CALIPSO Lidar Level 3 Stratospheric Aerosol Profiles Standard V1-00

CAL_LID_L3_Stratospheric_APro-Standard-V1-00 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Lidar Level 3 Stratospheric Aerosol Profiles Standard Version 1-00 data product. This data product was collected using the Cloud-Aerosol LIdar with Orthogonal Polarization (CALIOP) instrument. Data collection for this product is ongoing.

The CALIPSO Lidar Level 3 stratospheric aerosol reports global distributions of 532nm total attenuated backscatter, extinction, attenuated scattering ratios, and stratospheric aerosol optical depths on a uniform spatial grid. All level 3 parameters are derived from the CALIPSO version 4 level 1 and level 2 5 km merged layer and version 3 level 2 polar stratospheric cloud data products, with a temporal averaging of one month. The primary outputs are reported in terms of 1) background only and 2) all aerosol. For background only all features identified by the level 2 algorithms have been removed. For all aerosol only aerosols layers are considered, while clouds and polar stratospheric clouds are removed.

CALIPSO was launched on April 28, 2006 and continues to collect data necessary 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 comprises three instruments, CALIOP, Imaging Infrared Radiometer (IIR), and Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency, CNES.

CAL_LID_L3_Stratospheric_APro-Standard-V1-00为云气溶胶激光雷达与红外路径探测器卫星观测（Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation，简称CALIPSO）激光雷达三级平流层气溶胶廓线标准版1-00数据产品。该数据产品采用云气溶胶激光雷达正交极化（Cloud-Aerosol LIdar with Orthogonal Polarization，简称CALIOP）仪器收集，数据收集工作持续进行。CALIPSO激光雷达三级平流层气溶胶报告在全球范围内以统一的空间网格展示了532nm总衰减后向散射、消光、衰减散射比和平流层气溶胶光学厚度。所有三级参数均源自CALIPSO版本4的一级和二级5公里合并层以及版本3的二级极地平流层云数据产品，并进行了为期一个月的时间平均。主要输出包括1）仅背景和2）所有气溶胶。在仅背景的情况下，已移除由二级算法识别的所有特征；在所有气溶胶的情况下，仅考虑气溶胶层，同时移除云和极地平流层云。CALIPSO卫星于2006年4月28日发射，持续收集研究云和气溶胶对地球辐射收支和气候影响所必需的数据。它作为国际A-Train星座的一部分，进行同步地球观测。CALIPSO卫星包括三个仪器：CALIOP、成像红外辐射计（Imaging Infrared Radiometer，简称IIR）和广域相机（Wide Field Camera，简称WFC）。CALIPSO是NASA与法国国家空间研究中心（Centre National d'Études Spatiales，简称CNES）联合发射的卫星任务。
