The Geomagnetic Kp-Index Aurora Sizing Ratio Calculator evaluates comparative numeric relationships between geomagnetic activity, observation latitudes, and atmospheric damping factors.

### How the Ratio Calculator Computes Metrics This tool provides a rapid three-parameter numeric analysis workspace for evaluating observational variables: - **Primary Load / Metric ($V_1$)**: Represents baseline observation latitude or geomagnetic flux intensity (default 100). - **Operating Coefficient ($V_2$)**: Scaling coefficient or solar wind velocity modifier (default 20). - **Control Factor ($V_3$)**: Denominator damping factor or cloud cover index (default 5, clamped to a minimum of 0.01 to prevent division by zero). - **Main Output Index**: Evaluated using direct multiplicative ratio scaling: $$\text{Main Index} = \frac{V_1 \times V_2}{\max(0.01, V_3)}$$ - **Secondary Metric**: Computes the geometric root product: $\sqrt{\max(0, V_1 \times V_2)}$. - **Efficiency Metric**: Calculates normalized percentage distribution: $\min\left(100, \max\left(0, \frac{V_1}{V_1 + V_2} \times 100\right)\right)$.

### Worked Numeric Calculation Using the default configuration values: - **Primary Value ($V_1$)**: 100 - **Coefficient ($V_2$)**: 20 - **Factor ($V_3$)**: 5 - **Main Index Calculation**: $$\text{Main Index} = \frac{100 \times 20}{5} = \frac{2000}{5} = 400.00$$ - **Secondary Geometric Metric**: $\sqrt{100 \times 20} = \sqrt{2000} \approx 44.72$ - **Calculated Efficiency**: $(100 / 120) \times 100 = 83.33\%$

### Client-Side Numeric Evaluation All calculations update dynamically on every keystroke in your web browser. No telemetry, observation notes, or geographic inputs are transmitted over the web.
