It seems that latitude is not 1 degree resolution. The ncdump of the file
is as follows

65.04243, 65.12708, 65.21143, 65.29546, 65.37913, 65.46243, 65.54534,
    65.62783, 65.70989, 65.7915, 65.87263, 65.95326, 66.03338, 66.11296,
    66.19199, 66.27044, 66.3483, 66.42554, 66.50217, 66.57814, 66.65345,
    66.72808, 66.80201, 66.87522, 66.9477, 67.01944, 67.09041, 67.1606,
