Beginning with netCDF version 4.8.0, the Unidata NetCDF group has extended the netcdf-c library to provide access to cloud storage (e.g. Amazon S3) by providing a mapping from a subset of the full netCDF Enhanced (aka netCDF-4) data model to a variant of the Zarr data model that already has mappings to key-value pair cloud storage systems.
The MetPy development team is looking for anyone who has used MetPy to take the 2020 MetPy Users Survey. The survey should only take approximately 5 minutes and is completely anonymous.
Unidata's AWIPS development team is looking for input from users of Unidata's AWIPS distribution. They'd like to learn about which datasets you're currently using or would like to use, and which features of AWIPS are most important for your workflows.
The 100th American Meteorological Society Annual Meeting in will be held 10–14 January 2021 in New Orleans, LA. This year's theme is “Strengthening engagement with communities through our science and service.” The submission deadline for abstracts is 3 August 2020. Abstracts for the 20th Annual Student Conference are due by 21 September 2020.
The American Geophysical Union's 2020 Fall Meeting in will be held 7-11 December 2020 in San Francisco, CA. This year's theme is “Shaping the Future of Science.” The submission deadline for abstracts is 29 July 2020.
Organizers of the AMS meeting are still in the process of determining how best to hold the 2021 meeting. AGU organizers have declared that the 2020 Fall meeting will be “mostly virtual” but may also organize in-person regional events. See the full post for additional information.
The Unidata THREDDS Development Team released updated versions of the THREDDS Data Server (TDS) and netCDF-Java/Common Data Model (CDM) library on June 17, 2020. In addition to feature enhancements, these releases contain a variety of updates to third-party libraries, including security updates. They also address a problem in previous versions that could lead to data returned by some NetcdfSubsetService (NCSS) requests being corrupted. While the circumstances under which the problem occurs are very specific (and rare), because the possibility of data corruption exists the development team strongly recommends these upgrades to anyone using netCDF-Java/CDM or TDS. TDS administrators who are not able to upgrade immediately should disable the NetcdfSubsetService until it is possible to do so.
The netCDF-Java ucar.nc2.util.DiskCache2 class method for generating unique file names is capable of producing identical names if called in quick succession. While the circumstances under which the problem occurs are very specific (and rare), because the possibility of data corruption exists the development team strongly recommends that anyone using netCDF-Java/CDM or TDS upgrade immediately.
