Data Format

Data is loaded from the TempestExtremes track files by the tempest_helper.get_trajectories() function and is returned as a list of dictionaries. Each dictionary represents an individual trajectory and contains the key-value pairs shown below; most values are lists of consecutive points in the trajectory.

Key name	Value type	Value description
length	int	The number of points in the trajectory generated by TempestExtremes [1]
lon	list	The longitude points, with each point being a float of the decimal degree longitude point
lat	list	The longitude points, with each point being a float of the decimal degree latitude point
year	list	The year points, with each point being the integer year
month	list	The month points, with each point being the integer month
day	list	The day points, with each point being the integer day of the month
step	list	The integer step number, with 1 being the first time point in the data file

[1] Any gaps in the trajectory are interpolated over and so there may be more points in the trajectory than are listed in the length value. The actual number of points can be found with len(storm['step']).
