4 months ago Hi @JohnThomasSEAS, this has been a problem for a while and we should fix it. The issue is that our bounds can't keep up with the rising methane background. The current vmax and vmin are suitable for 2018, but not 2023 or 2024. I think if we just expand the range we may miss out on some of the interesting gradients being smoothed. But we could have a dynamic 50ppb range of vmin/vmax centered on the mean/median values tropomi concentrations. Thoughts?
(This is the cell that's titled: "Mean TROPOMI XCH4 columns on 0.1 x 0.1 grid")
It may just be an issue with the inversions that I've run (not many), but I've consistently noticed that this plot's color range is overly saturated on the high end (essentially all cells are maxed out in value), indicating that it might need to be adjusted upwards. The current default min/max is 1800/1850 ppb, I suggest it be moved to 1800/1950ish? Attached is a plot with those ranges, which gives a more nuanced and accurate view of spatial trends.
Maybe there's a way to set vmin and vmax on the fly using min/max values from the data itself instead of static values?
