The Data Usage Guide is a flowchart designed to illustrate: 1) the type of data access methods available; and 2) the display capabilities of the Unidata visualization packages for each available data type.
A data fact sheet is available to provide a brief overview of data available from Unidata.
Questions or comments about data usage and guidelines can be sent to: support@unidata.ucar.edu
Unidata provides topical mailing lists to enable Unidata users to exchange information freely on topics of mutual interest. Listed below are data-related mailing lists of general interest for discussing the various data available, contents of our data streams, etc.
NOTE: Anyone posting to a list in an attempt to advertise or sell goods/services will be immediately unsubscribed and banned from the list.
List Name | List Description |
bufrtables @unidata.ucar.edu ![]() |
An informal technical working group for developers of software that read and write WMO BUFR messages. We have a need to share standardized, machine-readable BUFR tables, if BUFR is to be used across institutions or to archive data. |
cf-satellite @unidata.ucar.edu ![]() |
A mailing list for the discussion to propose a CF Convention for satellite data. |
conduit @unidata.ucar.edu ![]() |
Working collaboratively with NOAA's National Weather Service (NWS), National Centers for Environmental Prediction (NCEP), NASA's Goddard Space Flight Center (in the early years), and the Unidata Program Center (UPC), and with cooperation from the university community, Unidata's Internet Data Distribution (IDD) has been used for distribution of CONDUIT high resolution model data sets. The data consist of a substantial set of the data made available on servers at the NCEP and at NWS. |
decoders @unidata.ucar.edu ![]() |
This mailing list is for announcements and discussion of the Unidata decoders package, for converting various kinds of meteorological bulletins into netCDF data. In addition to the GRIB decoder (gribtonc) written in C, the package includes four perl decoders: a synoptic decoder (syn2nc ), a buoy decoder (buoy2nc ), a METAR decoder (metar2nc ), and an upper-air decoder (ua2nc ). |
galeon @unidata.ucar.edu ![]() |
GALEON is an informal interoperability experiment Unidata is initiating with a number of members of the Open Geospatial Consortium (OGC) to determine the feasiblity of using the Web Coverage Service (WCS) interface specification to access netCDF datasets. The goal is to determine whether extensions to the WCS specification are needed in order to facilitate access to netCDF datasets commonly used in atmospheric and ocean sciences communities. |
gifsfg @unidata.ucar.edu ![]() |
The THORPEX Global Interactive Forecast System (GIFS) Focus Groups mailing list. The THORPEX implementation plan envisages the establishment of a future Global Interactive Forecast System (GIFS), to realise benefits of the THORPEX research programme by developing improvements to operational forecasting systems. To develop detailed technical solutions in support of the GIFS, and for the implementation of its various phases (e.g., generation of different products, such as TC, PQPF), focus groups have been created to investigate access to and distribution of real time and archived ensemble data, and to develop ensemble based products and services for high impact events. The THORPEX GIFS mailing list has been created to facilitate discussion and provide announcements regarding GIFS development across the focus groups and interested parties. |
idd-brasil @unidata.ucar.edu ![]() |
The idd-brasil email list is akin to the ldm-users email list. It was created for South American IDD participants so they could correspond with each other about IDD related issues in their native languages which are either Portugese or Spanish. |
ldm-users @unidata.ucar.edu ![]() |
This is an unmoderated list for announcements, discussions, bug reports, and questions about the LDM software and Unidata's Internet Data Distribution (IDD) system. It is also the main list for general data requests when data have been missed (other users will help replace the missing data). Typical postings include discussions on using the LDM; discussions of issues related to porting to various platforms; information about changes to stations; and discussion of issues and priorities affecting the further development of the LDM and the IDD. |
needdata @unidata.ucar.edu ![]() |
This list is used to request missing or retrospective data. In the spirit of community that has made Unidata a success, subscribers help each other by supplying data that they have available (note that you must be subscribed to the list to post a request). Please be reasonable in your requests; don't expect someone to dig out six months of radiosonde data from 20 years ago. |
noaaport @unidata.ucar.edu ![]() |
This mailing list provides an opportunity for users to exchange information regarding the installation and operation of a local NOAAPORT receiver and data ingestion site. Unidata makes its locally developed downlink and LDM-ingestion software freely available as unsupported software, along with information regarding specific hardware in use. |
nws-changes @unidata.ucar.edu ![]() |
The nws-changes mail list contains announcements from the National Weather Service (NWS) about changes to NWS data streams. The announcements relate to formats and content and first appear in administrative messages in the data streams being modified. NWS also provides the information directly to Unidata so that we can broadcast the notices and examples over the nws-changes mail list. |
suominet @unidata.ucar.edu ![]() |
This mailing list consists of individuals participating, or interested in, the SuomiNet project. |
tiggelam @unidata.ucar.edu ![]() |
The TIGGE Limited Area Model (LAM) Project mailing list. Recently, a TIGGE-LAM Panel of Experts was established to support the development of the Limited Area Model Ensemble Prediction System component of TIGGE. This Panel should work in close coordination with the GIFS-TIGGE WG, in liaison with already existing LAM EPS initiatives and in coordination with the THORPEX regional committees. The TIGGE-LAM mailing list has been established to facilitate discussion and provide announcements regarding TIGGE-LAM development across the panel and interested parties. |
tiggeusers @unidata.ucar.edu ![]() |
The TIGGE User's Group (TUG) mailing list has been created as an open platform for users to exchange information and ideas to one another regarding the TIGGE project. Messages informing users of newly released features available on the NCAR TIGGE web portal will be presented through this mailing list. |
