HURSAT-B1 Revision information

Current Version - 3.0
- Released - 1 December 2007
- Features
  - Version 2.0 bugs fixed.
  - New storm name format will not change as data are updated.
  - No storm tracks from JTWC East Pacific are used.
  - Better QC instituted to remove corrupt files.
  - More thorough merging of HURDAT and JTWC storm tracks. Changes to best track files are documented online.
  - Files were made smaller by replacing the VZA array with a scalar value of view zenith angle for each file
- Bugs
  - Storm names from non-HURDAT storms did not make it into the HURSAT-B1 filenames. This has no impact on the data itself, just the filenames.
Version 2.0
- Released - 30 June 2007
- Features
  - Version 1.0 bugs fixed.
  - Storm location, central pressure and maximum sustained wind provided as variables.
  - netCDF metadata provides traceability by providing original JTWC/HURDAT filenames for each netCDF file.
  - Filename changed from hursat-geo to hursat-b1
- Bugs
  - Two storms had inverted temperature scales (1982WP027 and 1982WP028)
  - Some storms were inadvertantly included (sometimes called invests)
  - Incorrect temporal interpolation when original best track data was not 6-hourly
Version 1.0
- Bugs
  - Data not fully CF compliant
  - View zenith angle (VZA) grid calculated incorrectly - although the VZA value in the filename is correct.
  - Some positions were interpolated incorrectly from 6-hourly to 3-hourly (for instance, the last 8 interpolated positions for Ophelia in 2005)
