New TDS Cloud Architectures: Proposal 1

The Thredds Data server (TDS) was designed to operate in a client-server architecture. Recently, Unidata has moved TDS into the cloud using its existing architecture.

From GEMPAK to AWIPS: Building the NSHARP Dynamic Library on OS X

A little known fact in the world of AWIPS(II) is just how dependent the system still is on NAWIPS-GEMPAK. The entire National Centers Perspective is dependent on pre-built shared object files for 64-bit Linux, which means that all of the D2D plugins which extend NSHARP (for bufr obs, NPP profiles, forecast models, etc.) also depend on these libraries.

This dependency has prevented use of the NSHARP plugin in the first release (15.1.1) of the OS X CAVE client. These are the steps taken to build NSHARP and GEMPAK libraries for OS X AWIPS 16.2.2.

Upload and Download Support for TDS

For version 5.0.0, it is possible to configure TDS to support the uploading and downloading of files into the local file system using the "/thredds/download" url path. This is primarily intended to support local File materialization for server-side computing. The idea is that a component such asJupyter can materialize files from TDS to make them available to code being run in Jupyter. Additionally, any final output from the code execution can be uploaded to a specific location in the TDS catalog to make it available externally.
