These data represent an inventory of the national impacts of wind turbine interference with NEXRAD radar stations. This inventory was developed by the NOAA Radar Operations Center (ROC) to establish variable zones that delineate the possible impacts that wind turbines may have on radar operations. The inventory scheme includes four zones that take in to account terrain, distance, and the number of elevation angles impacted. ROC requests various degrees of consultation with the developer depending on the zone. No Build - No wind turbines permitted Mitigation Zone - Significant impacts likely Consultation Zone - Significant impacts possible Notification Zone - Impacts not likely
