GLOBO

Globo: A High-Altitude Balloon for Environmental Monitoring and Climate Research

Similar projects worth following
Rising greenhouse gases like CO₂ and methane drive global warming, making accurate, real-time data crucial for identifying high-risk areas and developing solutions. High-altitude CubeSats offer a sustainable and scalable way to monitor greenhouse gases and atmospheric conditions, filling gaps left by ground-based systems and informing climate action strategies.

Our CS 12 team is designing and deploying GLOBO, a high-altitude CubeSat equipped with sensors to monitor humidity, temperature, CO₂ levels, methane, and pollutants, alongside visual observations. The prototype includes GPS tracking, a robust communication system, and a 3D-printed payload frame to ensure reliability in challenging conditions.

The project demonstrates the potential of high-altitude balloons in advancing climate research. By addressing gaps in pollution tracking and its environmental impacts, GLOBO provides insights into local pollution trends, their sources, and effects on climate change.

    We are so excited to share that we have been granted money from the Housner Fund to complete our project. This will allow us to purchase the parts that we need to make this project a reality. We are grateful for the support, and are excited about the future of this project. 

  • Successful Integration of Clock, Sensor, and SD Card Reader

    Stephanie Wallen02/05/2025 at 18:16 0 comments

    Using the Arduino Uno we successfully integrated the clock, sensor, and SD card reader. The real time clock will allow us to keep track of when measurements are being recorded. The sensor, a BME 688, allows us to get measurements like humidity, temperature, and altitude. Finally, the SD card will allow us to transfer this data back to our computer. Attached is the photo with our weather readings and their corresponding time stamp. 

  • Successful SD Card Data Upload

    Stephanie Wallen02/03/2025 at 07:06 0 comments

    We successfully transferred data from the Arduino onto the SD card and opened the data using an SD card reader on another computer. We also successfully uploaded the data from the sensor onto the SD card. 

  • Parallel Circuit

    The primary purpose of this project is to create a functional prototype that demonstrates how high-altitude balloons can be leveraged for environmental monitoring and climate research. By equipping our high altitude balloon with sensors for CO₂, aerosols, and infrared temperature variations, we aim to address critical gaps in pollution tracking and its environmental effects.   To make this project a reality we need funding. Our anticipated budget is less than $1,000, since we have a simple one unit payload design. In comparison, other high altitude balloons usually cost over $5,000. We have applied to the George W. Housner Student Discovery Fund to hopefully get the financial resources we need for this project.

  • Project Objective

    Stephanie Wallen01/31/2025 at 04:41 0 comments

    With rising levels of greenhouse gases like CO₂ and methane driving global warming, obtaining real-time, accurate data on these emissions is essential to pinpoint high-risk areas and develop effective solutions. Particularly, in light of recent fires, studies of atmospheric emission footprints are essential to environmental research efforts.

    High-altitude CubeSats are a sustainable, cost-effective, and scalable way to monitor greenhouse gases and monitor atmospheric conditions. By deploying advanced sensors in the upper atmosphere, CubeSats continuously gather data in real time, filling the gaps left by ground-based monitoring systems. These important insights can inform policy decisions, improve environmental management, and enable more targeted actions to combat climate change. Thus, greenhouse gas and environmental monitoring high-altitude CubeSats are crucial for addressing the growing challenges of climate change and environmental degradation. Inspired by this growing need, we aim to design, prototype, and deploy a high altitude CubeSat GLOBO equipped with advanced sensors for monitoring atmospheric conditions and pollutants.  

    Our project entails the design and deployment of a high-altitude balloon prototype equipped with an array of environmental sensors for comprehensive atmospheric data collection and transmission.
