Originally data was recorded on magnetic tape. The old tapes became unreliable
and data was copied to optical discs in 1990. The optical disc media in turn
became expensive and unreliable to support.
In 1997 a NERC SEEDCORN grant was awarded
to move the data to CD-ROMs which could make the data available on a wide
variety of hardware. This opportunity was also used to catalogue and
publicise the archive.
This archive is intended as a supplement to that at the British Atmospheric Data Centre which concentrates on retrieved geophysical parameters (Temperatures, volume mixing ratios etc) rather than the radiance data available here. Low level radiance data is less in demand not least because its interpretation requires more knowledge of the details of the instrument making the measurements.
