Howdy Jen and Matt! Thanks for pointing out the problem with the netCDF 3.6.1 Irix binary. Problem was that there is no compress utility on our Irix64 machine. So I've gotten a gzipped version of the 3.6.1 binaries for Irix. Take a look here: http://www.unidata.ucar.edu/software/netcdf/binaries.html Thanks again!
