collecting data from space = good
I think that collecting data from space and producing maps is a VERY good thing.
Down side, we won't have any starting point for comparable data. Trying to compare space data to on-the-ground trends would tend towards apple/orange comparisons.
Still it should help show things like whether active volcanoes ARE actually pumping huge levels of CO2 into the atmosphere (which i believe is the case).
This would also help with monitoring obviously-man-made CO2 concentrations in low-rain areas away from coastlines, taking wind and weather into consideration. It would help to show whether (or NOT, as I would claim) the models of CO2 production and depletion actually fit reality, and whether atmospheric CO2 concentrations are really affecting temperature [you could correlate concentration to cooldown rate at night when there are few clouds and no wind, for example).
Ideally this data would be available for EVERYONE so that citizen-scientists can look at it, etc. as well as college students and profs.
I just hope that they would not in any way filter the data to match a political position. Just raw and available to EVERYONE
(Maybe the other project can do the same? Save money and consolidate the mssions?)
