The satellite analysis dataset of tropical cyclone size (version 3.0) includes 6-hour position, intensity, and size information of all tropical cyclones observed in the Western North Pacific. The position and intensity data of tropical cyclones are derived from the best track data provided by the China Meteorological Administration (https://tcdata.typhoon.org.cn/zjljsjj.html). The size information comprises the maximum wind speed radius, and the wind radii of 34, 50, and 64 kt in the NE, SE, SW, and NW quadrants. The spatial coverage extends north of the equator, west of 180°, and encompasses the South China Sea. The dataset spans from 1981 to 2020.

Intensity category according to the Chinese
National Standard for Grade of Tropical Cyclones
(which has been used since 15 June 2006):
0 –– Weaker than Tropical Depression or unknown intensity; 1 –– Tropical Depression (TD: 10.8–17.1 m/s); 2 –– Tropical Storm (TS:17.2–24.4 m/s); 3 –– Severe Tropical Storm (STS: 24.5–32.6 m/s); 4 –– Typhoon (TY: 32.7–41.4 m/s); 5 –– Severe Typhoon (STY: 41.5–50.9 m/s); 6 –– Super Typhoon (SuperTY: ≥51.0 m/s); 9 –– Extratropical Cyclone (ET) stage. |

The retrieved Tropical Cyclone Size Dataset covers tropical cyclones that developed over the western North Pacific and captured by satellites. The basin is to the north of the equator and to the west of 180°E, and includes the South China Sea (SCS).
The present version (2.0) of the dataset includes 6-hourly track, intensity analyses and retrieval size between 1980 and 2016 for TCs with intensities of and above tropical storms (MSW>17.2m/s).
