Iwona Wrobel works as a PhD at IoPAN and has started to work with the FluxEngine since March. Please find here her feedback

I use this application as a part of my PhD thesis, calculating CO₂ fluxes for North Atlantic and the European Arctic using different gas transfer velocity parametrizations.

So far, I performed more than 40 different runs, not all of them were successfully completed but when I wrote about this to the project PI (Jamie Shutler), whose email address I found in the “saved files” tab of FluxEngine. I didn’t wait more than an hour and Jamie wrote me back with some useful feedback on running FluxEngine.

All you need to run this program is know all specification about gas transfer velocity parameters which you can use to calculate gas air-sea fluxes. The first page which we see is “Introduction”. From there one can see the instruction set, all the steps leading to the final product. The next step is “Input datasets”. After that there is main part where we can choose various formulas to compute transfer velocity. The link to the results is sent to our e-mail address after approximately two hours. If we do not receive our results after 3-4 hours it means that runs have failed. At all times we can check our runs at the tab “Saved files”.

Not all options are working yet. For example some databases are still not implemented, some runs fail silently, not all descriptions and contact data are up-to-date but we can see that there is a good basis for the future improvements and one can see that this program is going to be very versatile.

Plots show annual net air-sea Co2 flux in four study regions. Gray line is average of 7 climatology impacts.
