Outcomes/Objectives and Measures

 

STRATEGIC OBJECTIVE 3.1

Advance understanding and predict changes in the Earth’s environment to meet America’s economic, social, and environmental needs


Performance Objective: Serve society’s needs for weather and water information (NOAA)
Corresponding
Measures
  • Tornado warnings lead time (minutes)
  • Tornado warnings accuracy (%)
  • Tornado warnings false alarm rate (%)
  • Flash flood warnings lead time (minutes)
  • Flash flood warnings accuracy (%)
Changes Measures reworded as:
  • Severe weather warnings for tornadoes (county-based) – Lead time (minutes)
  • Severe weather warnings for tornadoes (county-based) – Accuracy (%)
  • Severe weather warnings for tornadoes (county-based) – False alarm rate (%)
  • Severe weather warnings for flash floods – Lead time (minutes)
  • Severe weather warnings for flash floods – Accuracy (%)
Justification NOAA changed the names of these measures to better reflect their origins in severe weather. The name change did not impact the methodology used to calculate the measures. The addition of “county-based” to the tornado measures is to distinguish them from the storm-based measures that will come online in FY 2009.
