PROBA-V Global Dataset 5 km - BHR

In the framework of the Spot/PROBA-V Surface Aerosol Retrieval at MEP (SPAR@MEP) ESA project, the CISAR algorithm, originally developed by Rayference for the joint retrieval of surface reflectance, aerosol and cloud single scattering properties, has been applied to PROBA-V observation globally during 2019 at 5km resolution. CISAR retrieves simultaneously the surface reflectance (represented by the RPV model) and the aerosol optical depth (AOD) in all PROBA-V bands plus the AOD at 500nm, with their corresponding pixel-level uncertainty. The retrieval uncertainty results from the propagation of all input, prior and inversion uncertainty through the inversion process. The processing has been performed in the Mission Exploitation Platform (MEP), developed by VITO. This Global Dataset includes the surface reflectance products. Specification on the filename convention, format and content of the products can be found on the Product Specification Document (PSD). The products related to the aerosol retrieval products.在欧洲空间局（European Space Agency, ESA）SPAR@MEP（Spot/PROBA-V地表气溶胶反演）项目的任务开发平台（Mission Exploitation Platform, MEP）框架下，由Rayference公司开发的、用于联合反演地表反射率、气溶胶与云单次散射特性的CISAR算法，已在2019年全球范围内应用于5km分辨率的PROBA-V卫星观测数据。CISAR算法可同时反演以RPV模型表征的地表反射率、所有PROBA-V波段的气溶胶光学厚度（Aerosol Optical Depth, AOD）以及500nm处的AOD，并输出对应像元级的不确定性结果。该反演不确定性源于所有输入数据、先验信息及反演过程中的不确定性在反演流程中的传递。本次数据处理工作由VITO公司开发的任务开发平台（Mission Exploitation Platform, MEP）完成。本全球数据集包含地表反射率产品，产品的文件名命名规则、格式与内容规范可查阅《产品规范文档》（Product Specification Document, PSD）。本次发布的产品与气溶胶反演产品相关联。
