 VERSION           CHANGE

1.0 2007-2-14  - initial release (beta version)
1.1 2007-3-2   - more instructions and documents (e.g., README files 
                 in each sub-directory) have been added.
1.2 2007-5-1   - The routine name "vis_IR" has been changed to "SIMvisir"
                 to be parallel with the other simulator units.
               - variable name "lne" changed to "lge" in radar/radar-echo.f.
               - A misplaced comment was corrected in radar/SIMradar.f.
               - "ISPC" is explicitly defined where "GETPH3B" first appears
                 in vis_IR/SIMvisir.f. This is necessary for some compilers.
               - "GRIDparameters.inc" has been included in microw/linpak.f
                 to replace the internally defined "mxlyr".
               - A misspelled variable name in vis_IR/SIMvisir.f was 
                 corrected (GLAB->GALB).
1.3 2007-8-24  - A correction was made so that the freezing particle modeling 
                 is excuted only when nzfrz > 1 in radar/SIMradar.f.
               - Comments have been added in "src/MieLUT/maketab.f" etc so
                 that users make sure that the LUT name should be properly 
                 specified when the channel frequecies are changed.
               - Misspelled variable (PNOS->PN0S) was corrected in 
                 vis_IR/SIMvisir.f
               - A bug was fixed in vis_IR/vlspc3.f (a factor of two was
                 multipled to the exponential DSD).
               - GETPH3B has been updated to GETPH3Z in vis_IR/ to take into 
                 account large particles typical of precipitation. 
                 The built-in Mie Kernel is extended to larger size parameters
                 assuming the geopmetrical optical approximation. 
                 vis_IR/SIMvisir.f and makefile were updated correspondingly.
