Hi Ms. Bergholz,


I have a few questions about what you are doing and what it's like in Antarctica.

How does working in such extreme weather conditions affect your ability to collect data? Are you on a schedual, and if so, is the weather permitting you to stick to it?

Also, how has this visit been going in comparison to your last visit? Has the data you have been calculating different or similar to the data that you calulated before?

 

I hope you have a wonderful holidy and rest of your trip,

Dear Anna from Marymount, If you go to the December 19 Journal, you can see exactly what it looks like here,  it is all flat around us with snow and the sky.
We can collect data even in cold weather. The only problem we have is if it is too windy and we can not fly the balloon. The team even flys balloons in the winter time when we have temperatures of minus 100 F! Yes, we are on  a schedule, but if it is too windy, we can not follow our schedule.
This trip has been very similar in terms of the work I am doing here: working with the Clean Air Group. I have added many more research aspects, such as the CFC's and CO2 that the group is monitoring.The data we have collected from the stratospheric balloon has been  very similar compared to the last time. We are seeing a decrease in the CFC's, though.
Have great holidays,
E. Bergholz
