Wind and wave dataset for Matara, Sri Lanka

Abstract

Abstract. We present the first continuous in situ hydro-meteorology observations from the south of Sri Lanka from a set of instruments deployed firstly in December 2012. The simultaneously record wind and wave data in this region are sparse due to difficulties in deployment. Here the survey, deployment and measurements of wind and wave are described with the aim of giving a future user of the data set as comprehensive information as possible. This study reviewed on-going access to the datasets of this survey project. The archived dataset was examined in detail, including wave data at two locations with water depths of 20 m and 10 m comprising synchronous time-series of wind, ocean astronomical tide, air pressure and so on. In addition, we use these wave observations to evaluate the ERA-Interim reanalysis product and demonstrate that it represented near-shore waves in this region not very well. The buoy 2 observations showed that the swell is the main parts in all year and the monsoon can markedly adjusted the proportion between swell and wind seaa. The data set made publicly available from Science Data Bank (http://www.sciencedb.cn/dataSet/handle/447).
