= Release notes for PDAF = == Version 1.7 - September 16, 2011 == Changes:[[BR]] * Revised internal structure of PDAF for simplified implementation of additional assimialtion methods * Added full data assimialtion implementation of Lorenz-96 model with PDAF. * Revision of observation localization. It also includes the regulated localization that was introduced in the paper "A regulated localization scheme for ensemble-based Kalman filters" by L. Nerger et al. to appear in Q. J. Roy. Meteor. Soc." * Added on option to display parameter options for a selected filter. * License change: Now PDAF is licensed with the more flexible Lesser GNU Public License (older versions of PDAF used the GNU Public License). ---- == Previous versions == === Version 1.6.2 - 10/05/2010 === Changes:[[BR]] * Change in Makefiles to correct compilation on Linux with gfortran === Version 1.6.1 - 08/27/2010 === Changes:[[BR]] * Added pre-processor statement PDAF_NO_UPDATE to simplify tests during implementation. * Unified interface to pre/poststep routines.
