Currently, the
.a1xprecipradardatastream has mismatched netcdf encodings for missing value codes (i.e. the encoding on the file does not match the MVC used within the arrays and does not match our CMAC product DOD). Additionally, the.a1datastream uses integer times, which results in ~36-37 azimuths angles (depending on elevation scan) (and thus roughly 784k gates) containing the same exact time.To conform to ARM standards, two functions are written to correct and create a
.b1level "glue file" which corrects the encodings and adds an offset (in nanoseconds) to each specific gate within the merged volume.To overcome writing to existing files, updated xarray datasets are first written to a temporary directory than moved to the data directory for the given month. This has been tested within this notebook to work with the Dask cluster on Cumulus.
