We don't have access to the mobile app and we couldn't find the little circled i you mentioned. We have reviewed your argument, found that you are ignoring the suggested conversion and as a result assume that Windy.com is deliberately concealing the concentration of SO2, which at its peak exceeded a third of the estimated concentration of 100 ppm (i. e. 262 mg/m3 (100 mg/m3 × 100 ppm ÷ 38.17 ppm)) SO2 in the lower atmosphere during the life-fatal warming of early Mars.

Hi Ivo L.👋🏼

1. Your Windy.com indicate that you measure some gases concentration in mg/m2 or μg/m2, but the values measured correspond to mg/m3 and μg/m3.

   Additionally, gas concentration usually also is expressed in dimensionless ppm, which you ignore.

   Both of these are buggy.

2. It would certainly be beneficial if you added a switchable conversion from mg/m3 and μg/m3 to ppm and back. The formula is published at PPM mg_m3 converter for gases _ Teesing.
