Recent changes to pregrid programs

This file documents recent changes to the pregrid programs. We'll see if I'm disciplined enough to keep it reasonably up-to-date.

2000-10-27 (pregrid version 0.23):

• Added a program (util/build_mosaic.F) to combine two or more tiles of a lat/lon grid into one tile. See the associated comments in the FAQ file for a few details.
  
  Affected files:
  
  util/build_mosaic.F (new source-code file)
  Makefile (option to make the program by issuing the command "make build_mosaic")
  

2000-09-07 (pregrid version 0.22):

• A SUN portability problem. Subroutine GRIBPRINT wasn't building format strings quite right. That has been corrected.
  
  Affected files:
  
  util/gribcode.F (subroutine gribprint)
  
  
  
• A SUN portability problem. Subroutine GRIBLLG had negative steps in an array reference. That confused SUN and has been replaced by a do-loop.
  
  Affected files:
  
  util/gribcode.F (subroutine griblgg)
  

2000-08-31 (pregrid version 0.21):

• Changed the grib.misc program and the ncep.grib program to recognize the field name "SKINTEMP" in the Vtable as something we can use as a sea-surface temperature.
  
  Affected files:
  
  grib.misc/pregrid_grib.F
  ncep.grib/pregrid_ng.F
  ncep.grib/output.F
  
  
  
• Turned off an error print (actually a warning) that was scaring people in ncep.grib program. This happened when the program, as expected, tried to open a non-existent file.
  
  Affected files:
  
  ncep.grib/rd_grib.F
  util/cio.c
  

2000-08-10 (pregrid version 0.20):

• Added the "thinned-grid" capability to GRIB processing. This code will now be able to deal with the WAFS grids 37 to 44 on an individual basis. There is still no mosaic capability in pregrid.
  
  Affected files:
  
  grib.misc/rd_grib.F
