Dear Rick,

Thanks for the response. Let me figure out how to use the ftp.

I note that it is not the same file as the single file instance that you cited, and I *think* NCL would have ingested all the files from 1901 up to the 199501 before throwing the error. Are you able to open the file with the ncl_filedump command, or any of the NCO/CDO operators?  If you want to send it to our ftp site, I'll take a look at it (instructions below).
