CALIPSO Wide Field Camera Level 1B 125m Native Science data, Validated Stage 1 V3-02

CAL_WFC_L1_125m-ValStage1-V3-02 data are Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Wide Field Camera (WFC) Level 1B 125 m Native Science data, Validated Stage 1 Version 3-02. Data collection for this product is ongoing. Version 3.02 represents a transition of the Lidar, Imaging Infrared Radiometer (IIR), and WFC processing and browse code to a new cluster computing system. No algorithm changes were introduced, and very minor changes were observed between V3.01 and V3.02 as a result of the compiler and computer architecture differences. 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 1 km Native Science grid covers the full 61 km swath centered on the Lidar track. The 125 m Native Science grid contains only the central 5 km wide high resolution portion of the WFC swath. Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (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), IIR, and WFC. CALIPSO is a joint satellite mission between NASA and the French Agency, CNES.

CAL_WFC_L1_125m-ValStage1-V3-02 数据集为基于云气激光雷达与红外探测卫星观测（Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation，简称CALIPSO）的宽场相机（Wide Field Camera，简称WFC）Level 1B 125米原生科学数据，经过验证的1级版本3-02。该数据产品的采集工作仍在进行中。版本3.02标志着激光雷达、成像红外辐射计（Imaging Infrared Radiometer，简称IIR）和WFC处理及浏览代码向新的集群计算系统的过渡。未引入新的算法变更，由于编译器和计算机架构的差异，V3.01与V3.02之间仅观察到细微的变化。主要的WFC Level 1B数据产品是经过校准的辐射亮度以及双向反射率，它们被注册到以激光雷达地面轨迹为中心的地球网格上。在正常操作中，WFC仅在CALIPSO轨道的白天部分采集科学数据。1公里原生科学网格覆盖了以激光雷达轨迹为中心的完整61公里波段。125米原生科学网格仅包含WFC波段中央5公里宽的高分辨率部分。云气激光雷达与红外探测卫星观测（Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations，简称CALIPSO）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。它作为国际A-Train星座的一部分，进行同步地球观测。CALIPSO卫星由三个仪器组成，即正交极化云气激光雷达（Cloud-Aerosol LIdar with Orthogonal Polarization，简称CALIOP）、IIR和WFC。CALIPSO是NASA与法国国家空间研究中心（CNES）的联合卫星任务。
