Ten-meter east and north wind speeds are acquired from the COADS data set [Woodruff
et al., 1998]. The COADS data sets are comprised of in situ observations of wind speed,
atmospheric pressure, water/air temperature, etc., mainly from ships of opportunity, that have
been acquired, quality-controlled, and summarized statistically on a monthly basis on 1 degree
squares. These monthly summary groups (MSGs) from the years 1975-97 are taken for the
northwest Atlantic region and split into months. The resulting data are block averaged onto a
1X1 degree grid (using data for which the sample size is greater than 20), smoothed with a 9-point
Laplacian filter, and then linearly interpolated onto both the large-scale and climatology model
grids for computations.
