Title: STORM Climate Change synthetic tropical cyclone tracks

Description: Each seperate .txt-file contains 1,000 years of synthetic tropical cyclone tracks, generated using the STORM algorithm.

Format: for every array (time step of a tropical cyclone), the entries are comma-seperated. 

File naming: The files are named STORM_DATA_(model name)_(Basin ID)_1000_YEARS_(index)_IBTRACSDELTA.txt. The Basin IDs can be found in the description. "index" ranges from 0-9. 
The Model names are 1) CMCC-CM2-VHR4 2) CNRM-CM6-1-HR 3)EC-Earth3P-HR 4)HadGEM3-GC31-HM

Methodological Information
=========================================================
Method description: the synthetic tracks were generated using the fully statistical STORM algorithm (see Bloemendaal et al 2020). The climate change signal was added following the newly developed delta method, this is described
in Bloemendaal et al "Low-probability tropical cyclone events under climate change" (in preparation). 

Software: All data was produced in Python 3.6.1 on the SURFsara Lisa Computer Cluster. The file format of the datasets has been chosen such that they can be opened and 
analyzed in a wide variety of computer programs.


Validation: The model is validated in Bloemendaal et al (2020), the climate change dataset is validated in Bloemendaal et al (in prep)

Column names: The entries of each of the .txt-files is as follows (copied from Bloemendaal et al 2020),
for every time step of a tropical cyclone:


Entry	Variable name			Unit		Notes on variable

2	Month				-	
3	TC number			-		For every year; starts at 0. 
4	Time step			3-hourly	For every TC; starts at 0.
5	Basin ID			-		0=EP, 1=NA, 2=NI, 3=SI, 4=SP, 5=WP
6	Latitude			Deg		Position of the eye.
7	Longitude			Deg		Position of the eye. Ranges from 0-360°, with prime meridian at Greenwich.
8	Minimum pressure		hPa
