OLCI Level 1B Full Resolution (version BC002) - Sentinel-3 - Reprocessed
收藏资源简介:
OLCI (Ocean and Land Colour Instrument) Full resolution: 300m at nadir. Level 1 products are calibrated Top Of Atmosphere radiance values at OLCI 21 spectral bands. Radiances are computed from the instrument digital counts by applying geo-referencing, radiometric processing (non-linearity correction, smear correction, dark offset correction, absolute gain calibration adjusted for gain evolution with time), and stray-light correction for straylight effects in OLCI camera's spectrometer and ground imager. Additionally, spatial resampling of OLCI pixels to the 'ideal' cross-track grid, initial pixel classification, and annotation at tie points with auxiliary meteorological data and acquisition geometry are provided. The radiance products are accompanied by error estimate products, however the error values are currently not available. Sentinel-3 is part of a series of Sentinel satellites, under the umbrella of the EU Copernicus programme. This collection contains reprocessed data from baseline collection 002. Operational data can be found in the corresponding collection.
海洋与陆地颜色仪器(Ocean and Land Colour Instrument, OLCI)全分辨率数据:星下点分辨率达300米。其一级产品为OLCI 21个光谱波段下的定标大气顶辐射亮度值。辐射亮度由仪器数字计数经以下流程计算得到:开展地理配准、辐射定标处理(包含非线性校正、拖影校正、暗偏移校正,以及针对随时间变化的增益演化进行校准调整的绝对增益定标),同时针对OLCI相机光谱仪与地面成像仪中的杂散光效应完成杂散光校正。此外,本数据集还提供OLCI像元至"理想"跨轨网格的空间重采样、初始像元分类,以及结合辅助气象数据与采集几何参数在连接点(tie points)上的标注信息。辐射亮度产品配套有误差估算产品,但当前误差值暂不可用。哨兵3号(Sentinel-3)隶属于欧盟哥白尼计划(Copernicus Programme)旗下的哨兵卫星系列。 本数据集包含基准数据集002(baseline collection 002)的再处理数据,对应的业务化数据可在相应数据集集中获取。
