Noble gas global observations used in the ECCO noble gas model and simulations decomposed to isolate bubble-mediated gas exchange (Noble gas modeling project)

<p>This dataset includes:<br />
1) noble gas observations used in the ECCO noble gas model. They were collected globally at sea and were analyzed by mass spectrometry.<br />
(2) model&nbsp;simulations decomposed to isolate bubble-mediated gas exchange.</p>

<p><strong>Noble Gas Observations:</strong><br />
The observation data&nbsp;is provided in MATLAB format: <a href=\"http://dmoserv3.bco-dmo.org/data/Noble_Gas_Modeling/NobleGasDB.mat\">noblegasDB.mat (download here)</a>&nbsp;(size = 94 KB)<br />
The variables are a MATLAB table ‘NGall’ and a list of original references ‘NGprojects’<br />
The served data is provided in jgofs format with the columns slightly rearranged for database best practices.</p>

<p><strong>Global Model Simulations:</strong></p>

<p>The simulation&nbsp;file is provided in MATLAB format: <a href=\"http://dmoserv3.bco-dmo.org/data/Noble_Gas_Modeling/ECCOv2_NobleGases.mat\">ECCOv2_NobleGases.mat (download here)</a> (size = 1 GB)</p>

<p>Noble gases and nitrogen were simulated in the Estimating the Circulation &amp; Climate of the Ocean (ECCO) global ocean state estimate utilizing a matrix-free Newton–Krylov (MFNK) scheme to efficiently compute the periodic seasonal solutions for noble gas tracers.</p>

<p>Original simulations:<br />
sim1 = diffusive gas exchange only<br />
sim2 = diffusive gas exchange and bubble injection<br />
sim3 = diffusive gas exchange and bubble exchange</p>

<p>DG = sim1<br />
IG = sim2-sim1<br />
EG = sim3-sim1</p>

<p>For each gas ‘G’ total gas concentration is calculated as Gsol(S,T) * (AG + BG + CG)</p>

<p>DG is results of the simulation with no bubbles, while IG and EG are the isolated contribution from bubble injection and bubble exchange, respectively.</p>
