This is a general readme for the CDAWeb data directories under 
cdaweb.gsfc.nasa.gov/pub/istp:

DATA FILES:
Each yearly or day of year (doy) directory contains data files that, 
in most cases, are CDF files.  CDF stands for Comman Data Format. More
information on this format and software to read/write files in CDF
can be found at http://cdf.gsfc.nasa.gov

METADATA:

Many of these individual data files have incomplete internal
descriptions of the physical meaning of their parameters.  For these
datasets, the better metadata can usually be found in what we call
"master cdfs".  Master cdfs are cdf files that contain just the
metadata attributes for a given dataset and its variables.  All public
CDAWeb master cdfs can be downloaded from the CDAWeb anonymous ftp
site at https://cdaweb.gsfc.nasa.gov/pub/CDAWlib/0MASTERS


PLOT/LIST/SUBSET DATA FILES:

All CDF files can be opened and read with the CDF distribution
software found at at http://cdf.gsfc.nasa.gov.  The content of these
data files joined with the master CDF metadata is best accessed (plot,
list in ASCII, file download of selected variables and times) using
the CDAWeb user interface at http://cdaweb.gsfc.nasa.gov/.  These
functions are also available via a web services API described at
http://cdaweb.gsfc.nasa.gov/WebServices/.


IDL USERS:

IDL users may also find useful the CDAWlib s/w library at
http://spdf.gsfc.nasa.gov/CDAWlib.html and the CDFX display and
listing tool at http://cdaweb.gsfc.nasa.gov/cdaweb/cdfx/

Brief Description: The directory contains the subdirectories containing all
of the PUBLIC space physics data supported by the CDAWeb system. Under each
satellite/source subdirectory will be another set of subdirectories broken
out by dataset from investigations from that satellite/source. Then under
each of these directories there are subdirectores for each year where we
have data files, ie. wind/mfi/1999.
