I try to perform optical calibration on Pleiades images taken in last september above Lorient and its bay. About the TOC calibration level, i wondered where to find datas as I cannot have aeronet file to download on my location.
But i would like to have your advice about the website below (the page is just an example) :
Here, I can download several kind of datas about atmospheric conditions. Of course, dowloaded datas are not very spatially precise, but it seems to provide good daily global datas on my location, for aerosol optical thickness, ozone amount and water vapour. And you could note that ozone amount are in dobson units which must be converted to atm-cm (100 DU ~ 0,100 cm-atm).
And about the aerosol model, a good choice seems to be maritime, for areas located along the coast and the small Island of Groix.
So, my two questions are :
- Is this website relevant to get atmospheric datas on a specific location without aeronet file ?
- About aerosol models (6S) : What do we mean exactly by maritime model ? Does it depend on salinity ? To how much distance from the coast could we use the maritime model for an area ?
Thanks by advance,
