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.
