ERS-2 C-band scatterometer data of Hurricane Isabel

A map of the wind field at the heart of Hurricane Isabel, using data acquired at 15.23 UTC on 17 September 2003 by the C-band scatterometer on board ESA's ERS-2 spacecraft. The map indicates wind direction and also wind velocity - the more lines on each bar, the highest the velocity. The data provides insight into the pressure system powering the hurricane.
