Model Output and Validation Data for Online Determination of GNSS Differential Code Biases using Rao-Blackwellized Particle Filtering

This dataset contains the outputs of 10 test runs of the A-CHAIM data assimilation model used to evaluate the performance of the bias estimation procedure used by the model. The 5-minute output files for each test run are included in a separate folder.

The IGS DCBs in SINEX format and the various global ionospheric maps used in the study are included.

This dataset also includes all of the processed GNSS data used in the study, which were used to generate the DCBs used in each test run.

The in-situ electron density measurements from DMSP as well as the ionosonde data from GIRO which were used to measure the performance are also included.

本数据集包含用于评估A-CHAIM数据同化模型（A-CHAIM data assimilation model）自身偏差估计流程性能的10次测试运行结果。各测试运行的5分钟级输出文件均存储于独立文件夹中。

本数据集收录了采用SINEX格式存储的IGS差分码偏差（Differential Code Biases, DCBs），以及本研究使用的各类全球电离层图。

本数据集同时包含本研究中使用的全部预处理全球导航卫星系统（Global Navigation Satellite System, GNSS）数据，这些数据用于生成各测试运行所需的差分码偏差（DCBs）。

本数据集还收录了用于性能评估的国防气象卫星计划（Defense Meteorological Satellite Program, DMSP）原位电子密度测量数据，以及GIRO电离层探测仪观测数据。
