STEM Professionals' Blog


The GLOBE International STEM professionals Network (GISN) Blog is an online collaborative effort where scientists associated with GLOBE post their thoughts, comments, and philosophies about a variety of science topics.

GLOBE strongly encourages positive and productive discussions to further advance the scientific understanding of all involved with The GLOBE Program.




  The 2019 GLOBE International Virtual Science Symposium important dates and rubrics are now available! The GLOBE Clouds team at NASA Langley Research Center would love to see you use cloud observations in your research!  Do you need some ideas? Here are a few. Also, don't forget about the blog on how to come up with a good research question .  K-2nd grade: - What is the cloud type observed the most during Fall/Spring/Summer (choose one or a different period of time)? - Which cloud type, nimbostratus or cumulonimbus, produces the most...

CloudSat and CALIPSO were designed to complement each other in the 1990s. They launched together on the same rocket in 2006. Then they spent more than 10 years orbiting Earth in formation with a coterie of other satellites in what's known as the A-Train, or afternoon constellation.  Flying together enables the A Train satellites to gather diverse measurements of the Earth below at nearly the same time as they circle the globe pole-to-pole, crossing the equator around 1:30 p.m. local time every day. The nearly simultaneous observations allow scientists to build a more...

Our mosquito story is a climate story. In the Early Holocene around 8200 years ago, the area that is today the Sahara Desert was much wetter and supported grassland vegetation. During the mid-Holocene, about 5000 years ago, changes in the monsoon began to dry out much of north Africa. This caused the Sahara to expand, and the yellow fever mosquito ( Aedes aegypti) was forced to retreat to areas where they could still find standing water to breed. These were also the same places where humans migrated, congregated and settled. A changing climate brought people and mosquitoes together, and...

Whenever you submit a cloud observations, the GLOBE Clouds team at NASA Langley Research Center looks for satellites that were over your area at about the same time. The team then gathers the information from these satellites and compares them to your own observations. The result is a satellite match table that you receive through an email!    The table allows you to compare what you saw and what the satellite noted. You also have the actual satellite image at the bottom of the table! A new "How to Read a Satellite Match"  page is available for you to learn...

It’s that time of the year again! In the Northern Hemisphere, the chlorophyll in leaves are breaking down causing the green in leaves to disappear and allowing for orange and yellow colors to become visible. At GLOBE, we call this process Green-Down , and if you have not started collecting your Green-Down data yet, it's not too late*! *If you are in the U.S., you can track the annual progressive changing of the leaves with this Fall Foliage Prediction Map from Smokey Mountains.
