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.




Bill Smith, left, along with Kris Bedka. The NASA GLOBE Clouds team is excited to share with you this recent news article about two NASA scientists that help match your observations with satellite data - Bill Smith and Kris Bedka. They, along with Louis Nguyen lead SatCORPS, at team at NASA Langley Research Center that use expertise in clouds to make better weather predictions.  Read more about their work at  https://www.nasa.gov/feature/langley/how-cloud-data-is-improving-weather-forecasts

We are excited to have such a response to the NASA GLOBE Clouds: Spring Cloud Observations Data Challenge .  Remember, top observers will be congratulated by a NASA scientist! Click here to learn more about the challenge.  Are you wondering about the clouds you are reporting and the type of weather you might experience in your area? Here is a guide to how cloud types are related to weather!  The information below was taken from the NOAA's SciJinks webpage -  https://scijinks.gov/clouds/

Today we start a series of posts devoted to providing information, tips, tricks and answers to frequently asked questions by Calitoo users! So, how do you measure Aerosol Optical Thickness (AOT) with a Calitoo? First and foremost: NEVER look directly at the sun! And… ONLY take measurements when the sun is not obstructed by clouds. TIP: Use your hand(s) to cover the sun; if you see any clouds on either side of your hand(s), do NOT take any measurements. Wait until the sun is not obstructed by clouds. Now, the Calitoo sun photometer measures AOT values at 465 nm, 540...

The NASA GLOBE Clouds team is excited to highlight Mr. Gary Popiolkowski, a middle school science teacher at Chartiers-Houston Jr./Sr. High School in Houston, PA, USA. Mr. Popiolkowski has been teaching for 44 years and has been a GLOBE teacher since 1995. He has had his students doing cloud observations for the past 18 years, submitting over 15,000 observations! He has also been doing virtual connections with Patumwan Demonstration School in Thailand each year for the past four years. We ask Mr. Popiolkowski how he does it! Here is what he shared: Each period of the day the...

A fourth grade student from Public School 122 (Queens, NY), recently visited NASA Langley for a week. During his visit, he studied the GLOBE Aerosol Protocol. He went outside the Atmospheric Sciences building and collected aerosol data using a Calitoo sun photometer, which measures Aerosol Optical Thickness (AOT) at three wavelengths: 465nm (blue), 540nm (green) and 619nm (red). After downloading the data measured with the Calitoo to his laptop, the student learned how to access AERONET data. The AERONET ( AE rosol RO botic NET work) project is a federation of ground-based remote...
