Dataset of Tropical Cyclone for Image-to-intensity Regression (TCIR)

Boyo Chen, BuoFu Chen and Hsuan-Tien Lin

TCIR collects Tropical Cyclone (TC) data from 4 channels of satellite images. TCIR aims to act as a benchmark dataset to help data scientists fairly evaluate the performance of TC intensity prediction models.

Sources

Satellite observations comprising TCIR are collected from two open sources:

Labels

We used the best-tracks from Joint Typhoon Warning Center (JTWC) for TCs in western North Pacific (WP); the best-tracks from the revised Atlantic hurricane database (HURDAT2) for TCs in eastern North Pacific (EP) and Atlantic Ocean (AL) from 2003 to 2016.

The TC information provided in TCIR includes:

Note that these values are tuned and finalized afterward based on all observation that is available. Thus, they are very different from the real-time estimations in meaning. While the best-track information can be taken as ground truth, they are still some "estimation" in nature and can suffer from some inherent noise.

In addition to the intensity, we also provided another remarkable TC structure parameter, the size. TC size is closely related to the impacts on the economy/society from a TC. We encourage the community to tackle the TC size prediction task

Usage

We provide an HDF5 format file for people to easily access the whole organized dataset.

Example: Loading TCIR dataset with python.

import numpy as np
import pandas as pd
import h5py

data_path = "TCIR.h5"

# load "info" as pandas dataframe
data_info = pd.read_hdf(data_path, key="info", mode='r')

# load "matrix" as numpy ndarray, this could take longer times
with h5py.File(data_path, 'r') as hf:
    data_matrix = hf['matrix'][:]
