IntfRemove identifies and removes interference in Titan files.

=== '''Overview''' ===

IntfRemove reads DBZ and SNR data in an input DsRadar FMQ, identifies interference and removes the interference power from the power fields, and writes the cleaned up data out to a DsRadar queue.

=== '''Prerequesites''' ===

The following items are required:

* Dual-polarimetric data via DsRadar FMQ (an NCAR file type and file used to exchange data)

=== '''Parameter file''' ===

IntfRemove uses one parameter file that includes input/output directories and interference detection parameters.

==== '''Ensure file is up to date''' ====

To obtain the default parameter file, use the following command:

<code lang="bash">/path/to/lrose/install/bin/IntfRemove -print_params > param_file_name</code>

If you already have a parameter file and simply want to check for (and add) updated parameters while retaining current parameters, use the following command:

<code lang="bash">/path/to/lrose/install/bin/IntfRemove -params orig_param_file_name -print_params > new_param_file_name</code>

==== '''Important parameters''' ====

Data Input

* input_fmq_url: path to dual-polarimetric data via DsRadar FMQ

Input Field Information

* dsr_name_DBZ: name of reflectivity field
* SNR_available: indicate whether an SNR field is available; if not, SNR will be calculated from reflectivity
* dsr_name_SNR: name of SNR field

Data Output

* output_fmq_url: path where cleaned data will saved

=== '''Running IntfRemove''' ===

To check all command line options for IntfRemove, including debugging options and file paths, type the following command into a terminal.

<code lang="bash">/path/to/lrose/install/bin/IntfRemove -h</code>

Once your parameter file is complete, use a command similar to the following to run the application:

<code lang="bash">/path/to/lrose/install/bin/IntfRemove -params param_file_name</code>

The user can also specify the location of cfradial files in the following manner:

<code lang="bash">/path/to/lrose/install/bin/IntfRemove -f /path/to/cfradial/files/ -params param_file_name</code>
