# # ************ USE OF ESRL GMD 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. NOAA relies on the ethics and integrity of the user to # insure that ESRL receives fair credit for their work. If the data # are obtained for potential use in a publication or presentation, # ESRL should be informed at the outset of the nature of this work. # If the ESRL data are essential to the work, or if an important # result or conclusion depends on the ESRL data, co-authorship # may be appropriate. This should be discussed at an early stage in # the work. Manuscripts using the ESRL data should be sent to ESRL # for review before they are submitted for publication so we can # insure that the quality and limitations of the data are accurately # represented. # # Every effort is made to produce the most accurate and precise # measurements possible. However, we reserve the right to make # corrections to the data based on recalibration of standard gases # or for other reasons deemed scientifically justified. # # We are not responsible for results and conclusions based on use # of these data without regard to this warning. # # File Creation: 2016-02-05 00:27:47 # # Project: # # NOAA GMD Data Extension Procedure # # Contact: # # Kenneth Masarie # tel: (303) 497-6270 # email: Kenneth.Masarie@noaa.gov (GMD) # # ************ 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 ESRL 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. # # ************************************************** # # File Content: # # This Data Extension configuration file includes a list of site records # that will be extended using the Data Extension methodology described by # Masarie and Tans, 1995 (JGR). The sites listed here are for a typical # Data Extension run using carbon dioxide measurements from the NOAA GMD # Greenhouse Gas Reference Network (Cooperative Global Air Sampling Network). # This file is used in the computation of the NOAA GMD CO2 global means as # described at www.esrl.noaa.gov/gmd/ccgg/about/global_means.html. # # The file contains 7 columns. # # COLUMN 1 (site): Sampling site identification. The first 3 characters # identify the sampling location. Site codes are defined # at www.esrl.noaa.gov/gmd/dv/site/site_table2.html. # The encoded information following the 3-character site # code is described at # www.esrl.noaa.gov/gmd/ccgg/globalview/gv_filenames.html. # # Columns 2-6 describe parameters used in the curve fitting methods described # by Thoning et al., 1989 (JGR). # # COLUMN 2 (poly): Number of polynomial parameters used in the curve fit # to the data. # # COLUMN 3 (harm): Number of harmonic parameters used in the curve fit # to the data. # # COLUMN 4 (int): Average sampling frequency (in days). # # # COLUMN 5 (short): Low-pass filter parameter (in days) used to characterize # interannual variability in the seasonal cycle. A value # of 80 days corresponds to a full width at half maximum # (FWHM) of approximately 40 days. # # COLUMN 6 (long): Low-pass filter parameter (in days) used to characterize # interannual variability in the long-term trend. A value # of 667 days corresponds to a full width at half maximum # (FWHM) of approximately 365 days. # # COLUMN 7 (mbl): A one (1) in this column indicates that samples from # the site are predominantly of well-mixed marine boundary # layer (MBL) air representative of a large volume of the # atmosphere. Only data from MBL sites are used to construct # global means. # # ************************************************** # site poly harm int short long mbl abp_01D0 3 4 7 80 667 1 alt_01D0 3 4 7 80 667 1 ams_01D0 3 4 7 80 667 1 asc_01D0 3 4 7 80 667 1 avi_01D0 3 4 7 80 667 1 azr_01D0 3 4 7 80 667 1 bme_01D0 3 4 7 80 667 1 bmw_01D0 3 4 7 80 667 1 brw_01D0 3 4 7 80 667 1 cba_01D0 3 4 7 80 667 1 cgo_01D0 3 4 7 80 667 1 chr_01D0 3 4 7 80 667 1 crz_01D0 3 4 7 80 667 1 gmi_01D0 3 4 7 80 667 1 hba_01D0 3 4 7 80 667 1 ice_01D0 3 4 7 80 667 1 key_01D0 3 4 7 80 667 1 kum_01D0 3 4 7 80 667 1 mbc_01D0 3 4 7 80 667 1 mhd_01D0 3 4 7 80 667 1 mid_01D0 3 4 7 80 667 1 pocs35_01D1 3 2 10 200 667 1 pocs30_01D1 3 2 10 200 667 1 pocs25_01D1 3 2 10 200 667 1 pocs20_01D1 3 2 10 200 667 1 pocs15_01D1 3 2 10 200 667 1 pocs10_01D1 3 2 10 200 667 1 pocs05_01D1 3 2 10 200 667 1 poc000_01D1 3 2 10 200 667 1 pocn05_01D1 3 2 10 200 667 1 pocn10_01D1 3 2 10 200 667 1 pocn15_01D1 3 2 10 200 667 1 pocn20_01D1 3 2 10 200 667 1 pocn25_01D1 3 2 10 200 667 1 pocn30_01D1 3 2 10 200 667 1 psa_01D0 3 4 7 80 667 1 rpb_01D0 3 4 7 80 667 1 shm_01D0 3 4 7 80 667 1 smo_01D0 3 4 7 80 667 1 spo_01D0 3 4 7 80 667 1 stm_01D0 3 4 7 80 667 1 syo_01D0 3 4 7 80 667 1 zep_01D0 3 4 7 80 667 1
