Code and data for the paper: Cooling effects of local and surrounding greening across the urban-rural gradient

Cooling effects of local and surrounding greening across the urban-rural gradient This package contains processed data and R code for the study of urban greening and summer land surface temperature in Zhengzhou, China. | File | Contents || `Grid_panel_300_main_calculate.csv` | 300 m grid panel for the main analysis || `Grid_panel_500_robustness_analysis.csv` | 500 m grid panel for the spatial-resolution robustness check || `ZZ_*_LULC_clip.tif` | 10 m land-cover maps for 2003, 2010, 2017 and 2024. Classes 0–4 are water, impervious surface, green space, bare land and farmland. NoData is 15. || `zz_300_clip.*` and `zz_500_clip.*` | Grid geometries. Keep each set of shapefile components together and join by `Grid_ID`. || `data_calculate_relative_paths.R` | Fixed-effects models, marginal effects and greening scenarios | The panels use `Grid_ID` and `period` as the joint key. Period codes 310, 1017 and 1724 denote 2003–2010, 2010–2017 and 2017–2024. `dG` and `W_dG` are local and surrounding greening changes in percentage points. `P1_t0` is baseline impervious surface cover in percent. Negative LST changes indicate cooling.
