Title: Synchronous wind, wave and rain dataset from Sentinel-1 during tropical cyclones in 2016-2024

Description: Datasets consisting of wind speed, wind direction, significant wave height, and rain rate data from 357 Sentinel-1 observations of tropical cyclines during 2016-2024.

Format: Each Sentinel-1 SAR image of a typhoon is stored as an individual NetCDF file. 

File naming: The files are named S1-TCname-yyyymmddThhMMss-V1.nc, where S-1 indicates the satellite; TCname is the identifier based on IBTrACS naming convention; yyyy, mm and dd represent the year, month and day of image; hhMMss is the hour accurate to second; and V1 denotes Version 1

Methodological Information
=========================================================
Method description: The  dataset generated using an XGBoost machine learning model (see Shao et al., Synchronous wind, wave and rain dataset from Sentinel-1 during tropical cyclones in 2016-2024, under review).  Further details on the algorithm can be found in the manuscript. 

Software: All data was produced using Python 3.9 or later. The file format of the dataset has been chosen to ensure conformity with oceanographic data storage standards .


Validation: The dataset has been validated in the manuscript.

Column names: The entries of each of the .nc-files is as follows (copied from Shao et al - Synchronous wind, wave and rain dataset from Sentinel-1 during tropical cyclones in 2016-2024),
each NetCDF file of Sentinel-1 observed tropical cyclones contains the following data:
