- Description
-
This collection contains the lifecycles of global atmospheric river (AR) objects. This data was produced by isolating regions of enhanced IVT transport events by applying the Atmospheric River-CONNected objECT (AR-CONNECT) algorithm. AR-CONNECT is a four-dimensional (4D) object-oriented algorithm, adapted from the CONNECT algorithm developed by a team of researchers from the University of California, Irvine [Sellars et al., 2013, 2015, 2017]. The algorithm uses a seeded region growing segmentation technique to segment AR lifecycles according to their high-intensity cores. AR-CONNECT determines the lifecycles of an AR by using a flood-filling algorithm to group discrete AR timeslices where they are contiguous over time and space. Each object has a unique ID and a set of selected characteristics.
