Subject: [OpenMadrigal-users] U. Mass Lowell Digisonde data
Message-ID: <200205091930.PAA16802@chaos.haystack.mit.edu>

The U. Mass Lowell Digisonde data has been stored in an experiment
directory called /opt/madrigal/experiments/1976/mlh/03dec76. There was
also a Millstone ISR experiment called
/opt/madrigal/experiments/1976/mlh/03dec76h.  Thus, while the digisonde
did have a unique instrument code (2550), its mnemonic collided with the
Millstone ISR mnemonic. Bill Rideout has now moved the digisonde data to
/opt/madrigal/experiments/1976/uld/03dec76 and the ISR data to
/opt/madrigal/experiments/1976/mlh/03dec76. Some programs, particularly
those related to calibration of the ISR data may need to be changed.

Subject: [OpenMadrigal-users] DST index
Message-ID: <200205151552.LAA11822@chaos.haystack.mit.edu>

Glenn Campbell has downloaded the DST index, covering 1957-2001, from
NCAR and I have converted the file to Madrigal format and installed it
in the Madrigal Database at Millstone.

Subject: [OpenMadrigal-users] Additions to Haystack Openmadrigal site
Message-ID: <200205171617.MAA17642@chaos.haystack.mit.edu>

All Millstone Hill I.S. Radar default data files at the Haystack
Openmadrigal site now have catalog and header records at the beginning
of the file. The velocity data in these files is now chirp-corrected.
Local users who directly access the database through Fortran programs
should no longer ask the Fortran library to do this correction.

Several new Geopysical index files have been added to the database
including IMF and Plasma data, Estimated Hemispheric power, Midnight
Equatorward Boundry, Sunspot Number, AE and Dst. Time-coverage varies.
These files were imported from the NCAR CEDAR Database and installed as
is.  They will eventually be reorganized to reduce access time to
individual records.
