<p class="MsoNormal"><span lang="EN-GB" style="mso-fareast-language:EN-US">In the light of the discussion around the Sentinel-2 pre-processing wrapper script, I was wondering if you plan / were considering to add a multi-temporal approach to cloud detection
[1,2,3] to your module?<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="mso-fareast-language:EN-US">If your GSoC was a "pick and choose event”, I would personally be more than satisfied with an “i.atcorr.params” module (or the like) that compiles 6s input file (maybe just with simple
user input on geometrical conditions, aerosol model, …) instead of a wrapper for a full preprocessing chain, if that allows you to work on a (at least preliminary) multitemporal could detection procedure…<o:p></o:p></span></p>
