The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.5 were released on April 5th, 2016. This is a bug fix release, and as such, the development team recommends this upgrade to anyone using the CDM or TDS.
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.4 were released on February 12th, 2016. The development team recommends this upgrade for anyone using the CDM or TDS.
This is Part 2 of a series of notebooks showing how to plot GINI-formatted satellite data from a THREDDS server using MetPy and Siphon. In Part 1 we covered how to access and parse the data file. In this part, we cover:
This is the first of what we hope will be a series of posts showing how to use Python for weather analysis and create graphics for a variety of purposes. In this two-part post, we demonstrate plotting a water vapor satellite image, specifically using GINI formatted data. GINI is the format currently used for satellite data transmitted across NOAAPORT, and is available on Unidata's demonstration THREDDS server. This first part focuses on accessing the data using Siphon and MetPy; the second part will introduce plotting using CartoPy.
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.3 were released on August 31st, 2015. The development team recommends this upgrade for anyone using the CDM or TDS.
Editor's note: Josh Clark was a Unidata Summer Intern in 2015. He graduated from the University of Northern Colorado (UNC) in the spring of 2015 with a B.S. in Meteorology, and is headed to the graduate program at San Jose State's Fire Weather Research Lab starting in the Fall of 2015.

It is hard to believe my time here at Unidata has come and gone so quickly! Next week, I imagine it will be back to the “harsh” reality of being a student — sitting on a beach somewhere near Monterey or perhaps fly fishing the Sierras over the next twenty days awaiting the start of my first year of graduate school at San Jose State. What a terrible reality that will be!
This experience at Unidata and UCAR has been an incredible opportunity and I am privileged to have been afforded these ten weeks. When I started here, I envisioned an entirely different internship than what previous interns had completed. Rather than developing one particular project, I focused my time on gaining a greater understanding of software engineering as a whole and contributing to existing Unidata projects. I found a comfortable spot working with Unidata Python developers Ryan May and Sean Arms, and within one week I had learned a great deal about unit testing, code health, automated testing, and version control. Later, I would implement these principles in my first Python library, MesoPy.
Digital Object Identifiers (DOIs) are now available for select Unidata technologies. We encourage you to use the DOIs when citing or otherwise referring to these technologies, because they provide a mechanism by which the information referred to can be found even if the web address underlying the DOI changes over time.
DOIs are strings of characters assigned by a registering organization to uniquely idenfity a digital resource such as a document, software package, data set, or other electronic “object.” DOIs have been created for the Integrated Data Viewer (IDV), the THREDDS Data Server (TDS), and the netCDF libraries. The DOIs are assumed to persist indefinitely, so they are preferable to using standard URLs in your citations. The DOIs are:
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.2 were released on June 9th, 2015. The development team recommends this upgrade for anyone using the CDM or TDS. The latest update can be downloaded from:
THREDDS development is now switching to version 5.0 which will require Java 8. Version 5 is a major upgrade and some of the APIs will change. Deprecated classes will be moved to a legacy jar and will not be supported. If you are a developer, you will need to test the new version against your code. We expect to have an alpha release out by July for that purpose.
