Good explanation of what you saw last night...for us this far South, we see a lot of the reddish pink because at our latitude, we see the upper altitude mostly. We in the South experienced something very unique and possibly once in a lifetime for those that were curious...

Wow!
Also, 2005 was 19 years ago?!?!

Thank you for your very lovely visit & inspiring #LeeLecture , Dr. Joe Francisco of Penn Chemistry. We're going to work on cloud chemistry.

Dr. Cusworth was our last speaker at the atmospheric Chemistry GRC and his talk was FABULOUS. Great science conveyed with such enthusiasm... you should go if you can.

Lot's of low level ☁️☁️ over the Midwest. It's hard to make clouds w/o particles & it's hard to make particles w/o ammonia. U.S. EPA will tell you #livestock is the largest source of ammonia & there's lots of animals in these parts. #agriculture #AirQuality

You breathe in ~11,000 liters of air every day. What's in your air? #AirQuality

Thanks for visiting us, Arthur!

Prominent Universities have a responsibility to help future leaders understand & root out antisemitism, Islamophobia, sexism & other forms of extremism. Enlightened leaders listen to the hard things & confront difficult conversations head-on. I wish I was seeing more of that.

Happy Earth Day....ice clouds over Iceland. We live in a gorgeous world...let's take better care of it!!!!

With sadness I would like to share that Joan Rowland passed away. She was a treasure and meeting her was a privilege.

Need a timeline cleanse?
Lots of #biodiversity on this Georgia island

All these years later, I still vividly remember the failure probability calculations for bridges on my PE exam. What a nightmare for those poor people 💔
Engineers will learn from this & then #Nevermore

Congratulations MethaneSAT on a successful launch! An exciting moment! Very much looking forward to its impact on the climate and air quality community
