There are two reasons for my reply: 1) the way that dates are stored in McIDAS area files is, in fact, a problem for the _long_ haul. Dates are stored as seconds since 1970, so they will stop being unique after sometime in the year 2032. The good news for both of us is that we shouldn't have to worry about this :-) 2) at one point you were thinking of ingesting the NIMAGE (NOAAPORT GINI images) feed on a machine at COD. What is your current thinking on this? I ask because I see that COD machines are still the greatest users of GINI imagery on the cooperating community ADDE server, adde.ucar.edu: 18.104.22.168 8.05D+09 climate.cod.edu 22.214.171.124 2.22D+09 dyn253-03.cod.edu These numbers are bytes accessed since the last time the log file was rotated, which was last Friday night. Continued ADDE access to the images on adde.ucar.edu is not a problem, but it would be more efficient if you were ingesting and accessing them locally. Also, as we talked about before, if you were ingesting the data, you could turn around and offer access to it to other sites through ADDE server(s) on your own machine.
