<p dir="ltr">C-LDTR HRv1 is a high-resolution version of the China global Land Diurnal Temperature Range (C-LDTR) (available at https://doi.org/10.6084/m9.figshare.28030196.v2). The data are divided into two parts: climatology (1961–1990 average) and anomaly. Based on C-LSAT 2.1 station data, we used the Thin Plate Spline method to interpolate the climatology field and the Adjusted Inverse Distance Weighted method to interpolate the anomaly field. Temporal coverage: 1901-2023. Spatial resolution: 0.5° x 0.5°.</p>
