Estimation of the parameters of a simple model of thorium and particle cycling in the ocean water column, based on a fit to radionuclide and particle data from the US GEOTRACES North Atlantic Section (GA03)

<p>This dataset contains model code and output from a thorium and particle cycling model.&nbsp;</p>

<p>The model code and documentation are available for download as a .zip file:&nbsp;<a href=\"http://datadocs.bco-dmo.org/docs/GEOTRACES_Particle_Dynamics/data_docs/Lerner_Th_P_inverseModel.zip\" target=\"_blank\">Lerner_Th_P_InverseModel.zip (2.6 MB)</a></p>

<p>Model output data are available by clicking the \"Get Data\" button above.&nbsp; These data are parameter estimates from fitting the model to radionuclide and particle data from the US GEOTRACES North Atlantic Section,&nbsp;not samples collected in the field.&nbsp;</p>

<p>Both the model and inverse method are described in detail in the model manual “<a href=\"http://datadocs.bco-dmo.org/docs/GEOTRACES_Particle_Dynamics/data_docs/Lerner_Th_P_inversion_manual.pdf\" target=\"_blank\">Manual of Matlab Code: Nonlinear Inversion of Thorium and Particle Data</a>,” as well as in Lerner et al., 2017.&nbsp;&nbsp;&nbsp;This document describes how to use the routine submitted here to fit a 1-d thorium and particle cycling model to radionuclide and particle data</p>

<p>These data and model were&nbsp;published in:</p>

本数据集包含钍与颗粒物循环模型的模型代码与模型输出结果。

模型代码与说明文档可通过以下.zip压缩包下载：<a href="http://datadocs.bco-dmo.org/docs/GEOTRACES_Particle_Dynamics/data_docs/Lerner_Th_P_inverseModel.zip" target="_blank">Lerner_Th_P_InverseModel.zip（2.6 MB）</a>

模型输出数据可通过点击上方的‘获取数据’（Get Data）按钮获取。此类数据为将模型拟合至美国GEOTRACES北大西洋断面的放射性核素与颗粒物数据后得到的参数估计值，并非野外采集的样品数据。

本模型与反演方法的详细说明可参阅模型手册《<a href="http://datadocs.bco-dmo.org/docs/GEOTRACES_Particle_Dynamics/data_docs/Lerner_Th_P_inversion_manual.pdf" target="_blank">Matlab代码手册：钍与颗粒物数据的非线性反演</a>》，以及Lerner等人2017年的研究成果。该手册阐述了如何使用本次提交的程序，将一维钍与颗粒物循环模型拟合至放射性核素与颗粒物数据。
