Characteristics of eddying AMOC: Transient tracers and eddy transport tensors.

This data set contains results from numerical simulations used to study the importance of mesoscale currents (“eddies”) in the Atlantic Meridional Overturning Circulation (AMOC) pathways and timescales. The study is based on offline simulations of two Boundary Impulse Response (BIR) tracers, which quantify the importance of the Atlantic tracer exchanges with the high-latitude atmosphere in the north (NBIR tracer) and with the Southern Ocean in the south (SBIR tracer). Two types of numerical simulations are used: one with the full advection (“FULL_ADV”) and another with the large-scale time-mean currents and no mesoscale eddies (“MEAN_ADV”). The data in this repository include comprehensive transport tensors and several key tracer diagnostics (see table of contents). Due to a large size of the model forcing fields and outputs, these data are available upon request from the corresponding author. These data are associated with the article: Kamenkovich, I., and Z.
