Turbulent flux and hydrometeorology observations in the high-altitude Naya Kanga catchment, Langtang, Nepal (Nov 2023 – Oct 2024)

Description High-altitude observations from four sites in the Naya Kanga subcathment in Langtang Valley in the Nepalese Himalaya. Data include observations from a flux tower (using a Campbell Scientific IRGASON), from a tipping bucket precipitation gauge, two small weather stations and three soil moisture pits. Data were acquired for the period between 8 November 2023 and 16 October 2024.
