Discussion > OCO-2 and "Data Fusion"
"I'm suspicious + cynical about groomed data like this especially on this subject from the stable operated by the insufferably pompous Mann acolyte Gavin Schmidt."
I am only 97% suspicious and cynical, but if they were to produce some kind of proof, rather than fancy new presentations, I might be less cynical.

The 3-D presentation made me a little suspicious; the view sank down to show the picture from the south, thus the higher-altitude CO2 gives the impression of it being higher-latitude – but is it? Methinks that there is some deception intended with this presentation. Certainly, when the final view reverts to a top-view, the initial paltry amount of blue, representing lower CO2, expands an awful lot, to cover much of the northern hemisphere.

We think you won't understand the data so we made a cartoon for you

22 months later and there is a new WUWT post on this topic

Maybe someone can explain to me what's going on with this
Cos I don't see how you can reduce some massively complex dataset to a simple 2 dimensional map ?
If you look at a location you have an column above it.
Imagine it as a series of a thousand cubes from ground to upper atmosphere
and what we are doing is counting up the CO2 percentage in each cube
.. and #1 getting an AVERAGE CO2 reading for that moment
.. and then #2 taking all the moments in a year and getting an average for the whole year
Hows that work, cos you get all different winds at each level each day
If I draw a column across the earth from Scunthorpe to London and I count all the cars that are passing in that column what does that tell us ?
(I am not talking about a rod from Scun to London,)
We'll get a count cos there are roads crossing that column
each road will have a kind of pattern
But there are variables like weather , like football matches, festivals, road accidents
Will the count tell us anything about cars leaving Scunthorpe ?
It will tell us it is in a country where there not zero cars
.. I am not sure much else

The point I was making is (I think...) that Eric Swenson made an effort to replicate the colour palette that GISS-NASA used in their model to allow direct comparison between modelling and observation - and the NASA confection didn't stand the comparison with observed / measured values.
Subsequent treatment by NASA of the OCO-2 data has, as far as I'm aware been confined to mixing it with other data and skewing the view angles .... - did they add a portentous soundtrack ? - I can't remember - oh, and ignoring it .... - actually it's all been mainly ignoring it.....
The photosynthesis fluorescence data has also been largely ignored as it must be showing some of the greening / growth that is obvious from other remote sensing missions.

NASA have released a new visualisation of global CO2 concentrations in the atmosphere.
I never expected them to publish an intuitive navigation of the OCO-2 data in say earth.nullschool style clicky-zoomy globe thingy - which would be accessible to the average public person ...
They seem to have gone for a model fusion - which is a fashionable visualization technique - beloved of the military at the moment...
I'm suspicious + cynical about groomed data like this especially on this subject from the stable operated by the insufferably pompous Mann acolyte Gavin Schmidt.
I hope my cynicism is misplaced and they've done a bang up job of honest presentation.
WUWT has a post up
The NASA visualisation seems to pick 397.5ppm as the "right amount of CO2" and I can't say I'm impressed with the colour mapping and data transparency values used - but then I'm biased.....
There's more to come..... I just wonder why they didn't chose to release the data in a format that allows open source software like earth.nullschool.net to relatively trivially allow data exploration...
