Supporting data for: "Impacts of Eastern Arctic Eurasian Basin Water Mass Properties on the AMOC and Beaufort Sea Atlantic Water Layer"

This repository contains the key supporting data (in the netcdf format) for the following paper:Wei, X., Zhang, R. Impacts of Eastern Arctic Eurasian Basin Water Mass Properties on the AMOC and Beaufort Sea Atlantic Water Layer In this study, Control and Robust Diagnostic Calculations (RDC_Eura) ensembles are conducted using a coupled climate model (GFDL CM2.5). The anomaly is defined as the difference between the RDC_Eura and Control ensembles (anomaly = RDC_Eura - Control). This paper investigates the impacts of the eastern Arctic Ocean water mass properties on the Atlantic Meridional Overturning Circulation (AMOC) and the Beaufort Sea thermal structure. Descriptions of data files in this repository: Main figures: 1. Figure 1(c-d) in the paper.
