EarthCARE ESA L2 Products for Cal/Val Users

This EarthCARE collection is restricted, and contains the following data products:

· Level 2a: Single-Instrument Geophysical Products

These products are derived from individual instrument data onboard EarthCARE. They provide detailed geophysical parameters and properties specific to each instrument's capabilities for example cloud and aerosol properties derived solely from radar or lidar measurements, offering high-resolution insights into atmospheric phenomena.

· Level 2b: Synergistic Geophysical Products

Level 2b products leverage data from multiple EarthCARE instruments to generate comprehensive, synergistic geophysical datasets. By combining measurements from instruments like radar, lidar, and radiometers, these products offer a more integrated view of cloud-aerosol interactions and atmospheric dynamics. Synergistic products provide enhanced accuracy and depth compared to single-instrument outputs, enabling detailed studies of complex atmospheric processes.

本EarthCARE数据集为受限数据集，包含以下数据产品：

· 2a级：单仪器地球物理产品

此类产品源自EarthCARE搭载的单台仪器观测数据，可提供与各仪器性能匹配的详细地球物理参数与特性。例如仅通过雷达或激光雷达（LiDAR）测量反演得到的云与气溶胶特性，可为大气现象研究提供高分辨率的解析视角。

· 2b级：协同地球物理产品

2b级产品借助EarthCARE搭载的多台仪器数据，生成综合性协同地球物理数据集。通过融合雷达、激光雷达（LiDAR）与辐射计等仪器的观测数据，此类产品可更为全面地展现云-气溶胶相互作用与大气动力学过程。相较于单仪器反演结果，协同产品的精度与解析深度均得到提升，可支撑复杂大气过程的精细化研究。
