key deliverables, and provides information on its achievements, and lessons learned. In the context of marine meteorological and oceanographic observations relevant to WMO Programmes and Co-sponsored Programmes, this report explains the benefits of WIGOS integration for National Meteorological and Hydrographic Services (NMHSs), National Oceanographic Data Centres (NODCs, of IOC), and also for ocean data users. It prov ...
