After long last, v6.0 is official! Onward to v6.1!

Only a few changes were made from RC2. The brief Release Notes follow:

An updated tar file of v6.0 with the accumulated changes over the past year or so has been posted on the web site Software page. Following are the Release Notes with a short description of the significant changes for the updated version. Instead of using version numbers, we will refer to this updated version by the date (July 2008).

- All references to "interface.h" have been removed from the code. This was for compatibility with the old DEC Fortran compiler for Windows in mixing Fortran and C calls. The newer Intel Windows compilers use the same technique as the CRAY compilers (see utils_sub_names.h).

- Various bug fixes to the observational nudging FDDA schemes were made.

- Microphysics bug fix in the collection routines.

- The topography initialization (when creating the topo surface file) now uses a linear interpolation rather than the overlapping polynomial method. This eliminates the fictitious negative topo values seen along some coastlines and still allows sub-sea level topography when it should occur.

- Bug fix in horizontal diffusion that caused mass non-conservation. Affected primarily scalar quantities. (Found by :

Mass conservation above slopes in the Regional
Atmospheric Modelling System (RAMS)
Environ Fluid Mech (2008) 8:239–248)

- Several additions to utils 2.4 for future capabilities.

- NCSA made a change in the naming of some HDF5 routines. The utils 2.4 code in the tar files is configured for HDF5 1.8.0 or higher. So either move up to this version, use an older utils 2.4 version, or:

- Edit utils/2.4/lib/hdf5_f2c.c
- Change references to "HDFopen1" to "HDFopen" and "HDFCreate1" to "HDFCreate" (simply remove the 1)

- If it hasn't been mentioned in the past, the Lambert-Conformal projection seems to be working well. But as with all newer things, check the results carefully. WARNING: most of the post-processing applications (e.g., REVU, HYPACT) have not yet been updated to handle the LC runs. Newer versions of these will be coming soon.

- The old iralloc and irfree routines have been removed from utils 2.4.
