The QuikSCAT Tropical Cyclone Radial Structure Dataset (QSCAT-R) consists of tropical cyclone (TC) data that have been collected and processed from the following sources:

  • NASA JPL QuikSCAT Tropical Cyclone database, and
  • IBTrACS Best Track (BT) Dataset.

The current version of the dataset includes tropical cyclones from all global ocean basins for the years 1999-2009, during which the QuikSCAT satellite was operational.

The dataset contains QuikSCAT-derived data for the radial structure of tropical cyclones, including:

  • radial profiles of total windspeed and its azimuthal and radial components,
  • canonical wind radii (64 kt, 50 kt, 34 kt, 12 ms-1) estimated from the radial profile of the azimuthal wind and total wind,
  • radial profile of a quantity proportional to rain rate, and
  • radial profile of collocated SSM/I cloud liquid data, when available.

Example code to read the QSCAT-R Dataset

An example code set is provided to aid users in reading the dataset products. The example code reads in all of the data parameters for one storm (Katrina 2005) into memory and then illustrates how to generate plots that show the symmetric and asymmetric winds, as well as the evolution of winds over time. Users may adapt this code to undertake new analysis tasks or to translate the data into a different format.

The example code is written in Matlab, a powerful commercial data & visualization language similar to IDL. In order to use the example code, a user must first download and install Matlab on their computer. Users can also use any other software package that can read NetCDF files.

The code is provided as a zip file. Please click the link below, save it to the desired location, then unzip it in the location you wish to use it, (e.g. 'unzip QSCAT-R_MATLAB_Example.zip').
