NASA GLOBE Observer’s Weekly Roundup: 12-18 February 2017

Aerosols in our atmosphere both stop and aid cloud formation. Learn more about this and more in this week's roundup.

1. IMAGE OF THE WEEK: Which do you think is occurring in the image above: clouds forming or depleting? Find out which in the link below. You can also attend a colloquium concerning the topic -- mentioned further below.

2. COLLOQUIUM: NASA's Goddard Space Flight Center in Greenbelt, Maryland is hosting a colloquium titled: "Desert Dust, Wildfire Smoke, Volcanic Ash, Urban and Industrial Pollution - Grasping the Role Particles Play in Global Climate and Regional Air Quality." 

"Bright aerosols reflect sunlight, and can cool the surface; light-absorbing particles can heat the atmosphere, suppressing cloud formation or mediating larger-scale circulations. In most cases, particles are required to collect water vapor as the initial step in cloud formation, so their presence (or absence) and their hygroscopic or hydrophilic properties can affect cloud occurrence, structure, and ability to precipitate. " Read more in the below and learn how you can attend.

3. OBSERVATIONS:  Thank you again for taking the time to make cloud observations. Look for the update to the app coming in the next few weeks. One enhancement is that you will now have the opportunity to view what satellites saw at the time you made your observation. Stay up to date with new features and cloud science by checking this website and following us on Facebook and Twitter. 

4. PUBLIC SERVICE: Something that you can do, now that the rain has left puddles in some places, is to look over the areas you live and dump out any standing water. It doesn't take much time to do, and if we each take the time to do it we will help those we know and those we do not from the possibility of catching a mosquito-borne disease. Learn more about this campaign in GLOBE's mosquito larvae protocol. 

5. WEEKLY VIDEO: See last week's favorite cloud observation submissions from around the world on our Facebook page. And don't forget to share your favorite photos with us by tagging us on Facebook and Twitter: #NASAGO.
