************ USE OF CMDL CCGG DATA **************** These data are made freely available to the public and the scientific community in the belief that their wide dissemination will lead to greater understanding and new scientific insights. The availability of these data does not constitute publication of the data. We rely on the ethics and integrity of the user to assure that CMDL receives fair credit for our work. If the data are obtained for potential use in a publication or presentation, CMDL should be informed at the outset of the nature of this work. If the CMDL data are essential to the work, or if an important result or conclusion depends on the CMDL data, co-authorship may be appropriate. This should be discussed at an early stage in the work. Manuscripts using the CMDL data should be sent to CMDL for review before they are submitted for publication so we can insure that the quality and limitations of the data are accurately represented. Contact: Tom Conway (303 497 6681; thomas.j.conway@noaa.gov) **************** RECIPROCITY AGREEMENT **************** Use of these data implies an agreement to reciprocate. Laboratories making similar measurements agree to make their own data available to the general public and to the scientific community in an equally complete and easily accessible form. Modelers are encouraged to make available to the community, upon request, their own tools used in the interpretation of the CMDL data, namely well documented model code, transport fields, and additional information necessary for other scientists to repeat the work and to run modified versions. Model availability includes collaborative support for new users of the models. *********************************************************** N15 1986 12 346.90 N15 1987 01 347.51 N15 1987 02 348.77 N15 1987 03 350.35 N15 1987 04 351.58 N15 1987 05 352.53 N15 1987 06 352.24 N15 1987 07 350.08 N15 1987 08 347.72 N15 1987 09 346.61 N15 1987 10 346.93 N15 1987 11 348.46 N15 1987 12 349.95 N15 1988 01 350.83 N15 1988 02 351.93 N15 1988 03 353.15 N15 1988 04 354.27 N15 1988 05 355.16 N15 1988 06 354.41 N15 1988 07 351.84 N15 1988 08 349.43 N15 1988 09 348.43 N15 1988 10 348.91 N15 1988 11 350.49 N15 1988 12 351.74 N15 1989 01 352.25 N15 1989 02 353.17 N15 1989 03 354.48 N15 1989 04 355.58 N15 1989 05 356.57 N15 1989 06 356.38 N15 1989 07 354.26 N15 1989 08 351.82 N15 1989 09 350.52 N15 1989 10 350.64 N15 1989 11 352.05 N15 1989 12 353.52 N15 1990 01 354.38 N15 1990 02 355.39 N15 1990 03 356.43 N15 1990 04 357.26 N15 1990 05 357.91 N15 1990 06 357.17 N15 1990 07 354.80 N15 1990 08 352.65 N15 1990 09 351.82 N15 1990 10 352.34 N15 1990 11 353.91 N15 1990 12 355.18 N15 1991 01 355.79 N15 1991 02 356.86 N15 1991 03 358.21 N15 1991 04 359.14 N15 1991 05 359.71 N15 1991 06 358.95 N15 1991 07 356.26 N15 1991 08 353.43 N15 1991 09 352.05 N15 1991 10 352.40 N15 1991 11 354.22 N15 1991 12 356.08 N15 1992 01 357.18 N15 1992 02 358.19 N15 1992 03 359.11 N15 1992 04 359.75 N15 1992 05 360.14 N15 1992 06 359.13 N15 1992 07 356.53 N15 1992 08 354.21 N15 1992 09 353.29 N15 1992 10 353.83 N15 1992 11 355.46 N15 1992 12 356.78 N15 1993 01 357.38 N15 1993 02 358.34 N15 1993 03 359.52 N15 1993 04 360.25 N15 1993 05 360.71 N15 1993 06 360.00 N15 1993 07 357.59 N15 1993 08 355.17 N15 1993 09 354.14 N15 1993 10 354.61 N15 1993 11 356.25 N15 1993 12 357.77 N15 1994 01 358.60 N15 1994 02 359.64 N15 1994 03 360.80 N15 1994 04 -999.99 N15 1994 05 -999.99 N15 1994 06 -999.99 N15 1994 07 -999.99 N15 1994 08 -999.99 N15 1994 09 -999.99 N15 1994 10 -999.99 N15 1994 11 -999.99 N15 1994 12 -999.99 N15 1995 01 360.63 N15 1995 02 361.48 N15 1995 03 362.54 N15 1995 04 363.24 N15 1995 05 363.70 N15 1995 06 363.01 N15 1995 07 360.59 N15 1995 08 358.16 N15 1995 09 357.16 N15 1995 10 357.69 N15 1995 11 359.42 N15 1995 12 361.01 N15 1996 01 361.79 N15 1996 02 362.71 N15 1996 03 363.76 N15 1996 04 364.70 N15 1996 05 365.50 N15 1996 06 364.79 N15 1996 07 362.30 N15 1996 08 360.00 N15 1996 09 359.09 N15 1996 10 359.69 N15 1996 11 361.45 N15 1996 12 362.94 N15 1997 01 363.70 N15 1997 02 364.77 N15 1997 03 365.93 N15 1997 04 366.50 N15 1997 05 366.62 N15 1997 06 365.48 N15 1997 07 362.63 N15 1997 08 359.97 N15 1997 09 359.06 N15 1997 10 360.04 N15 1997 11 -999.99 N15 1997 12 -999.99 N15 1998 01 -999.99 N15 1998 02 -999.99 N15 1998 03 -999.99 N15 1998 04 369.68 N15 1998 05 369.97 N15 1998 06 368.94 N15 1998 07 366.50 N15 1998 08 364.48 N15 1998 09 363.92 N15 1998 10 364.78 N15 1998 11 366.62 N15 1998 12 368.08 N15 1999 01 368.78 N15 1999 02 369.84 N15 1999 03 371.09 N15 1999 04 371.85 N15 1999 05 372.18 N15 1999 06 371.19 N15 1999 07 368.35 N15 1999 08 365.53 N15 1999 09 364.32 N15 1999 10 364.93 N15 1999 11 367.00 N15 1999 12 369.03 N15 2000 01 370.19 N15 2000 02 371.16 N15 2000 03 372.02 N15 2000 04 372.58 N15 2000 05 372.84 N15 2000 06 371.66 N15 2000 07 368.92 N15 2000 08 -999.99 N15 2000 09 -999.99 N15 2000 10 -999.99 N15 2000 11 -999.99 N15 2000 12 -999.99 N15 2001 01 -999.99 N15 2001 02 -999.99 N15 2001 03 -999.99 N15 2001 04 -999.99 N15 2001 05 -999.99 N15 2001 06 -999.99 N15 2001 07 -999.99 N15 2001 08 -999.99 N15 2001 09 -999.99 N15 2001 10 -999.99 N15 2001 11 -999.99 N15 2001 12 -999.99 N15 2002 01 -999.99 N15 2002 02 -999.99 N15 2002 03 -999.99 N15 2002 04 -999.99 N15 2002 05 -999.99 N15 2002 06 -999.99 N15 2002 07 -999.99 N15 2002 08 370.41 N15 2002 09 369.90 N15 2002 10 370.87 N15 2002 11 372.83 N15 2002 12 374.35
