Abstract

Here present model output from a data-assimilating model of the ocean aluminum (Al) cycle. The model simulates inputs of Al from atmospheric dust, and internal cycling due to reversible scavenging and biological cycling, and assimilates data from the GEOTRACES archive. Full code and inputs for the model can be accessed at Zenodo (doi: 10.5281/zenodo.10139317). This file contains the aluminum model-predicted aluminum distribution from the fully-optimized model, as well as 60 different estimates ...

Data are presented in both the original Matlab data format (file "Xu_2021_model_output.mat") and a non-proprietary plain-text format "Xu_2021_model_output.zip" which contains a .txt file for each variable stored in Xu_2021_model_output.mat.  See file descriptions for more information about the structure of these files.

Relationship Description: The model was solved for the steady-state aluminum distribution, which was then compared to observations from the GEOTRACES IDP2017 (GEOTRACES_IDP2017_v2_Discrete_Sample_Data) to optimize uncertain parameters.
