2026-07-08 A dataset of meteorological observations at Huitong National Research Station of Forest Ecosystem in Hunan (2005–2024) doi:10.57760/sciencedb.j00001.01798 en  Mid‑subtropical evergreen broad‑leaved forest is a major forest type in China, playing a crucial role in the global carbon cycle, biodiversity maintenance, and regional climate regulation. Long‑term, high‑precision local meteorological observation data are essential for understanding the structure and function of this forest ecosystem and for assessing its response and adaptation to global change. Huitong National Research Station of Forest Ecosystem (Huitong Station) is located in the core distribution area of typical mid‑subtropical evergreen broad‑leaved forest. Since 2005, the station has conducted long‑term continuous monitoring of multiple meteorological elements using an automatic weather observation system at its meteorological observation field. This dataset compiles 20 years of meteorological observations from 2005 to 2024, including monthly statistical data for 14 key meteorological variables: air temperature, relative humidity, air pressure, precipitation, 10‑minute average wind speed, surface temperature, soil temperature at depths of 5, 10, 15, 20, 40, 60 and 100 cm, and solar radiation. The dataset consists of 13 data sheets with a total data volume of approximately 130 KB. The establishment of this dataset aims to provide reliable foundational data for research on ecosystem processes, biodiversity conservation, forest hydrological effects, and climate change response in mid‑subtropical evergreen broad‑leaved forests, thereby supporting regional ecological security assessments and national ecological civilization construction.
