These files contain ozone profile data from the SBUV (Solar Backscatter Ultraviolet) instrument
onboard the Nimbus 7 spacecraft. Data covering the entire Nimbus 7 SBUV lifetime, November
1, 1978 through June 21, 1990, are given as daily files of individual measurements, and as zonal
means. All data are in ASCII format so they can be read on any platform. This is version 6 data -
it has been corrected for calibration drift and should give accurate trends. (A version 7 processing
will not be available for a year or more.)
IMPORTANT NOTE: the data after February 13, 1987 were affected by a chopper synchronization error. A correction has been applied and there is no apparent bias in this data, but the uncertainty of individual profiles is much higher!
