This collection of datasets contains data measured by two weather stations related to the OBSEA platform since Feb, 2010. The first weather station is deployed at the OBSEA buoy, the second is located at the OBSEA shore station on top of the UPC building. OBSEA is a permanent underwater cabled seabed observatory located in front of the Catalan's coast near Barcelona, at 20 m depth which is used as a test site for different experiments related with marine sensors. It has a sea station and a ground station, which include a surface buoy equipped with weather station and camera and a coastal cabled system (seabed platform). OBSEA is part of the European Multidisciplinary Seafloor Observatory (EMSO) infrastructure and participates as a Coastal Observatory data provider and Test Site on the JERICO-RI. For a comfortable handling of these weather station data they were summarized monthly to one data set each. A complete list of the datasets belonging to this collection can be found at the end of this page.
