AIMS Remote Sensing Data (Great Barrier Reef Subset)

This dataset consists of products generated from satellite remote sensing data received at AIMS or obtained from other sources.Currently there are three products: (Skin) Sea Surface Temperature (SST); Chlorophyll-a (Chl a); and Diffuse attenuation coefficient at 490nm (K490). The SST data are derived from data from the AVHRR sensor on the NOAA series satellites received at AIMS and currently covers the period from June 2003 to present. This dataset will be expanded back to 1990 in the near future. The Chl a and K490 ( an ocean turbidity proxy) are derived from data from the SeaWiFS sensor on board the Orbview-2 satellite. These products are available for the period January 1998 to August 2005.The datasets will also be augmented with data from the MODIS sensor on the EOS satellites. This data will be sourced from NASA for the period prior to installation of the AIMS X-band ground-station and then from directly received data. To provide ready access to satellite remote sensing products covering the GBR subset region. The dataset contains products generated from SeWiFS data covered by a "Research use only" agreement with GeoEYE and may only be used for research or educational purposes.

本数据集旨在为用户便捷获取覆盖大堡礁（GBR）子区域的卫星遥感产品提供支撑，其包含由澳大利亚海洋科学研究所（AIMS）接收的卫星遥感数据，或从其他渠道获取的数据所生成的各类产品。目前本数据集涵盖三类产品：（表皮）海表温度（Sea Surface Temperature, SST）、叶绿素a（Chlorophyll-a, Chl a）以及490纳米处的漫衰减系数（Diffuse Attenuation Coefficient at 490nm, K490）。海表温度数据源自AIMS接收的NOAA系列卫星上搭载的先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer, AVHRR）的观测数据，当前覆盖时段为2003年6月至今，且将于近期回溯扩充至1990年。叶绿素a与490纳米漫衰减系数（后者为海洋浊度替代指标）的数据源自Orbview-2卫星搭载的SeaWiFS传感器观测数据，上述两类产品的覆盖时段为1998年1月至2005年8月。本数据集还将补充EOS系列卫星上搭载的中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）的观测数据：在AIMS X波段地面站建成之前，该类数据将从美国国家航空航天局（NASA）获取；地面站建成后，则直接由AIMS接收。需注意，本数据集包含由SeaWiFS数据生成的产品，该类数据受与GeoEYE签署的"仅可用于科研用途"协议约束，仅可用于科研或教育目的。
