Re: Display of netCDF data with other mechanisms
I sent this once but must have gone to Dan...so here goes
With regard to Dan Kelley's comment about a lack of information
regarding netCDF. There are two pieces of information that
some of you may want to know (if you don't already):
1) You can display information in netCDF *.nc files with Mosaic;
2) You can display netCDF data with Zeb.
1) Mosaic is a browser that lets the user explore machines running ftp
and http servers on the world wide web. For more information
contact http://www.ncsa.uiuc.edu/. A sample output is:

2) I found a reference to Zeb in an AMS paper. Here is the beginning of
the overview from the http://www.atd.ucar.edu/ Home Page.
Zeb(1) is a data integration, analysis, and display system designed for
the needs of atmospheric scientists in a number of contexts. Zeb provides
a number of features, including:
Inclusion of a wide variety of datasets. Data can be brought into the system
from a number of sources, including doppler radar, surface stations,
radiosondes, aircraft, satellite, and numerous others.
Integration of these datasets at display time. Any number of overlays from
different data sources may be placed on the same window simultaneously,
allowing them to be seen in relation to each other.
Advanced graphical displays, including time-based animation (movies) and
vertical cross sections through data.
Friendly user interface. Almost all of the features of zeb are available
using mouse-oriented commands. Most aspects of any plot are easily changeable
by inexperienced users.
Configurability. Zeb may be extensively reconfigured to meet the needs of
different projects, datasets, and users.
Portability. The zeb code was designed to be portable to a wide variety of
platforms.
Application throughout the research cycle. Zeb is intended to be used both in
real time, during data collection, and afterward, during the postprocessing
and analysis stage.
