TurboWin version 5.0 for Windows (November 2011)
TurboWin was developed at KNMI (Royal Netherlands Meteorological Institute) with contributions from several National Meteorological Services and endorsed by the WMO (World Meteorological Organization) and E-SURFMAR (European Surface Marine Programme). Meteorological observations made on board ships and fixed sea stations are a substantial component of the World Weather Watch provided that the observation are accurate and of high quality. The fixed sea stations and VOS (Voluntary Observing Ships) are key components of the GOS (Global Observing System) and climate research. At the same time, however, it has been recognised that these observations are subject to keying errors, coding errors, calculating errors, etc.. To achieve an optimal control of the quality of the observations, before they are used in real time, the quality control has to be carried out at the root, by the observers themselves. TurboWin contains observation checking routines which are applied on the observations before they are transmitted. TurboWin is a user-friendly system with over 200 built-in quality checks. It allows the automated compilation of observations on board ships and fixed sea stations, their downloading to disk and their subsequent transmission ashore and thence to a Meteorological Centre, by using Inmarsat, E-mail or other specific communication facilities. The program assists the observer with many menus, pictures, photos, forms, help pages, output options, automated calculations etc..

Ocean Wave Atlas version 2.0 for Windows and Linux (April 2004)
Climate charts with wave height, direction and period. Climate is by definition the synthesis of weather conditions in a given area, characterized by long-term statistics (mean values, standard deviations, etc.) of the meteorological elements in that area. According to the World Meteorological Organization (WMO) it should preferably be based on 30 years of data. To conform with this recommendation the mean wave climate information we provide was based on 30 years of ERA-40 data from 1971 to 2000. The data is of high quality, especially in terms of monthly means and other longer-term statistics, when compared with competing datasets.

MetPub47 version 1.1 for Windows (March 2007)
This program helps with collecting metadata for WMO Publication No. 47. WMO Publication No. 47 (Pub47), the International List of Selected, Supplementary and Auxiliary Ships, contains details about the names, call signs, ship layout, types of instrumentation and methods of observation used on VOS ships. It relies on the regular submission of metadata from National Meteorological Services operating VOS programmes, nominally on a quarterly basis.

Accurate details about the method of observation and instrument type, instrument exposure, instrument calibration dates and ship layout, are vital if the objectives and desired accuracies of (VOS) climate monitoring programs are to be achieved.
