Hi Eric, Natalya, Glenn:

1) The standard netcdf java package is at

  http://www.unidata.ucar.edu/packages/netcdf/java/index.html


2) A new, hopefully simpler API is at:

  http://www.unidata.ucar.edu/staff/caron/ma2/ma2.htm
 
this one is pretty new, so may have more bugs. I would reccomend using
it anyway unless you already are familiar with the older API, or like it
better for some reason. However, I wrote the new one, so consider my
bias.


3) udunits package for unit conversion is at:

   ftp://ftp.unidata.ucar.edu/put/netcdf/units_src.jar 


4) we are planning on working on netcdf-through-DODS soon (this month),
but cant promise we'll have anything in time for your semester
deadlines.  However, keep me posted on what you need/have done and i'll
do the same. If you dont need anything before november, its possible i
could help.
