Unit Testing in the netCDF-c library using cmake

It appears to be the case that all current tests in the netcdf-c source tree are integration tests. That is they only access the library using calls to the externally visible API.

The DAP4 code testing is different in that it includes (for the first time) unit tests. These tests reference code that is considered internal to the library. For the library generated under autoconf, this is not a problem because those symbols are visible in the library: nothing is hidden.

AWIPS NEXRAD Level 3 Rendered with Matplotlib

Shown here are plots for Base Reflectivity (N0Q, 94) and Base Velocity (N0U, 99) using AWIPS data rendered with Matplotlib, Cartopy, and MetPy. This example improves upon existing Level 3 Python rendering by doing the following:

  • Display scaled and labeled colorbar below each figure.
  • Plot radar radial images as coordinate maps in Cartopy and label with lat/lon.
  • 8 bit Z and V colormap and data scaling added to MetPy from operational AWIPS.
  • Level 3 data are retrieved from the Unidata EDEX Cloud server (edex-cloud.unidata.ucar.edu)
  • Raw HDF5 byte data are converted to product values.

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.

There seems to be agreement inside Unidata that we need to begin rethinking that architecture to adapt to the realities of the cloud.

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.

Colored Temperature Obs in CAVE D2D (NMAP2-style)

One of the new data visualizations available in the upcoming AWIPS 16.2.2 release is a recreation of the legacy GEMPAK/NAWIPS colored temperature ("color_temp") bundle.
