Crate nexrad_process 

Processing algorithms for NEXRAD weather radar data.

This crate provides processing traits and algorithms that operate on the field types defined in nexrad_model. The core abstraction is the SweepProcessor trait, which transforms one SweepField into another. Processors can be composed into pipelines using SweepPipeline.

Architecture

Three processing traits cover different scopes:

• SweepProcessor — single-sweep algorithms (filtering, smoothing)
• ScanProcessor — multi-elevation algorithms (velocity dealiasing)
• ScanDerivedProduct — produces a CartesianField from a full scan (composite reflectivity, VIL)

Example

use nexrad_process::{SweepPipeline, filter::ThresholdFilter};
use nexrad_model::data::{SweepField, Product};

let field = SweepField::from_radials(sweep.radials(), Product::Reflectivity).unwrap();
let filtered = SweepPipeline::new()
    .then(ThresholdFilter { min: Some(5.0), max: None })
    .execute(&field)?;
