Available Pro Radar Products

The following radar products are available in RainViewer:

DBZH - Reflectivity

Standard reflectivity scan. Tracks horizontal precipitation intensity. >50 dBZ suggests hail or severe storms.

DBZV - Vertical Reflectivity

Measures vertical radar returns. Useful for storm structure analysis.

VRADH - Velocity

Shows how fast precipitation particles are moving relative to the radar.

RHOHV - Correlation Coefficient

Identifies uniform vs. mixed targets. Low values may indicate debris or hail.

ZDR - Differential Reflectivity

Difference between the horizontal and vertical reflectivity.

KDP - Specific Differential Phase

Detects intensity of precipitation.

PHIDP - Differential Phase

Raw phase data your radar collects before it calculates KDP.

SNR - Signal-to-Noise Ratio

Radar clarity check. Higher values mean cleaner data.

HCLASS - Hydrometeor Classification

Advanced ID of rain, hail, snow, graupel, or non-weather objects.

WRADH - Spectrum Width

Shows wind turbulence. High values? Think shear or gust fronts.

PMI - Polarimetric Meteo Index

Combines multiple radar variables to flag storm features.

SQIH - Signal Quality Index

Summarizes radar return reliability. High SQI = clean, trustworthy echo, low SQI = noisy or suspect return.

Total Velocity

Sum of all detected motion. Helps analyze overall wind dynamics.

Total Hail Index

Scores hail likelihood. High = damaging hail potential.

LOG - Logarithmic Reflectivity

Alternative reflectivity scale to highlight fine gradients.

CCORH, CCORV - Corrected Correlation

Corrected correlation for horizontal and vertical scans. Helps refine clutter filtering.

CPAH, CPAV - Horizontal & Vertical CPA

Confidence index for horizontal and vertical polarimetry. High = reliable returns.

VRADV - Vertical Velocity

Tracks vertical wind toward/away from radar. Useful for storm structure.

WRADV - Vertical Spectrum Width

Measures wind turbulence in the vertical plane. Can flag strong updrafts.

CSP - Doppler-Channel Clutter Signal

Measures the strength of stationary or slow-moving radar returns.

TH, TV - Horizontal & Vertical Linear Total Power

Tracks raw signal strength in the horizontal and vertical channels. Used for calibration and quality control.
