It is used for decoding, displaying, and analyzing data, and was originally developed for the National Weather Service (NWS) by Raytheon. There is a division here at UCAR called the NSF Unidata Program Center (UPC) which develops and supports a modified non-operational version of AWIPS for use in research and education by UCAR member institutions . This is released as open source software, free to download and use by anyone. AWIPS takes a unified approach to data ingest, where most data ingested into the system comes through the LDM client pulling data feeds from the NSF Unidata IDD *. Various raw data and product files (netCDF, grib, BUFR, ASCII text, gini, AREA) are decoded and stored as HDF5 files and Postgres metadata by EDEX , which serves products and data over http. *Note : Access to Unidata's IDD data feed is accessible by the University community but is not available to the public freely. We support two data visualization frameworks: CAVE (an Eclipse-built Java application which runs on Linux, Mac, and Windows), and python-awips (a python package). Note : Our version of CAVE is a non-operational version. It does not support some features of NWS AWIPS. Warnings and alerts cannot be issued from our builds of CAVE. Additional functionality may not be available as well.

NSF Unidata AWIPS license information can be found here . AWIPS Data in the Cloud \uf0c1 NSF Unidata and XSEDE Jetstream have partnered to offer an EDEX data server in the cloud, open to the community. Select the server in the Connectivity Preferences dialog, or enter edex-cloud.unidata.ucar.edu (without http:// before, or :9581/services after). Distributed Computing \uf0c1 AWIPS makes use of service-oriented architecture to request, process, and serve real-time meteorological data. Because AWIPS was originally developed for use on internal NWS forecast office networks, where operational installations of AWIPS can consist of a dozen servers or more, we have modified the package to be more applicable in the University setting. Our releases of AWIPS are stripped of operation-specific configurations and plugins. Originally, our EDEX installations were released specifically for standalone installation. This made sense given that a single EDEX instance with a Solid State Drive (SSD) could handle most of the entire NOAAport data volume. However, with GOES-R(16) now online, and more gridded forecast models being created at finer temporal and spatial resolutions, there was a need to distribute EDEX data decoding in order to handle this firehose of data.

Qpid sends alerts to EDEX when data stored by the LDM is ready for processing. These Qpid messages include file header information which allows EDEX to determine the appropriate data decoder to use. The default ingest server (simply named ingest) handles all data ingest other than grib messages, which are processed by a separate ingestGrib server. After decoding, EDEX writes metadata to the database via Postgres and saves the processed data in HDF5 via PyPIES. A third EDEX server, request, feeds requested data to CAVE clients. EDEX ingest and request servers are started and stopped with the commands edex start and edex stop , which runs the system script /etc/rc.d/init.d/edex_camel Read More: How to Install EDEX CAVE \uf0c1 Common AWIPS
