Nbsp contains two new (Tcl) scripts, nbspgisradmap and nbspgissatmap, that use the NbspGismap library that make it very easy to cerate radar and sat maps using the noaaport data.

On the presentation side, the radar and satellite images, as well as the loops, can now be generated dynamically from the web interface.

Regarding the package, Expect is no longer required so it is not a
pre-requisite (it was needed for tclgrads which is used in the gribfilter).

In terms of peformance, the gempak filter now opens a permanent separate connection to each gempak decoder and the performance is so improved in SMP machines) that the filter can be added to the default configuration without any problem.

The biggest new addition is the clusterfilter for running any of the filters in any of a set of nodes, as if they were local.

• it is a slave off the inoaaport servers to receive only text files
• only those filters that process text files are enabled,
  rstfilter, dafilter, metarfilter and msgfilter;
  the gpfilter can be enabled if desired (requires Gempak)

The second version, nbsp2ldmVA, comes with Ldm configured, and with only the ldmfilter enabled (all the others except the inventory are disabled). Both have the Gempak package installed and configured.

The images and README files can downloaded by anonymous ftp from

• ltp.uprrp.edu

in the directory

• pub/nbspVA

The README’s have the information needed to start the machines, in particular the login credentials, and how the installed packages nbsp, npemwin, gempak, ldm are configured.
