Abstract. Polarimetric Radio Occultations (PRO) represent an augmentation of the standard Radio Occultation (RO) technique that provides precipitation and clouds vertical information along with the standard thermodynamic products. A combined dataset that contains both the PRO observable and the RO standard retrievals, the resPrf, has been developed with the aim to foster the use of these unique observations and to fully exploit the scientific implication of having information about vertical cloud structures with intrinsically collocated thermodynamic state of the atmosphere. This manuscript describes such dataset and provides detailed information on the processing of the observations. The procedure followed at UCAR to combine both H and V observations to generate the equivalent profiles as in standard RO missions is described in detail, and the obtained refractivity is shown to be of equivalent quality as that from TerraSAR-X. The steps of the processing of the PRO observations are detailed, derived products such as the top-of-the-signal are described, and validation is provided. Furthermore, the dataset contains the simulated ray-trajectories for the PRO observation, and co-located information with global satellite-based precipitation products, such as merged rain rate retrievals or passive microwave observations. These co-locations are used for further validation of the PRO observations and they are also provided within the resPrf profiles for additional use. It is also shown how accounting for external co-located information can improve significantly the effective PRO horizontal resolution, tackling one of the challenges of the technique.

用于科学应用的 PAZ 极化射电掩星研究数据集


摘要。极化射电掩星 (PRO) 是标准射电掩星 (RO) 技术的增强，可提供降水和云垂直信息以及标准热力学产品。开发了一个包含 PRO 可观测值和 RO 标准检索的组合数据集 resPrf，其目的是促进这些独特观测值的使用，并充分利用具有本质上并置热力学的垂直云结构信息的科学含义大气状态。本手稿描述了此类数据集并提供了有关观察处理的详细信息。详细描述了 UCAR 所遵循的结合 H 和 V 观测以生成与标准 RO 任务中等效的轮廓的程序，并且所获得的折射率与 TerraSAR-X 的折射率具有相同的质量。详细描述了 PRO 观测值的处理步骤，描述了诸如顶部信号之类的衍生产品，并提供了验证。此外，该数据集包含 PRO 观测的模拟射线轨迹，以及与全球卫星降水产品的共定位信息，例如合并降雨率反演或被动微波观测。这些共置用于进一步验证 PRO 观测结果，并且还在 resPrf 配置文件中提供它们以供其他使用。它还展示了如何考虑外部共址信息可以显着提高有效的 PRO 水平分辨率，从而解决该技术的挑战之一。
