GoalGoal •Validate Basic Spectral Moments from SPY-1 with NEXRAD
Result •SPY-1 Matches NEXRAD Reflectivity, Velocity, Spectrum Spread•SPY-1 Demonstrates Better Temporal Resolution
NOTE: Threshold Applied to SPY-1 Reflectivity Map Above Noise Floor
SPY-1 (Phased Array Radar): 1 minute scan
NEXRAD: 6 minute scan
