Science AMAs are posted early to give readers a chance to ask questions and vote on the questions of others before the AMA starts.
Guests of /r/science have volunteered to answer questions; please treat them with due respect. Comment rules will be strictly enforced, and uncivil or rude behavior will result in a loss of privileges in /r/science.
If you have scientific expertise, please verify this with our moderators by getting your account flaired with the appropriate title.

How’s is what you’ve done different from past studies that have argued the ozone hole is recovering due to CFC bans (e.g. [Solomon 2016, *Science*](http://science.sciencemag.org/content/early/2016/06/30/science.aae0061))?
Why does the ozone layer have a hole at all, rather than just be thinner all around?
Here is the link to our NASA video: [https://www.nasa.gov/feature/goddard/2018/nasa\-study\-first\-direct\-proof\-of\-ozone\-hole\-recovery\-due\-to\-chemicals\-ban](https://www.nasa.gov/feature/goddard/2018/nasa-study-first-direct-proof-of-ozone-hole-recovery-due-to-chemicals-ban)
And a link to our journal article: [https://agupubs.onlinelibrary.wiley.com/doi/10.1002/2017GL074830](https://agupubs.onlinelibrary.wiley.com/doi/10.1002/2017GL074830)
What more can I do to help improve the condition of the ozone layer?
When can we expect the damage we have done to be completely recovered? And how do we prevent it from happening again?
This AMA is being permanently archived by *The Winnower*, a publishing platform that offers traditional scholarly publishing tools to traditional *and* non-traditional scholarly outputs—because scholarly communication doesn’t just happen in journals.

Is there anything someone can do around the home to help in preserving the atmosphere, or is it all up to badgering our leaders to enforce cleaner energy, manufacture, transport etc?
The Montreal Protocol is seen as a huge win for environmentalists. Was there as much widespread denial for ozone degradation as there is for climate change now?
Would further restoration of the ozone layer help reign in increasing temperatures on Earth?
What percentage has recovered?
How would you ELI5 the importance of the ozone to people who have never heard of it?
Has the ozone layer been permanently damaged by CFCs or can there be a full recovery eventually?
Did you learn anything surprising/unexpected?
What challenges did you face with setting up and executing the project?
What's it like working at a space flight center?
Are there any differences in other thin spots/holes in the ozone compared to the Antarctic's hole?
How does the process of access to the data to the data work and in what form do you get the data? Do you need to wade through a database for the relevant tables? Is the satellite set up to send specific information for your specific study? Do you specify what data set you need and somebody set up a database for you?
Do you have to go to Antarctica to collect some of your data? If so what sort of challenges do you face as a result of this? I imagine that sort of environment could be quite harsh on scientific equipment and scientists alike.
