Radar data measures reflectivity, not precipitation, which can lead to misinterpretation of color coding in weather apps. Important metrics to analyze include correlation coefficient (RHOHV), radial velocity (VRAD), and differential reflectivity (ZDR) to assess accuracy. There is a delay in radar data, typically between 5 to 10 minutes, requiring developers to account for latency. To create user-friendly interfaces, it's important to animate storm movement and provide directional indicators to enhance situational awareness.
Radar does not actually "see" rain, but rather measures reflectivity. It doesn't mean red indicates danger or green indicates light rain.
Radar is limited by latency; it doesn't stream live video, which creates a delay of 5-10 minutes that developers must account for.
The motion of storms is crucial. A single frame can mislead users if direction and speed aren't considered. Incorporate animations and storm vectors.
Using correlation coefficients can help distinguish between actual precipitation and non-meteorological targets like birds or bugs.
