Abstract
Tropical cyclones regularly form during the north Atlantic `Hurricane Season' (June-November) and their typical trajectory follows the east coast of the United States (US). These cyclones can generate billions of US dollars of damage as they pass over highly urbanized areas of the US east coast. The dataset contains numerical simulations of water quality impacts during Hurricane Irene (2011) in a large coastal-plain estuary (Chesapeake Bay, USA). The simulations are produced with the Regional Ocean Modeling System (ROMS) that is in turn forced by an ensemble of atmospheric simulations of Irene (50 realizations in the ensemble) conducted with the atmospheric component of the global model E3SM. The result is a distribution of water quality impacts (changes in turbidity, stratification, oxygen and other metrics) as a function of 50 `Irene-like' hurricanes with slightly different trajectory and intensity. The simulations are archived in the self-documented NetCDF format with each files containing the necessary metadata. The dataset includes the computer code (and all its configuration), the inputs necessary to re-run ROMS and reproduce the numerical simulations, as well as the actual outputs from ROMS. The dataset (~75 GB in size) includes a README file containing a list of all the files and additional background information on each of them.
