In icelocationmode=2 there are 120 manually predefined grid points where ! watercaptag is true (for the 64x48 resolution). The grid cells corners ! coordinates in latitude and longitude are written below. With this ! routine, we check if the grid cell center is in between any of those ! points. If so, watercaptag = true. latedge(:,1)=(/ & 88.125, 84.375, 84.375, 84.375, 84.375, 84.375,84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, & 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, & 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, & 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, & 80.625, 80.625, 76.875, 76.875, 76.875, 76.875, 76.875, 76.875, & 76.875, 76.875, 76.875, 76.875, 76.875, 76.875, 76.875, 73.125, & 73.125, 73.125, 73.125, 73.125, 73.125, 73.125, 73.125, 73.125/) latedge(:,2)=(/ & 90. , 88.125, 88.125, 88.125, 88.125, 88.125,88.125, 88.125, & 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, & 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, & 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, & 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, & 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, & 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, & 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, 88.125, & 88.125, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, 84.375, & 84.375, 84.375, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, & 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 80.625, 76.875, & 76.875, 76.875, 76.875, 76.875, 76.875, 76.875, 76.875, 76.875/) lonedge(:,1)=(/ &-180. , -180. , -177.1875, -171.5625,-165.9375, -160.3125, &-154.6875, -149.0625, -143.4375, -137.8125, -132.1875,-126.5625, &-120.9375, -115.3125, -109.6875, -104.0625, -98.4375, -92.8125, & -87.1875, -81.5625, -75.9375, -70.3125, -64.6875, -59.0625, & -53.4375, -47.8125, -42.1875, -36.5625, -30.9375, -25.3125, & -19.6875, -14.0625, -8.4375, -2.8125, 2.8125, 8.4375, & 14.0625, 19.6875, 25.3125, 30.9375, 36.5625, 42.1875, & 47.8125, 53.4375, 59.0625, 64.6875, 70.3125, 75.9375, & 81.5625, 87.1875, 92.8125, 98.4375, 104.0625, 109.6875, & 115.3125, 120.9375, 126.5625, 132.1875, 137.8125, 143.4375, & 149.0625, 154.6875, 160.3125, 165.9375, 171.5625,-132.1875, &-126.5625, -120.9375, -115.3125, -109.6875, -104.0625, -98.4375, & -92.8125, -87.1875, -81.5625, -75.9375, -30.9375, -25.3125, & -19.6875, -14.0625, -8.4375, -2.8125, 2.8125, 8.4375, & 14.0625, 19.6875, 25.3125, 30.9375, 36.5625, 42.1875, & 47.8125, 53.4375, 59.0625, 64.6875, 70.3125, 75.9375, & 81.5625, 87.1875, -149.0625, -137.8125, -126.5625,-115.3125, & -8.4375, 2.8125, 14.0625, 115.3125, 126.5625, 137.8125, & 149.0625, 160.3125, 171.5625, -180. , -132.1875,-109.6875, & 98.4375, 109.6875, 132.1875, 143.4375, 154.6875,165.9375/) lonedge(:,2)=(/ & 180. , -180. , -171.5625, -165.9375,-160.3125, -154.6875, &-149.0625,-143.4375, -137.8125, -132.1875, -126.5625, -120.9375, &-115.3125,-109.6875, -104.0625, -98.4375, -92.8125, -87.1875, & -81.5625, -75.9375, -70.3125, -64.6875, -59.0625, -53.4375, & -47.8125, -42.1875, -36.5625, -30.9375, -25.3125, -19.6875, & -14.0625, -8.4375, -2.8125, 2.8125, 8.4375, 14.0625, & 19.6875, 25.3125, 30.9375, 36.5625, 42.1875, 47.8125, & 53.4375, 59.0625, 64.6875, 70.3125, 75.9375, 81.5625, & 87.1875, 92.8125, 98.4375, 104.0625, 109.6875, 115.3125, & 120.9375, 126.5625, 132.1875, 137.8125, 143.4375, 149.0625, & 154.6875, 160.3125, 165.9375, 171.5625, 177.1875, -126.5625, &-120.9375,-115.3125, -109.6875, -104.0625, -98.4375, -92.8125, & -87.1875, -81.5625, -75.9375, -70.3125, -25.3125, -19.6875, & -14.0625, -8.4375, -2.8125, 2.8125, 8.4375, 14.0625, & 19.6875, 25.3125, 30.9375, 36.5625, 42.1875, 47.8125, & 53.4375, 59.0625, 64.6875, 70.3125, 75.9375, 81.5625, & 87.1875, 92.8125, -143.4375, -132.1875, -120.9375, -109.6875, & -2.8125, 8.4375, 19.6875, 120.9375, 132.1875, 143.4375, & 154.6875, 165.9375, 177.1875, -177.1875, -126.5625, -104.0625, & 104.0625, 115.3125, 137.8125, 149.0625, 160.3125,171.5625/) watercaptag_glo(:) = .false.
