Editorial statement
This paper presents a quality-controlled meteorological dataset from six automatic weather stations spanning almost 5,000 m of elevation in the Mount Everest region, from 3,810 to 8,810 m above sea level. The installation and maintenance required to gather this data presents and exceptional effort. These rare observations from some of the highest elevations on Earth provide a valuable resource for investigating high-altitude climate and weather, evaluating atmospheric models and reanalyses, and improving our understanding of the Himalayan climate system.

Short summary
We installed six automatic weather stations from 3,810 m to 8,810 m on Mount Everest region to better understand weather conditions at high altitudes. These measurements reveal how temperature, humidity, and wind changes with height and season. Our results show differences between observations and widely used ERA5 datasets. This improved knowledge helps scientists better understand mountain weather and climate, climate change and supports water resource planning for communities downstream.
