Australia-centric animations

The following snapshots show MLD, salinity, and temperature from ACCESS-OM2 0.1 degrees.

The changes I have in mind are:

• center de camera to capture more of Antarctica within the same frame,
• add another light source on the left to avoid transitioning to black too quickly, and
• add some stars in the background.

Please let me know if you would like any other change, otherwise, I will upload a sample video in the next couple of days.

I also noticed that Navid's example has quite a glossy surface, which helps highlight the gradients.

This is a sample animation with the latest viridis colormap:

I like the Indian Ocean part of this. The EAC, though, has disappeared! Nemo is sad... 🐠🐡

there are distracting low-salinity flickers due to passing rainstorms... not sure what can be done about those - maybe a nonlinear colormap to de-emphasise the very low salinity?

[josuemtzmo]

I've tried different colormaps, here is one, but I hate it:

Therefore, I started playing more with the lighting and I used the gradients to further shade the image, I think this allows to see many more features, that previously were completly washed out:

For reference, here is the old version:

This middle panel is indeed better than the last one! Anyway, I'm pretty sure we'll never converge because it boils down to personal preference. @josuemtzmo do you like the middle one?! Don't you mind that you can't see the EAC? Or... perhaps... you see it? (your vision is much better than me, I know that).Or perhaps EAC is not there in the SSS any way?

Let's go with this version and move on with our lives?

So, I also am not a huge fan of the rainbows. Josué & I went for a bike ride at lunchtime today and discussed the following:

• Let's keep a cmocean colour scheme
• Let's use texture to get the right effect
• Let's also do some zooming down to regions, where we can better see the dynamics. So, I'm suggesting something like the middle option above to start, zooming into and look at a few currents, then switching to temperature and then zooming back out?

Thoughts?

I'm not fan of rainbows 🌈 (just to make this clear).

But I'm fan of flow features! :)

I think SSS is not so great for the EAC, I think SST will be much better, I will upload some stills using the same effect as the middle panel above. I think the idea of zooming in will make it easier to manipulate the contrast to highlight features, Just for the record, I will create them as different animations and files (See future comments in #6), so it will be simpler to reproduce any animation.

Who's going to be using this animation? I could imagine using something like this just to introduce that we have a model that is eddying, but maybe not much more than that? However zoomed out like this, you can't really interpret any of the dynamics in any particular region. I would add a vote for doing zoomed in versions of this instead (e.g. the EAC, a deeper layer near Antarctica, but probably both of those you want temperature not salinity).

@adele157 You are on the right track, although the animations will be scientifically accurate, my personal vision for these first animations will be to use them to introduce presentations and attract the attention of the audience, but not necessarily to describe specific processes. In order to describe specific processes, I need a more detailed storyboard to visualise the specific fields we want to describe (possibly pre-processing of data), rather than something general as the current animations.
