2.4.0 - 2017-02-14

  • Delete unnecessary scenarios and add documentation for remaining ones (Matt West).

  • Allow selection of weighting function in spec file (Jeff Curtis).

  • Entropy calculation helper functions added (Nicole Riemer).

  • Add chamber models for wall and settling losses (Jian Tian).

  • Add fractal particle model treatment, following Naumann [2003] (Jian Tian).

  • Composition sampling uses a new mean-projection algorithm to give better spread (Matt West).

  • Clean up browian coagulation function (Jeff Curtis).

  • Convert code internals to use allocatable arrays rather than pointers (Jeff Curtis).

2.3.0 - 2015-03-29

  • Pressure is now specified as a profile rather than a constant value.

  • Add variable-composition aerosol distributions with a mean and standard deviation per species.

  • Each particle source is now resolved with equal number of computational particles.

  • Output NetCDF files now store per-particle number concentration in aero_num_conc, which is the inverse of the previous aero_comp_vol variable.

  • Fix accelerated coagulation for negative weightings to only activate for small/large events.

  • Fix allow_doubling/allow_halving with weighted particles.

  • Replace Bessel function code with an LGPL-licensed version.

  • Distributed parallel coagulation is disabled due to lack of weighting support.

2.2.1 - 2012-03-30
