Current National Network Quality Control Checks
1. Is all required metadata present and variables are within limits (-90<lat<90)
2. Is the radial over water?
3. Are the radials below the threshold– East and Gulf Coast 3 m/s– West Coast 1 m/s

Red Points are the 6 km National Network grid
Black Points are:1) Within 150 km of the
coast
AND
2) Water depths greater than 15 m
