Greetings,

You have reached the directory containing the latest information pertaining to
the comprehensive modelling (CM) effort at GSFC and DSRI.  Brief descriptions
of the files in this directory are as follows:

1) cm3_gji.pdf - PDF file of paper "A comprehensive model of the quiet-time,
                 near-Earth magnetic field:  phase 3", Sabaka, T.J., Olsen, N.
                 and R.A. Langel, Geophys. J. Int., 151, 32-68, 2002.  This
                 paper describes the CM3 model.

2) cm4_gji.pdf - PDF file of paper "Extending comprehensive models of the
                 Earth's magnetic field with Oersted and CHAMP data", Sabaka,
                 T.J., Olsen, N. and M.E. Purucker, Geophys. J. Int., doi:
                 10.1111/j.1365-246X.2004.02421.x (Online Early).  This paper
                 describes the CM4 model.

3) cm4field.f.gz - The CM4 Fortran forward code.

4) interactive_cm4.f - Interactive Fortran forward code which invokes
                       cm4field.f using input from user-prompts.

5) umdl.CM4.gz - Contains the gzipped CM4 model information read by cm4field.f.

6) cm4_example_[1-5].f - Five example Fortran codes illustrating the use of
                         the CM4 forward code.

7) Dst_all.wdc - Contains hourly-means of the Dst index from 1 January 1957
                 to 30 September 2002.  Provisional Dst is listed for years
                 during and after 2001.  These are in WDC format.  See
                 ftp://ftp.ngdc.noaa.gov/STP/GEOMAGNETIC_DATA/INDICES/DST/

8) F107_3mon.plt - Contains 3-monthly-means of absolute F10.7 solar radio
                   flux values from February 1947 to September 2002.  These
                   are in PLOT format.  See
                   ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/SOLAR_RADIO/FLUX/

9) F107_mon.plt - Contains monthly-means of absolute F10.7 solar radio
                  flux values from February 1947 to October 2002.  These
                  are in PLOT format.  See
                  ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/SOLAR_RADIO/FLUX/
