South Pole Keeling network (SIO) Column 1 is the average sample date; columns 2 and 3 give sample identification numbers; column 4 is the measured value, column 5 is the estimated measurement error. Column 6 gives the temporally smoothed data obtained by the curve fitting technique of Cleveland(1), and column 7 gives the residuals from that curve. Column 8 gives the results of fitting 2 harmonics to column 7, to obtain the seasonal component. Column 9 is the deseasonalized trend (data minus seasonal component); column 10 is the sum of the long-term trend and the seasonal component, and column 11 is the departure of the data from column 10. 1 2 3 4 5 6 7 8 9 10 11 ave sample sample GrA DELTA error trend detrended seasonal deseasonalized date number number 14C (o/oo) (o/oo) fit fit data total fit residuals Oct/24/1984 22556 13196 207.7 3.5 206.6 1.1 1.0 206.7 207.6 0.1 Oct/24/1984 22556 13201 204.4 3.8 206.6 -2.2 1.0 203.5 207.6 -3.2 Mar/1/1985 22507 11787 205.2 5.8 204.0 1.1 1.3 203.8 205.4 -0.2 Apr/15/1985 22524 11862 204.9 3.1 203.1 1.8 -0.6 205.5 202.5 2.4 Apr/15/1985 22524 13174 200.9 3.5 203.1 -2.2 -0.6 201.5 202.5 -1.6 May/31/1985 22431 11521 205.9 3.8 202.2 3.7 -2.2 208.0 200.0 5.9 Jul/16/1985 22492 11770 204.8 5.8 201.2 3.6 -2.5 207.3 198.8 6.1 Jul/16/1985 22492 11778 199.2 5.9 201.2 -2.0 -2.5 201.7 198.8 0.5 Aug/31/1985 22461 11705 196.8 3.5 200.3 -3.4 -1.3 198.2 198.9 -2.1 Aug/31/1985 22461 11758 199.0 5.8 200.3 -1.2 -1.3 200.3 198.9 0.1 Oct/16/1985 22531 11882 198.1 3.3 199.1 -1.0 0.6 197.5 199.8 -1.6 Oct/16/1985 22531 13170 196.8 3.6 199.1 -2.3 0.6 196.2 199.8 -3.0 Jan/14/1986 22521 11861 197.4 3.0 196.9 0.5 2.5 194.9 199.4 -2.0 Jan/30/1986 22505 11785 201.1 5.8 196.6 4.5 2.2 198.9 198.8 2.3 Feb/24/1986 22541 11891 193.5 3.1 196.0 -2.4 1.5 192.0 197.5 -4.0 Mar/24/1986 22494 11767 197.4 5.8 195.4 2.1 0.4 197.0 195.8 1.7 Apr/23/1986 22469 11700 194.9 2.7 194.8 0.1 -0.9 195.8 193.9 1.0 May/23/1986 22479 11719 190.1 2.7 194.2 -4.1 -1.9 192.1 192.3 -2.2 Jun/23/1986 22527 11877 196.6 3.3 193.0 3.6 -2.5 199.1 190.5 6.1 Jul/24/1986 22471 11714 189.6 2.7 192.0 -2.3 -2.4 192.0 189.6 0.0 Aug/23/1986 22464 11701 191.3 3.1 191.0 0.3 -1.6 192.9 189.4 1.9 Sep/24/1986 22528 11868 194.9 3.0 190.0 4.8 -0.3 195.2 189.7 5.2 Nov/23/1986 22448 11548 186.7 3.8 187.9 -1.2 2.0 184.7 189.8 -3.1 Dec/23/1986 22454 11570 190.6 3.8 186.7 3.9 2.5 188.1 189.2 1.4 Jan/15/1987 22429 11542 186.4 3.9 185.8 0.6 2.5 183.9 188.2 -1.8 Jan/15/1987 22429 11748 184.3 5.8 185.8 -1.4 2.5 181.9 188.2 -3.9 Jan/15/1987 22540 11888 186.5 3.2 185.8 0.7 2.5 184.0 188.2 -1.8 Feb/15/1987 22535 11881 184.7 3.1 184.6 0.1 1.8 182.8 186.4 -1.7 Feb/15/1987 22535 13172 187.7 3.5 184.6 3.1 1.8 185.8 186.4 