Overshooting Convective Cloud Top Detection A GOES-R Future Capability Product 1995-2011 GOES-East (-8/-12/-13) OT Detections at Full Spatial and Temporal Resolution, 0.25 Degree Resolution Grid Animation Normalized By The Number of Scans In Each Two-Hour Period Kristopher Bedka (SSAI @ NASA LaRC): [email protected] in collaboration with UW-CIMSS and NASA LaRC • A method to objectively detect overshooting convective cloud tops (OTs) and the enhanced-V signature has been developed in support of the GOES-R Aviation Algorithm Working Group • Publications have shown good correlation between OT detections, severe weather reports, objective in-situ aviation turbulence, LMA total lightning observations, and a long-term climatology of cloud-to-ground lightning • The OT detection product has been evaluated within the NOAA Hazardous Weather and Aviation Weather Testbeds and the 2012 European Severe Storms Laboratory Testbed • Testbed evaluations indicate that the product is consistent in accurate detection of OT signatures, but detection capability is impacted the relatively coarse spatial and temporal resolution of current GOES. Analysis shows that detection rate may increase ten-fold when the algorithm is applied to 2 km and 5 min ABI data • Evaluations also suggest that the product can provide valuable situational situational awareness over data-rich regions and could be used to pinpoint hazardous areas within thunderstorms over data-poor land and ocean regions
