The NSF Unidata server hosted at the Space Science and Engineering Center (SSEC) at the University of Wisconsin, Madison (unidata3.ssec.wisc.edu) will be permanently decomissioned on April 26, 2024.

Those using services provided by unidata3.ssec.wisc.edu can switch to using the servers described in this article.

The Unidata Program Center is partnering with UCAR's COSMIC program to provide radio occultation data provided by Spire Global. The products described below are now available via the Internet Data Distribution (IDD) network. Data are on the EXP feed with a typical total volume of 80-110 MB per hour.

The Unidata Program Center is hiring! We are looking for a scientific software developer to join our team in creating and maintaining software and data services to support the geosciences.

We are looking for a software developer to help us help our community of scientists access the Earth system science data that fuels their research. You'll have a chance work with a great team at the Unidata Program Center and and enthusiastic open source community to test, maintain, and develop Unidata software projects, focusing on our open source efforts related to the Unidata's Local Data Manager (LDM) software package and community use of the LDM via the Internet Data Distribution (IDD) system.

The Unidata Program Center will be altering the IDD NIMAGE datastream to contain all of the GOES-16 and GOES-17 Level 2 image products that are currently being being sent in the IDD NOTHER and HDS datastreams.

We plan to begin distributing a reconstituted NIMAGE feed from our top level IDD relay clusters (idd.unidata.ucar.edu and iddb.unidata.ucar.edu) in the mid-June time frame.

Students at Colorado State University

The Department of Atmospheric Science at Colorado State University (CSU) has a long history of research and education in all aspects of the atmospheric sciences. Faculty, students, and staff use a wide variety of datasets in their research and teaching, from numerical models to gridded reanalyses to radar and satellite observations to measurements collected in the field and lab. However, the students in the department recognized issues that were preventing these large datasets from being used to their full potential.

With a grant from the Unidata Community Equipment Awards program, along with a grant from the College of Engineering, the CSU Department of Atmospheric Science acquired a data storage server that makes many of these data sources readily and easily accessible to students.

Version 6.11.4 of the Local Data Manager (LDM) has been released. This version fixes and improves the defense against a denial-of-service attack, which is new with version 6.11. Getting the defense right was trickier than initially thought.

The National Centers for Environmental Prediction have begun providing Fire Weather output from selected areas of the North American Mesoscale (NAM) model via Unidata's CONDUIT feed. The additional data were added into the CONDUIT feed on September 20, 2011.
