Thirteen‑year open‑top‑chamber gradient warming experiment in an alpine meadow on the Qinghai‑Tibet Plateau: soil carbon fractions, plant community, microbial biomarkers and extracellular enzyme data

Dataset containing soil organic carbon fractions (POC, MAOC), plant biomass and diversity, PLFA microbial community, amino‑sugar‑based microbial necromass carbon, extracellular enzyme activities, soil physicochemical properties from a 13‑year OTC gradient soil‑warming experiment at Haibei alpine meadow station (Qinghai‑Tibet Plateau, China). The experiment includes five temperature levels (ambient to +1.88 °C soil warming), n = 25 plots.
