Part Time Radar Availability

Part-time Windfinding Radars have routine periods when weather watch coverage is not available. This normally occurs, up to 4 times a day, for approximately 1.5 hours as shown in the table below. During these periods these radars will be engaged in tracking of high-level balloons for the measurement of winds in the upper atmosphere.
