MERIS - Water Parameters - Baltic Sea, 10-Day

The Medium Resolution Imaging Spectrometer (MERIS) on Board ESA’s ENVISAT provides spectral high resolution image data in the visible-near infrared spectral region (412-900 nm) at a spatial resolution of 300 m. For more details on ENVISAT and MERIS see http://envisat.esa.int/
Spectral high resolution measurements allow to assess different water constituents in optically complex case-2 waters (IOCCG, 2000). The main groups of constituents are Chlorophyll, corresponding to living phytoplankton, suspended minerals or sediments and dissolved organic matter. They are characterised by their specific inherent optical properties, in particular scattering and absorption spectra.
The Baltic Sea Water Constituents product was developed in a co-operative effort of DLR (Remote Sensing Technology Institute IMF, German Remote Sensing Data Centre DFD), Brockmann Consult (BC) and Baltic Sea Research Institute (IOW) in the frame of the MAPP project (MERIS Application and Regional Products Projects). The data are processed on a regular (daily) basis using ESA standard Level-1 and -2 data as input and producing regional specific value added Level-3 products. The regular data reception is realised at DFD ground station in Neustrelitz.

欧洲空间局（European Space Agency，ESA）搭载于ENVISAT卫星的中分辨率成像光谱仪（Medium Resolution Imaging Spectrometer，MERIS）可获取可见光-近红外光谱区间（412~900 nm）内的高光谱影像数据，空间分辨率为300米。有关ENVISAT与MERIS的详细信息可访问http://envisat.esa.int/。

高光谱测量技术可用于评估光学复杂二类水体（International Ocean Colour Coordinating Group，IOCCG，2000）中的多种水体质成分。主要成分类别包括对应活体浮游植物的叶绿素、悬浮矿物与沉积物以及溶解性有机物，这些成分以其特定的固有光学特性为核心特征，尤以散射光谱与吸收光谱为典型代表。

波罗的海水体成分数据集由德国航空航天中心（Deutsches Zentrum für Luft- und Raumfahrt，DLR，其下设遥感技术研究所IMF与德国遥感数据中心DFD）、布罗克曼咨询公司（Brockmann Consult，BC）以及波罗的海研究所（IOW）在MAPP项目（MERIS应用与区域产品项目）框架下合作开发。该数据集以ESA标准一级与二级数据为输入，按日定期处理并生成具备区域特色的增值型三级产品。常规数据接收工作由位于新施特雷利茨的DFD地面站完成。
