CFSR wind speed data

17 January 2015   //   by admin   //   Data, News  //  Comments (0)
Climate Forecast System Reanalysis (CFSR) now available at Climate Wikience! The data are imported from NCDC NOAA

The temporal resolution of data is 1 hr while the spatial resolution is T382 Gaussian grid. Climate Wikience delivers regular latitude-longitude global grid with 0.25 deg x 0.25 deg resolution using bicubic interpolation.

CFSR does not direclty deliver wind speed, but eastward (u) and northward (v) wind speed vectors. The wind speed is calculated by Climate Wikience as square_root (u^2 + v^2).

Below is the CFSR wind speed at 10 meters above surface on the 28th of August, 2005. The hurricane Katrina was near its peak strength on that date. The isolines are contoured every 1 m/s (meters per second).

Satellite data on sea wind

16 January 2015   //   by admin   //   Data, News  //  Comments (0)
Blended sea wind data product from several satellites including QuikSCAT, SSMIs, TMI and AMSR-E. The product is gridded and has global coverage with 0.25 deg x 0.25 deg spatial resolution. The temporal resolution is 6 hours The data was imported from NOAA National Climatic Data Center

The product was derived from multiple satellite observations: DMSP SSMI F08, F10, F11, F13,F14 F15; TMI; QuikSCAT; AMSR-E while wind direction was taken from NCEP Reanalysis-2 (that is why the product is called “blended”).

Below is eastward wind speed for 10 meters above sea surface (u10m) on the 28th of August, 2005.
