************ 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. *********************************************************** MHD 1991 06 356.18 MHD 1991 07 351.46 MHD 1991 08 348.22 MHD 1991 09 349.69 MHD 1991 10 353.30 MHD 1991 11 356.56 MHD 1991 12 358.71 MHD 1992 01 359.98 MHD 1992 02 359.90 MHD 1992 03 360.14 MHD 1992 04 361.26 MHD 1992 05 360.34 MHD 1992 06 358.09 MHD 1992 07 352.74 MHD 1992 08 346.65 MHD 1992 09 346.83 MHD 1992 10 353.08 MHD 1992 11 357.11 MHD 1992 12 358.29 MHD 1993 01 359.01 MHD 1993 02 359.60 MHD 1993 03 361.10 MHD 1993 04 362.46 MHD 1993 05 361.33 MHD 1993 06 358.05 MHD 1993 07 353.14 MHD 1993 08 348.49 MHD 1993 09 349.44 MHD 1993 10 353.70 MHD 1993 11 356.89 MHD 1993 12 359.01 MHD 1994 01 360.31 MHD 1994 02 361.16 MHD 1994 03 362.78 MHD 1994 04 363.49 MHD 1994 05 362.26 MHD 1994 06 359.20 MHD 1994 07 354.57 MHD 1994 08 350.19 MHD 1994 09 351.10 MHD 1994 10 355.42 MHD 1994 11 359.35 MHD 1994 12 361.63 MHD 1995 01 363.35 MHD 1995 02 363.87 MHD 1995 03 364.29 MHD 1995 04 365.42 MHD 1995 05 363.95 MHD 1995 06 360.40 MHD 1995 07 356.92 MHD 1995 08 353.84 MHD 1995 09 354.84 MHD 1995 10 357.92 MHD 1995 11 361.88 MHD 1995 12 364.66 MHD 1996 01 365.41 MHD 1996 02 366.78 MHD 1996 03 368.29 MHD 1996 04 367.48 MHD 1996 05 366.27 MHD 1996 06 364.72 MHD 1996 07 359.66 MHD 1996 08 354.76 MHD 1996 09 354.95 MHD 1996 10 358.92 MHD 1996 11 363.48 MHD 1996 12 367.05 MHD 1997 01 367.30 MHD 1997 02 366.52 MHD 1997 03 367.51 MHD 1997 04 367.97 MHD 1997 05 367.84 MHD 1997 06 365.18 MHD 1997 07 358.72 MHD 1997 08 354.50 MHD 1997 09 355.49 MHD 1997 10 361.73 MHD 1997 11 367.72 MHD 1997 12 370.00 MHD 1998 01 370.49 MHD 1998 02 369.02 MHD 1998 03 368.60 MHD 1998 04 370.09 MHD 1998 05 369.20 MHD 1998 06 366.55 MHD 1998 07 361.79 MHD 1998 08 357.96 MHD 1998 09 360.05 MHD 1998 10 365.03 MHD 1998 11 368.23 MHD 1998 12 369.98 MHD 1999 01 370.84 MHD 1999 02 370.94 MHD 1999 03 372.34 MHD 1999 04 374.04 MHD 1999 05 373.29 MHD 1999 06 369.85 MHD 1999 07 364.07 MHD 1999 08 359.83 MHD 1999 09 360.77 MHD 1999 10 366.15 MHD 1999 11 369.79 MHD 1999 12 371.57 MHD 2000 01 372.73 MHD 2000 02 372.74 MHD 2000 03 373.37 MHD 2000 04 374.58 MHD 2000 05 373.80 MHD 2000 06 371.31 MHD 2000 07 366.74 MHD 2000 08 361.24 MHD 2000 09 361.78 MHD 2000 10 366.64 MHD 2000 11 371.48 MHD 2000 12 373.60 MHD 2001 01 373.84 MHD 2001 02 375.08 MHD 2001 03 376.70 MHD 2001 04 376.14 MHD 2001 05 374.72 MHD 2001 06 371.77 MHD 2001 07 366.82 MHD 2001 08 362.04 MHD 2001 09 363.35 MHD 2001 10 368.04 MHD 2001 11 373.70 MHD 2001 12 378.92 MHD 2002 01 377.50 MHD 2002 02 375.74 MHD 2002 03 377.54 MHD 2002 04 377.96 MHD 2002 05 376.91 MHD 2002 06 374.07 MHD 2002 07 368.34 MHD 2002 08 363.53 MHD 2002 09 365.38 MHD 2002 10 370.04 MHD 2002 11 375.51 MHD 2002 12 380.65
