Dataset of GraphCast/ML/GPT3 model estimated PWV using radiosonde/GNSS data

In the manuscript "Evaluation of Forecast-based Global GNSS Precipitable Water Vapor Retrieval using the AI-based Global Weather Forecast Model",  this data is the three models(GraphCast, GPT3 mode, and the stacked Machine-learning Model) output files used in the validation. The data files are archived by two types: Radiosonde validation results and ESSD validation results.
