gs: Gulf Stream position

Description Usage Source References Examples

Description

Monthly latitude and longitude of Gulf Stream position, averaged from 1973 to 1992, according to Drinkwater et al. 1994 (page 103), in the form of a list containing month, the numbers 1 through 12, longitude, the longitudes in degrees east, and latitude, a matrix of latitudes, with columns for months and rows for longitudes. The data were entered by hand by Dan Kelley, and may suffer errors resulting from typos and inaccurate reading of occasionally blurry digits.
