Phase 2 - Buoy/Satellite Wind Comparison

Up one level
Comparison between buoy and satellite (ASCAT and QuikSCAT) wind characteristics.
ASCAT and Buoy 10m Wind Speed Comparison
Plots of the ASCAT satellite measurements of wind speed at 10m above sea level against the extrapolations of wind speeds from buoy measurements. The buoy data represents extrapolations of wind speed at 10m from buoy data taken 3-5m above sea level using the Large and Pond, Monin Obukhov, and Power Law interpolation schemes. The data is represented as monthly averages for the years 2008-2010. For certain months, the buoys failed to take measurements of key variables for half or more of the days in that month over 2008-2010. The monthly averages for such months are excluded from the plot.
ASCAT and Buoy Wind Stress Comparison
Plots of the wind stress at 10m above sea level. The comparison is between measurements made by the ASCAT directly at 10m and extrapolations of 10m high wind speeds using buoy data taken at 3-5m above sea level. The Large and Pond and Monin Obukhov extrapolation schemes were used. The data is shown as monthly averages for the years 2008-2010. For certain months, the buoys failed to take measurements of key variables for half or more of the days in that month over 2008-2010. The monthly averages for such months are excluded from the plot.
QuikSCAT and Buoy 10m Wind Speed Comparison
Plots of the QuikSCAT satellite measurements of wind speed at 10m above sea level versus the wind speed interpolations of the buoy data. The buoy data represents the wind speed measurements taken at 3-5m above sea level interpolated up to 10m using the Large and Pond, Monin Obukhov, and Power Law interpolation schemes. The data is represented as monthly averages across 2003-2009. For certain months, the buoys failed to take measurements of key variables for half or more of the days in that month over 2003-2009. The monthly averages for such months are excluded from the plot.
Satellite and Buoy Summary
The mean differences between the QuickSCAT, ASCAT, and buoy wind speed and stress monthly averages are provided as a means of comparing the satellite and buoy data.
