Introduction
Six files are described below that give additional details
on the data, priors, uncertainties, and pre-subtracted fields
used in the inversion. "2004GB002439-station_list.txt" gives
details of the 78 measurement time series used in the inversion.
while "2004GB002439-data_and_uncert.txt" provides the data
values and data uncertainties assumed for these stations, for
each month in the span. "2004GB002439-presub_FF.txt" and
"2004GB002439-presub_CASATak.txt" give the fossil fuel and
land/ocean flux perturbations, respectively, for each of the
13 transport models, that are subtracted off of the observed
CO2 concentrations before the inversion is performed.
The seasonally-varying a priori fluxes and a priori flux
uncertainties assumed in the inversion are given in
"2004GB002439-prior_fluxes.txt" and
"2004GB002439-prior_errors.txt", respectively.
1. 2004GB002439-station_list.txt Details on the 78
GLOBALVIEW-CO2 (2004) time series used in the inversion.
1.1 Column "#", sequential station number (1-78) out of
the 78 stations used in the inversion.
1.2 Column "GV#", sequential station number (1-203) out of
the 203 stations in the GLOBALVIEW-CO2 (2004) dataset
1.3 Column "GV_name", GLOBALVIEW-CO2 station name
1.4 Column "Lat", degrees, station latitude
1.5 Column "Lon", degrees, station longitude
1.6 Column "Elev", meters, station elevation above sea level
1.7 Column "MBL", (0 or 1), whether station is considered a marine
boundary layer site (=1) or not (=0) by GLOBALVIEW-CO2
1.8 Column "rsd", ppm volume, the 1979-2003 'rsd' value [ppmv] from
the GLOBALVIEW 'wts' file. This is the RMS residual of the actual
observations about the GLOBALVIEW smooth curve; annually-varying
versions of this value across 1988-2003 are used in calculating the
data uncertainties (model-data mismatch errors) used in the inversion
('sigma_ann' in equation (A2) in Appendix A).
1.9 Column "88", (0-48), number of GLOBALVIEW 'weeks' (48/year)
with data available, 1988
1.10 Column "89", (0-48), number of 'weeks' with data available, 1989
1.11 Column "90", (0-48), number of 'weeks' with data available, 1990
1.12 Column "91", (0-48), number of 'weeks' with data available, 1991
1.13 Column "92", (0-48), number of 'weeks' with data available, 1992
1.14 Column "93", (0-48), number of 'weeks' with data available, 1993
1.15 Column "94", (0-48), number of 'weeks' with data available, 1994

1.18 Column "97", (0-48), number of 'weeks' with data available, 1997
1.19 Column "98", (0-48), number of 'weeks' with data available, 1998
1.20 Column "99", (0-48), number of 'weeks' with data available, 1999
1.21 Column "00", (0-48), number of 'weeks' with data available, 2000
1.22 Column "01", (0-48), number of 'weeks' with data available, 2001
1.23 Column "02", (0-48), number of 'weeks' with data available, 2002
1.24 Column "03", (0-48), number of 'weeks' with data available, 2003
1.25 Column "%_Real", %, percentage of GLOBALVIEW 'weeks' with real
(as opposed to interpolated) data available, 1991-2000
2. 2004GB002439-data_and_uncert.txt CO2 concentration observations
and data uncertainties for the 78 stations for each of the months
in the inversion span (192 months, Jan 1988 - Dec 2003).
2.1 Column "#", station number (1-78)
2.2 Column "Mon", month number (1-192) (Jan 1988 - Dec 2003)
2.3 Column "Data", ppm volume, observed CO2 mixing ratio
2.4 Column "Uncert", ppm volume, assumed data uncertainties
(ie., model-data mismatch errors)
3. 2004GB002439-presub_FF.txt The CO2 concentration perturbations
[ppmv] caused by the interannually-varying fossil fuel fluxes, as given
by each of the 13 atmospheric transport models. These time series are
pre-subtracted from the observed CO2 concentrations before the inversion.
Note: an arbitrary offset may be added to the values for each transport
model; this is because the inversion solves an offset to the final
(pre-subtracted) concentrations as part of the inversion process.

4. 2004GB002439-presub_CASATak.txt The CO2 concentration perturbations
[ppmv] caused by the seasonally-varying CASA land biosphere fluxes and
Takahashi (1999) ocean fluxes, as given by each of the 13 atmospheric
transport models. These time series are pre-subtracted from the observed
CO2 concentrations before the inversion.
Note: an arbitrary offset may be added to the values for each transport
model; this is because the inversion solves an offset to the final
(pre-subtracted) concentrations as part of the inversion process.

5. 2004GB002439-prior_fluxes.txt A priori fluxes [PgC/yr] assumed in the
inversion, by region. Note: since the effect of the seasonally-varying
CASA land fluxes and Takahashi ocean fluxes has been pre-subtracted
from the observations, the fluxes estimated (and the a priori fluxes)
are in terms of corrections to these pre-subtracted values
