A comprehensive archive of Tropical cyclones vertical structure 2001–2018

Description

This data collection merges all the information available about Tropical Cyclones (TC) co-located, within a time range of 3 hours and a space window of 500 km, with Global Navigation Satellite Systems (GNSS) Radio Occultations (RO) profiles in the period 2001–2018.

We include the TC best-track data from the International Best Track Archive for Climate Stewardship (IBTrACS), the bending angle, refractivity, temperature, pressure and specific humidity (with 100-meter sampling from the surface up to 40 km) from the GNSS RO data processed by the Wegener Center for Climate and Global Change (WEGC) with the Occultation Processing System (OPS) version 5.6.2, and the WEGC climatologies of bending angle, temperature and specific humidity [1].

Variables

TC best track, Bending angle, Refractivity, Temperature, Pressure, Specific humidity, Bending angle climatology, Temperature climatology, Relative humidity climatology

Keywords

Radio Occultation, Global Navigation Satellite System, Global Positioning System, Tropical cyclone, Severe tropical cyclone, Hurricane, Typhoon, Extratropical cyclone, Storm, Best-track
