And why? Why do we need to study clouds?

So in the end, the overarching goal of the CLOUD experiment is to improve our uncertainties in climate predictions.

We, as human beings, we warm our climate by emitting CO2 and other greenhouse gases, but we also produce a certain amount of global cooling.

Now, clouds, as we know, are, they tend to be white, right? So clouds tend to have a cooling effect on our atmosphere, and they do that because as we receive radiation from the sun, and sunlight hits the planet, if it hits a cloud or a white surface, a large fraction of that is being reflected back into space.

So overall, if you have more clouds, you have a cooler climate.

So for us to actually understand climate change and to make reliable predictions for how the climate will evolve in the future, we need to understand how our clouds and the cloudiness of our atmosphere will behave in the future and has behaved in the past.

So if we want to understand what our impact on the cloudiness of our planet is, we need to understand all of the microphysical processes that are involved in making clouds and making aerosol particles, so that we can feed this information into a climate model, and then can make accurate predictions.

What- what are you injecting differently into your cloud chamber when it's marine versus terrestrial?
