• Scientists from National Geographic Society and Tribhuvan University installed have installed two highest weather stations in the world in an expedition to Mount Everest that wrapped up in June 2019.
• The two weather monitoring stations are located at an altitude of 8,430 meters (27,657 feet) and 7,945 meters (26,066 feet). Also, three other stations have been set up across the Mount Everest.

BACKGROUND:

• The setting up of the weather station aim to collect weather data. The data gathered from the stations will help scientists to understand how rising global temperatures impacts the rapidly melting glaciers.
• The nearly two month expedition involved a team of more than 30 scientists from all over the world, including 17 Nepali researchers.
• The team also collected the world highest ice core sample at 8,020 meters , which will help the scientists study the deep record of precipitation on the mountain and composition of the atmosphere during pre-industrial times.
• The project also reached another milestone of placing the world’s highest helicopter-based lidar scan and the most detailed photogrammetric imaging, also with lidar scans, of the Everest Base Camp area and the entire Khumbu Glacier.
