The NASA-sponsored Global Learning and Observations to Benefit the Environment (GLOBE) Program has received the American Geophysical Union (AGU) 2021 Excellence in Earth and Space Science Education Award. According to AGU, the annual award honors an individual, group, or team committed to promoting excellent geophysical education.
Through GLOBE, people around the world learn how to document and share useful information about their local environment with scientists. Launched on Earth Day in 1995, GLOBE connects scientists, teachers, and students in 126 countries with hands-on scientific activities.
“GLOBE is a phenomenal program that has a special place at NASA,” said Dr. Allison Leidner, program manager for education and communication in the Earth Science Division of NASA’s Science Mission Directorate. “Enabling students and citizen scientists to investigate our home planet gives them a greater appreciation of our environment, ignites their interest in science-related careers, and connects them to the international Earth science community. We are so happy to see AGU recognize GLOBE with this award.”
Through teachers that have been trained in GLOBE protocols, students learn how to conduct scientific investigations and collect data in their community. GLOBE science protocols were developed with Earth scientists and many protocols have connections to NASA’s satellite missions. So far, GLOBE participants have gathered and shared more than 200 million Earth science observations.
“The GLOBE Program has made outstanding achievements and contributions by pushing the frontiers of our science forward,” said AGU President Susan Lozier in a statement, on behalf of the AGU Earth and space science community. “GLOBE has also embodied AGU’s shared vision of a thriving, sustainable and equitable future for all, powered by discovery, innovation, and action. And you did this with integrity, respect, diversity, and collaboration while creating deep engagement in education and outreach.”
In addition to being sponsored by NASA, GLOBE is supported by the National Science Foundation (NSF), National Oceanic and Atmospheric Administration (NOAA), and the U.S. Department of State.
Dr. Tony Murphy, GLOBE Implementation Office director, and Dr. Caryn Long, middle school science teacher at Montverde Academy (Florida), share more about the program and its recent recognition. Their responses have been edited for clarity.
Tony Murphy: GLOBE has a strong community of citizen scientists, students, and teachers all over the world who are eager to contribute to Earth system science research. GLOBE allows people to contribute to data collection and submission, to understand the scientific research process and the work of scientists, and to see how their local environment fits into the regional and global environment.
Caryn Long: I have used GLOBE in my classroom for five years now. GLOBE is different from other science education programs because it educates students while also immersing them in the practical and applied nature of science. Knowing they are contributing to real research with NASA scientists is a powerful motivational tool to get them to practice the skills of observation, data collection, and analysis in a real and meaningful way. They want to practice the skills they are developing because what they are doing is valued.
Long: Our classroom participates in the Cloud, Aerosols and Hydrology Protocols and the Surface Temperature Field Campaign at the lake behind our school. We are adding more protocols each year. Each time I share with my students that we are learning a new protocol to add to their toolbox, they are excited to get started. What my students have enjoyed most about GLOBE is meeting some of the scientists that are involved with the program. Another highlight for them is gathering the cloud data because it involves NASA satellites. Receiving the email matches with the satellites is exciting to the kids because they love comparing what they saw from a ground level to what the satellite has viewed.
Murphy: Seeing students communicate their research at meetings, and especially at the two GLOBE Learning Expeditions I have attended, has been truly amazing. GLOBE Learning Expeditions are week-long, student-focused events held every few years at sites around the world. I gave a scientific presentation at a national science competition in Ireland when I was in middle school. That experience had a major influence on my life, so it’s incredible to see so many GLOBE participants have a similar opportunity.
Murphy: The GLOBE community has grown tremendously from a small number of countries in 1995 to 126 countries today with a database of over 200 million measurements for use in research by students and scientists. New technology advancements including the GLOBE Program’s app, GLOBE Observer, have impacted the ways in which the program is implemented and enables citizen scientists to participate. The GLOBE community worldwide, including students, country coordinators, teachers, program support staff, government officials, and program sponsors, have allowed GLOBE to earn this recognition.
Who knew that being a scientist could be as easy as pointing your phone at the sky? This month, NASA and the GLOBE Program are asking citizen scientists to take out their phones and report what kinds of clouds they see above them.
From October 15 to November 15 citizen scientists young, old, and in-between can submit up to ten cloud observations per day using the GLOBE Observer app or one of GLOBE’s other data entry options (for trained members). Participants with the most observations will receive a personalized thank you from a NASA scientist.
“What excites researchers about GLOBE observations is the ability to see what’s up in the sky from volunteers’ perspectives all over the world,” said Marilé Colón Robles, lead for the GLOBE Clouds Team at NASA’s Langley Research Center. “What our eyes can see is difficult to fully duplicate with instruments. Merging these views is what makes a complete and impactful story.”
“We want to do a data challenge in the fall and see if there are any differences from what was observed during the spring data challenge of 2018,” said Colón Robles. “From thin, high clouds that are hard for satellites to detect to dust storms that impact our daily lives, these observations play an important role in better understanding our atmosphere.”
At NASA, scientists work with a suite of satellite instruments known as the Clouds and the Earth’s Radiant Energy System (CERES). Though they have these highly sensitive instruments, it can sometimes be difficult for scientists to distinguish features such as cirrus clouds from snow cover in their imagery because both are cold and bright from a satellite perspective. By comparing satellite images from a particular area with data submitted by citizen scientists, researchers can differentiate between the two.
Lucky GLOBE observers might make an observation while the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) is overhead. CALIPSO is a joint mission between NASA and the French space agency (CNES) that uses laser pulses to measure clouds and atmospheric aerosols. Citizen scientists who make observations at the same time and place as CALIPSO will receive an emailed satellite comparison of CALIPSO’s measurements showing features such as high clouds, dust, and smoke. Scientists are especially interested in these observations in order to improve their understanding of dust storms. During the challenge, make sure you turn on daily satellite notifications in the app or use this satellite overpass website to see the schedule for your location.
“Last year’s challenge gave researchers special glimpses into cloud types around the world,” said Colón Robles. “Photographs provided by observers gave insight into events such as dust storms and wildfires. Our hope is to once again learn from the community and together study our atmosphere.”
The 2018 data challenge, which took place in the spring, received more than 56,000 cloud observations from more than 15,000 locations in 99 countries and Antarctica.
NASA is a sponsor of GLOBE, an international science and education program that provides students and the public with the opportunity to participate in data collection and the scientific process. NASA GLOBE Observer is a free smartphone app that lets anyone make citizen science observations from the palm of their hand.
