Welcome back to AWIPS Tips! Today we are going to explore NUCAPS soundings and how to visualize, analyze, and edit them. NUCAPS (NOAA Unique Combined Atmospheric Processing System) temperature and dewpoint vertical profiles are available from polar orbiting satellites under the Upper Air > NUCAPS Soundings menu option in CAVE. These soundings are based off of satellite observations and are not dependent on any model.

The Unidata Program Center is looking for a dynamic individual to join our team as Community Services Manager.

The THREDDS development team released version 4.6.20 of the TDS on February 16th, 2022. This release contains various upgrades to third party libraries that address security exploits, as well as a bug fix in the WMS service. You can find the full release notes here.

For TDS 5.x users - the 5.4 release will be ready soon, but we are still working to address a number of reported bugs prior to the release date, which remains TBA. In the meantime, please continue to the SNAPSHOT release available on the TDS downloads page.

Welcome back to AWIPS Tips! It has been a while since we have talked about the backend portion of AWIPS – EDEX. For a brief introduction, please check out this previous entry of AWIPS Tips about EDEX. Today we are going to cover the important topic of data retention. Being mindful about data retention is important, because data can take up a significant amount of space on your server. Sometimes, that is what is expected and desired – in the case of having a long archive (longer than 5 days perhaps). But, if we’re unprepared for the amount of data that will be kept, it can end up causing all kinds of problems that can be hard to track down, and the root of the cause is your machine is running out of disk space.

Version 5.0.6 of the netCDF Operators (NCO) has been released. NCO is an Open Source package that consists of a dozen standalone, command-line programs that take netCDF files as input, then operate (e.g., derive new data, average, print, hyperslab, manipulate metadata) and output the results to screen or files in text, binary, or netCDF formats.

The NCO project is coordinated by Professor Charlie Zender of the Department of Earth System Science, University of California, Irvine. More information about the project, along with binary and source downloads, are available on the SourceForge project page.

From the release message:

Version 5.0.6 brings a few bug-fixes that only affect ncremap and ncclimo users. Others can skip 5.0.6.

Additional details are available in the ChangeLog.
