SMOS Tropical Cyclone Wind Radii Fixes WRF

Data

DOWNLOAD DATA Dataset available upon authorization from external site.

blue arrow DESCRIPTION

The SMOS WRF product is available in Near Real Time to support tropical cyclones (TC) forecasts.

It is generated within 4 to 6 hours from sensing from the SMOS L2 swath wind speed products, in the so-called "Fix (F-deck)" format compatible with the US Navy's ATCF (Automated Tropical Cyclone Forecasting) System.

The SMOS WRF "fixes" to the best-track forecasts contain: the SMOS 10-min maximum-sustained winds (in knots) and wind radii (in nautical miles) for the 34 kt (17 m/s), 50 kt (25 m/s) and 64 kt (33 m/s) winds per geographical storm quadrants, and for each SMOS pass intercepting a TC in all the active ocean basins.
