Half-hourly meteorological forcing data from SACOL 2024 for offline CLM5.0 simulations of irrigated corn in semi-arid Loess Plateau

This dataset contains half-hourly meteorological observations from the Semiarid Climate and Environment Observatory of Lanzhou University (SACOL, 36°N, 104°E; elevation 1968 m) for the year 2024, used to drive offline point-scale simulations in CLM5.0. SACOL is a typical semi-arid site on the western Loess Plateau, with temperate semi-arid continental climate conditions. The observations include 2 m air temperature (TBOT), surface pressure (PSRF), relative humidity (RH), wind speed (WIND), precipitation (PRECTmms), downward shortwave radiation (FSDS), and downward longwave radiation (FLDS). All data have been quality-controlled, including outlier removal, short-term gap filling, and temporal consistency checks.
