<div>I was wondering if and when you plan to make available data and instructions to reproduce the v4 release 5 solution. Usually, there's a very convenient howto document to reproduce results but the most recent one I could find is for V4r4.</div>

<div>One caveat:</div>
<div>The period of 1992-2017 is fully optimized </div>
<div>while year 2020-2024 is not optimized</div>
<div>(simply an iteration 0, ie, </div>
<div>By applying the climatological seasonal mean of previous adjustments to raw forcing).</div>
<div>Ou Wang is working on a fully optimized 1992-2024 state estimate </div>
<div>and it’s coming soon ...</div>

<div>Hope it works for you.</div>
