High-altitude research involves studying the atmosphere and environmental conditions at high elevations, typically above 2,500 meters (8,200 feet). Scientists conduct experiments to understand how factors like temperature, pressure, and radiation change with altitude. This research is crucial for fields such as meteorology, climate science, and aerospace engineering. Researchers often use specialized equipment, including weather balloons and aircraft, to collect data in these challenging environments. High-altitude research also helps improve our understanding of climate change and its effects on ecosystems, as well as the health impacts of reduced oxygen levels on humans and animals.
