Radx2Grid Controlling Output

Overview

Radx2Grid offers several ways to control the output that ends up in the final file, which can help quality control the data and reduce the file size.

Censoring values

Radx2Grid offers the option to setting fields to missing values where the data meet certain criteria. This option is turned on by setting apply_censoring = TRUE in the Radx2Grid parameter file. For example, the user can quality control the files to include only the data that is most likely meteorological by censoring values based on [math]\displaystyle{ \rho_{HV} }[/math] values or PID categories.

Specifying fields

The default behavior for Radx2Grid is to interpolate all fields in the original file. If you only require a few fields, you can set select_fields = TRUE and specify a subset of fields to interpolate to the grid.

NEXRAD long-range

If you are gridding radar data from the NEXRAD network, you can choose whether to include the non-Doppler long-range sweeps. If you'd like to only include the Doppler short-range sweeps, you can set remove_long_range_rays = TRUE. Conversely, if you'd like to only include the long-range sweeps, you can set remove_short_range_rays = TRUE.