1.3 Mar/31/1987 22506 11786 186.7 5.7 183.2 3.5 0.1 186.6 183.4 3.4 May/16/1987 22447 11560 178.4 3.9 182.5 -4.0 -1.7 180.2 180.7 -2.3 May/16/1987 22447 11691 179.9 2.7 182.5 -2.6 -1.7 181.6 180.7 -0.9 Jun/21/1987 22473 11715 178.7 2.6 182.1 -3.3 -2.5 181.2 179.6 -0.9 Jun/21/1987 22473 11775 177.9 5.7 182.1 -4.2 -2.5 180.4 179.6 -1.7 Aug/16/1987 22510 11798 176.6 5.9 181.4 -4.8 -1.8 178.5 179.6 -2.9 Aug/16/1987 22510 13169 178.0 3.5 181.4 -3.4 -1.8 179.8 179.6 -1.6 Sep/23/1987 22532 11885 181.6 3.1 180.9 0.8 -0.4 182.0 180.5 1.2 Nov/8/1987 22550 13187 187.1 3.4 180.2 6.9 1.5 185.6 181.7 5.4 Dec/20/1987 22437 11526 185.0 3.7 179.5 5.5 2.5 182.6 182.0 3.0 Mar/10/1988 22456 11688 177.5 2.7 177.7 -0.2 1.0 176.5 178.7 -1.2 Apr/23/1988 22452 11572 177.3 3.7 176.7 0.6 -0.9 178.2 175.8 1.5 Apr/23/1988 22452 11694 176.9 2.6 176.7 0.2 -0.9 177.8 175.8 1.1 Aug/25/1988 22529 11875 171.3 3.0 172.7 -1.4 -1.5 172.9 171.2 0.1 Nov/29/1988 22537 11886 172.5 3.0 169.0 3.5 2.1 170.3 171.1 1.4 Dec/17/1988 22458 11569 173.9 4.9 168.3 5.6 2.5 171.4 170.7 3.2 Jun/1/1989 22898 10989 160.1 6.9 162.6 -2.5 -2.2 162.2 160.4 -0.3 Jul/18/1989 22534 11883 152.2 3.0 161.0 -8.8 -2.4 154.6 158.5 -6.4 Jul/18/1989 22534 13177 148.4 3.3 161.0 -12.6 -2.4 150.8 158.5 -10.1 Sep/17/1989 22483 11729 153.7 2.7 159.1 -5.4 -0.6 154.4 158.5 -4.8 Sep/17/1989 22483 11762 156.8 5.5 159.1 -2.4 -0.6 157.4 158.5 -1.7 Oct/14/1989 22902 10998 153.9 6.9 158.2 -4.3 0.5 153.4 158.7 -4.8 Nov/5/1989 22901 10997 161.4 7.0 157.6 3.7 1.4 159.9 159.0 2.3 Dec/10/1989 22468 11698 165.3 2.6 156.8 8.5 2.4 162.9 159.2 6.1 Feb/12/1990 22470 11717 152.2 2.7 155.7 -3.5 1.9 150.3 157.6 -5.4 Mar/9/1990 22451 11554 161.1 3.7 155.2 6.0 1.0 160.1 156.2 4.9 Apr/11/1990 22533 11887 157.1 3.1 154.7 2.4 -0.4 157.5 154.3 2.8 Jun/11/1990 22419 11537 154.1 3.6 153.5 0.6 -2.4 156.5 151.1 3.0 Jul/10/1990 22435 11522 153.7 3.7 152.8 0.9 -2.5 156.2 150.3 3.4 Aug/14/1990 22520 11859 148.5 2.9 151.5 -3.0 -1.9 150.4 149.6 -1.1 Oct/11/1990 22424 11533 154.4 3.7 149.5 4.9 0.4 154.0 149.9 4.5 Nov/10/1990 22450 11563 143.4 3.6 148.4 -5.0 1.6 141.8 150.0 -6.6 Dec/8/1990 22422 11532 148.9 3.6 147.4 1.5 2.3 146.6 149.7 -0.8 Dec/29/1990 22896 10992 152.7 6.9 146.6 6.0 2.5 150.1 149.2 3.5 Feb/7/1991 22425 11541 137.6 3.6 145.2 -7.6 2.0 135.6 147.3 -9.7 Mar/8/1991 22438 11524 141.7 3.7 144.2 -2.5 1.1 140.7 145.3 -3.6 May/8/1991 22554 11902 141.5 3.1 142.1 -0.6 -1.5 143.0 140.6 0.9 Jun/9/1991 22449 11567 136.2 3.7 141.0 -4.7 -2.3 138.5 138.6 -2.4 Aug/24/1991 22903 10999 139.2 6.8 138.3 0.9 -1.6 140.8 136.7 2.5 Nov/23/1991 22463 11708 136.7 2.6 135.1 1.5 2.0 134.7 137.1 -0.5 Jan/9/1992 22502 11734 137.4 2.6 133.5 3.9 2.5 134.9 136.1 1.4 (1) Cleveland, W.S. 1979.
