At this site (a.k.a. 'Palgrunden'), the radiance emerging from the water has been measured since 2008 with a modified sun-photometer installed on the offshore lighthouse platform. The measured variable is labeled AERONET - Ocean Color (AERONET-OC).","citations":"Philipson P, Kratzer S, Ben Mustapha S, Str\u00f6mbeck N Stelzer K (2016) Satellite-based water quality monitoring in Lake V\u00e4nern, Sweden.

The network component called AERONET - Ocean Color (AERONET-OC) provides the additional capability of measuring the radiance emerging from the sea with sun-photometers installed on offshore platforms. \r\n\r\n\r\nIn 2007, within the context of ocean colour validation activities required for the Envisat mission, the European Space Agency (ESA) initiated a project for establishing and maintaining the AERONET-OC station on the P\u00e5lgrunden lighthouse in Lake V\u00e4nern with hand-on support from the Joint Research Centre in Italy (JRC). Instrument calibrations are performed at NASA Goddard Space Centre on yearly intervals. Currently, the station is funded by the Swedish National Space Board (SNSB).\r\n\r\n\r\nSite description: Platform: Lighthouse P\u00e5lgrunden ('Palgrunden'), close to Granvik (near Lidk\u00f6ping), Sweden, http:\/\/wlol.arlhs.com\/lighthouse\/SWE310.html. The instrument, a modified CIMEL CE-318 Sun photometer, is deployed at approximately 5 m above lake level and 49 m above sea level.
