recalibrate

This program recalibrates the Zh (or Z) and nez parameters in NetCDF files. The reflectivity attribute calibration_applied is updated to reflect the total calibration applied compared to the original Chilbolton-format data.

recalibrate options file1.nc [file2.nc ...]

Options

-Zcal f
Use a calibration figure of f dB.
-Zcalfile s
Take the calibration figure from the file s, which contains a table of dates and figures. Interpolation is performed based on the date found in each file, and rounded to the nearest 0.1 dB. A calibration file could look like this:
