Two of these patterns, overshooting tops (OTs) and above-anvil cirrus plumes (AACPs), are frequently observed over intense storms. Using deep learning techniques, researchers at NASA Langley Research Center developed software to automatically detect these severe storm signatures in 500m GOES satellite data collected every 5 minutes.</span></p><p style='margin:0 0 0 0;'><span></span></p><p style='margin:0 0 0 0;'><span>Emergency managers can use this raster data to quickly identify locations where severe storms likely occurred, complementing ground-based reports in regions with limited observations. Severe weather on the ground is more likely when OTs and AACPs are both detected and in areas where detections are clustered or observed repeatedly. Long, nearly straight lines of OT and AACP time-aggregated detections can indicate severe storm tracks.</span></p><p><span style='font-weight:bold;'>Suggested Use:</span></p><p><span><span>Near real-time situational awareness about locations where severe storm impacts may have occurred. Example Uses: Target additional information collection. Prioritize field activities (e.g. assessments, resource allocation).</span></span></p><p><span style='font-weight:bold;'>Satellite/Sensor/Resolution:</span></p><p><span><span>GOES-R satellite channels 13 and 15 at approximately 2 km resolution and 5-10 mins. There were some issues with some of the cases GOES files so there are times in which they were skipped. GFS tropopause temperature was also used. Data are all interpolated to 0.5 km resolution. </span></span></p><p><span style='font-weight:bold;'>Credits:</span></p><p><span><span>If you use this software in your project, please contact our team prior to publication and cite our contribution.
