Western Pacific Atmospheric River Object Data from MODE detection software using West-WRF, GEFS, and MERRA-2

About this Collection

The .tgz files contain NetCDF files of atmospheric river (AR) objects as processed through the Method for Object-based Diagnostic Evaluation (MODE; Bullock et al. 2016) software. MODE is part of the Model Evaluation Tools (MET; https://dtcenter.org/community-code/model-evaluation-tools-met) package provided by the National Center for Atmospheric Research (NCAR). ARs are narrow areas of intense moisture transport that can be identified using gridded fields of integrated vapor transport (IVT) from a numerical weather prediction model and/or analysis (described below). Objects are used to evaluate the forecast skill of the AR over an 11 year (2006-2017) period during the cool season (Dec-Mar). View this collection on the contributor's website.
