                     ***   FluxNet REVISION HISTORY  ***
                     ***********************************

Version 4.0, 1 October 2001:
  Significant changes:
  - Changed profile input from pressure (mb) to sigma levels
  - Replaced the input cloud pressure variable with cloud temperature
  - Added 200+ cold and high elevation profiles from the Arctic and
    Antarctic
  - Based the network on Streamer v3.0

  Minor changes:
  - Changed the range of cloud particle effective radius for both liquid
    (lower maximum) and ice (lower minimum) clouds
  - Constrained water clouds such that they cannot exist in profiles with
    maximum temperatures less than 253 K.  Previously water clouds could
    have temperatures lower than 253 K but wouldn't if a profile had one or 
    more temperatures above 253.

Version 3.1, 1 June 2001:
  - Changed input profile levels from pressure to sigma levels, so input 
    files that use profiles are not compatible with previous versions.
  - Retrained the network with Streamer v3.0
  - Added a normal random number generator for better sampling of some 
    variables in training.
  - Added another sample application.

Version 3.0a, 7 Feb 2000:
  - Added an initialization of 'j' in snns/mkdat*.c programs.  This could 
    be a small problem on some systems, but will NOT affect FluxNet itself.
    It's only an issue in sampling for training data.  (No new version number)

Version 3.0, 15 July 1999:
  - Added TOA fluxes to output; added specification of surface type to input
  - Fixed bug in cloud water content
  - Expanded the range of cloud droplet size and ice cloud temperature
  - Increased the percentage of clear and completely overcast cases
  - Set cloud properties to fixed values in clear cases
  - Added an HTML version of the user's guide.

Version 2.1.1, 5 Apr 1999:
  - Modified manual to reflect "bug" in specification of cloud water content.
    Important!  (No change to code.)

Version 2.1, 9 Sep 1997:
  - Retrained with greater number of dark and clear sky cases
  - streamlined 'run.f'.

Version 2.01, 22 May 1997:
  - Fixed bug concerning incorrect cloud top temperature in Streamer run.

Version 2.0, 20 Apr 1997:
  - One network outputs shorwave and longwave fluxes
  - Redesigned network for use with global TOVS profiles
  - Simplified steps for redesign and implementation

Version 1.0, 28 Aug 1996:
  - Version 1.0 release. Expanded the albedo range for snow revised the 
    documentation.

Version 1.0B, 16 Jul 1996:
  - First Beta test release.
