Problems with FEB 1945 grid - Problems with this specific grid have been reported by users. Visual inspection of contours of the field confirm problems. Comparisions with SLP data from Russia (ds012.0) suggested a possible fix. Grid points at odd longitudes (15N, 25N, etc.) were shifted 10 degrees (2 grid points) to the west (ie data at i=3 was moved to i=1, etc.). The resulting field after this change looks much more reasonable and compares favorably with the Russian field. Note that the values at at 80N,155W, 150W, and 145W are almost certainly incorrect for this month. As of 20AUG1998 no changes have been made to the data fields. Erroneous data point at 65N,140W This problem was reported by users also. Comparing this point to surrounding points indcates some osrt of problem in the period March 1902 through July 1909, although 2 months in this period (jan and feb 1903) look they may be OK. As of 20AUG1998 no changes have been made to the data fields.
