Unidata is a national program to help universities acquire
weather data and to analyze and display those data for
teaching and research. The program is funded by the National
Science Foundation and managed by the University Corporation
for Atmospheric Research. Unidata negotiates a group con-
tract with a commercial data-broadcasting firm so that
universities may receive weather data at a discount. Uni-
data develops and distributes software for capturing,
analyzing, and displaying those data locally. Unidata also
advocates on behalf of universities on data issues in
Federal and other arenas.
Unidata-developed software includes the Unidata Local Data
Manager (LDM), which captures real-time weather data from a
satellite broadcast, and netCDF, a network-transparent,
self-describing form for storing scientific data. The LDM
is being enhanced to allow users to capture and forward data
over the Internet.
Unidata distributes applications software developed and
licensed by universities. These are Purdue University's
Weather Processor (WXP) and the University of Wisconsin's
McIDAS-OS2 and McIDAS-X software. WXP and McIDAS-X are
UNIX-based applications; McIDAS-OS2 runs on PS/2 computers
with the OS/2 operating system. Unidata also distributes and
supports the UNIX version of NASA's GEMPAK (for General

Meteorological Package) and a UNIX-based, general-purpose
data-analysis and image-processing research package called
YNOT, developed by MacDonald Dettwiler under a Unidata con-
tract.
Unidata provides bug fixes, upgrades, and software distribu-
tions over the Internet. Software support includes forming
and maintaining special-interest mailing lists, offering
advice on hardware acquisitions, and holding semiannual
training workshops in the use of Unidata-supported software.
Consultation with users is conducted via email. The program
also publishes a quarterly newsletter.

Unidata is connected via a LAN to NCAR, an NSFNET backbone
site. All software is distributed via ftp. The Unidata
NetCDF software is freely available; you can access a
compressed tar file ("cd incnetcdf.tar.Z" in directory
"pub") via anonymous ftp from "unidata.ucar.edu".
