FLEXTRKR

Mesoscale convective system (MCS) database over United States

PI

Purpose

The mesoscale convective system (MCS) database over contiguous United States (CONUS) is a long-term (2004-2017) high-resolution (4 km, 1 hourly) storm system data set that tracks individual MCS events. The MCS database is produced by applying an updated version of the FLEXible object TRaKeR (FLEXTRKR) (Feng et al. 2018) algorithm described in detail in Feng et al. (2019) to the NASA Global MergedIR infrared brightness temperature (Janowiak et al. 2001) and the GridRad mosaic 3D NEXRAD radar data set (Bowman and Homeyer 2017).
