During 1982, the NHC started to include data on Central Pacific tropical storms and hurricanes within the database, before they took over the responsibility for issuing advisories during 1988.
The format of the Eastern Pacific database was subsequently significantly changed during 2013 to include non-synoptic best track times and non-developing tropical depressions.
[5] Over the next couple of decades, it became obvious that the database needed to be revised because it was incomplete, contained significant errors, or did not reflect the latest scientific understanding regarding the interpretation of past data.
[6] Charles J Neumann subsequently documented several of these problems and obtained a grant, to start addressing them in a programme that was eventually called the Atlantic Hurricane Database Re-analysis Project.
[9][10][11] In 2013, the archive's format was significantly changed to include non-synoptic best track times, non-developing tropical depressions and wind radii.
