Input and Output data

Input Data

CyTRACK can read and directly process input data from ERA5 and WRF-ARW model by typying source=”ERA5” or source= “WRF” in the input file. Note that ERA5 input data must be downloaded with longitudes in 0-360 format. For other case of ERA5 data or other sources, please set source=”CUSTOM”.

CyTRACK is configured for tracking tropical cyclones (TC), extratropical cyclones (EC), Mediterranean Cyclones (MC), subtropical cyclones (SC) and tropical-like-cyclones (TLC)

CyTRACK output

It is a comma-delimited text format following a similar to the HURDAT2 dataset ( Landsea and Franklin (2013) ) suported by the U.S. National Hurricane Center (NHC)
