CALIPSO Wide Field Camera Level 1B 125m Native Science data, Validated Stage 1 V3-01

CAL_WFC_L1_125m-ValStage1-V3-01 data are Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Wide Field Camera (WFC) Level 1B 125m Native Science data, Validated Stage 1 Version 3-01. Data collection for this product is complete. Version 3.01 includes new metadata parameters and corrections to several minor software bugs. Specifically, the Orbit Number and Path Number metadata parameters are now included to facilitate improved subsetting capabilities. The primary WFC Level 1B data products are calibrated radiance and bidirectional reflectance registered to an Earth-based grid centered on the Lidar ground track. During the normal operation, the WFC acquires science data only during the daylight portions of the CALIPSO orbits. The WFC Level 1B 125 m Native Science data product provides WFC radiance and reflectance measurements across just the central 5 km swath at 125 m resolution. No spatial interpolation is performed. CALIPSO was launched on April 28, 2006 to study the impact of clouds and aerosols on the Earth's radiation budget and climate. It flies in the international A-Train constellation for coincident Earth observations. The CALIPSO satellite is comprised of three instruments, the Cloud-Aerosol LIdar with Orthogonal Polarization (CALIOP), the Imaging Infrared Radiometer (IIR), and the WFC. CALIPSO is a joint satellite mission between NASA and the French Agency, CNES.

CAL_WFC_L1_125m-ValStage1-V3-01 数据集系由云-气溶胶激光雷达与红外路径卫星观测（Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation，简称CALIPSO）宽视场相机（Wide Field Camera，简称WFC）一级B级125米原生科学数据构成，经过验证的1级版本3-01。该数据产品的采集工作已圆满完成。版本3.01新增了元数据参数，并对数个软件小错误进行了修正。特别是，轨道编号和路径编号的元数据参数已包含其中，以便增强子集功能。主要WFC一级B级数据产品包括经校准的辐射度和双向反射率，这些数据与以激光雷达地面轨迹为中心的地球基网格进行注册。在正常操作期间，WFC仅在CALIPSO轨道的白天部分采集科学数据。WFC一级B级125米原生科学数据产品提供了WFC辐射度和反射度测量值，这些测量值仅覆盖中央5公里宽的条带，分辨率为125米。未执行空间插值。CALIPSO卫星于2006年4月28日发射，旨在研究云和气溶胶对地球辐射收支和气候的影响。它在国际A-Train星座中进行同步地球观测。CALIPSO卫星由三个仪器组成：云-气溶胶激光雷达与正交极化（Cloud-Aerosol LIdar with Orthogonal Polarization，简称CALIOP）、成像红外辐射计（Imaging Infrared Radiometer，简称IIR）和WFC。CALIPSO是美国国家航空航天局（NASA）与法国国家空间研究中心（CNES）共同发起的卫星任务。
