Description

This collection contains global Integrated Water Vapor (IVT) objects and captures water vapor transport mechanisms important in global water vapor transport (e.g., tropical cyclones, monsoons) including life-cycle tracking. This data isolates IVT transport events by applying: The CONNected objECT, or CONNECT algorithm.

The four-dimensional (4D) object oriented algorithm was developed by a team of researchers from the University of California, Irvine [Sellars et al., 2013, 2015]. Earth science variables can be described as statistical 4D objects evolving in space (2D), time (1D), and magnitude of the selected variable (IVT in this case) (1D). The algorithm defines objects by identifying instantaneous IVT ‘‘footprints’’ (i.e., the geographic spatial patterns) and recognizes the sequential footprints from the same system with overlapped or “connected” areas in time and space. Each object has a unique ID and set of selected characteristics.
