Animation Shows One Year of CO2 Swirling Through the Atmosphere

In summary: Oceans of the southern hemisphere are either (net) releasing more CO2 than expected, or the much larger than expected over land hotspots in the southern hemisphere have generated much larger southern hemisphere concentrations across the oceans than expectedThe oceans seem to be absorbing a lot more CO2 than we'd expect given that they make up about two thirds of the Earth's surface.d) the northern hemisphere is (net) releasing much less CO2 than expectedThe northern hemisphere has been releasing less CO2 than we'd expect, but it's tough to say how much of that is due to the data and how much is due to other factors (such as the Arctic ice pack).e) the south east China CO2

It's interesting how plants manage to absorb so much carbon dioxide during the summer. Thanks.

I was just about to post this video! Very interesting! I also liked how much plants helped in the summer and was surprised by the carbon monoxide offset in the other half of the globe.

This is beautiful.

So the first data from the OCO-2 satellite are in from NASA: http://science.nasa.gov/science-news/science-at-nasa/2014/19dec_oco/

Clearly this map is not directly comparable to the simulation video posted above:
a) the data image is an average from October 1st to November 11th 2014 whereas the simulation video is made up of day long segments from based on 2006 atmospheric circulation data
b) the scales are different
c) absolute CO2 concentrations were higher in 2014 than in 2006
d) the video also includes carbon monoxide concs on another scale which somewhat confuse the picture

BUT to the layman (me) it does seem like the simulation has done a relatively poor job of simulating the relative CO2 concentrations represented by the data. If you stop the video at 2:28 representing the 21st October 2006 (roughly the midpoint of the data period from the OCO-2 picture):

I would argue the following arguments are fair:
a) South America and Southern Africa have much larger concentrations than the simulated hotspots
b) S.E. Asia has a completely unexpected high CO2 concentration
c) the Oceans of the southern hemisphere are either (net) releasing more CO2 than expected, or the much larger than expected over land hotspots in the southern hemisphere have generated much larger southern hemisphere concentrations across the oceans than expected
d) the northern hemisphere is (net) releasing much less CO2 than expected
e) the south east China CO2 hotspot is well represented in the model

I'm really looking forward to seeing how the data from OCO-2 develops over the next year and whether the seemingly reasonable correlation between solar induced flourescence continues throughout the year . . . although confusingly the time period for this map is August to October 2014:

It's tough to say what's going on without knowing how air masses were moving (stationary highs, lows yielding stagnation, or seasonal "winds" coming through and moving the seasonal burning CO2 out of an area quickly.

Again, without correlating this to movements and mixing of air masses, it's "up in the air" as to what it actually means.
 

Related to Animation Shows One Year of CO2 Swirling Through the Atmosphere

1. What is the purpose of the animation "One Year of CO2 Swirling Through the Atmosphere"?

The purpose of this animation is to visually represent the movement and concentration of carbon dioxide (CO2) in the Earth's atmosphere over the course of one year. It is based on real data collected by NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite, and aims to show the global circulation and transport of CO2 in the atmosphere.

2. How was the animation created?

The animation was created using data from NASA's OCO-2 satellite, which measures the concentration of CO2 in the Earth's atmosphere. The data was then processed and visualized using specialized software to create the swirling motion and color-coded representation seen in the animation.

3. What can we learn from this animation?

This animation can teach us about the global patterns and movement of CO2 in the atmosphere. It highlights areas of high and low CO2 concentrations, as well as how the gas is transported and mixed throughout the year. It also helps us understand the role of natural processes, such as photosynthesis and ocean currents, in regulating CO2 levels in the atmosphere.

4. How does CO2 affect our planet?

CO2 is a greenhouse gas that traps heat in the Earth's atmosphere, contributing to the warming of our planet. Increased levels of CO2 in the atmosphere can lead to climate change and other environmental impacts, such as ocean acidification. This animation provides a visual representation of how CO2 is distributed and transported in the atmosphere, helping us understand its potential effects on our planet.

5. Is the data in this animation accurate?

Yes, the data used in this animation is based on real measurements collected by NASA's OCO-2 satellite. The satellite uses highly accurate instruments to measure the concentration of CO2 in the atmosphere and has been validated by ground-based measurements. However, it is important to note that the animation is a simplified representation and does not show the full complexity of CO2 movement and distribution in the atmosphere.
