Short summary
We constructed a monthly vector boundary dataset (2000–2024) for lakes ≥ 10 km² on the Tibetan Plateau using Google Earth Engine and MODIS data. A spectral-index random forest (93.21 % accuracy) and post-processing enhanced boundary precision. The dataset (TPLake-MED) shows steady lake expansion (~ 34.91 km2 yr−1) with peak area in September/October. Monthly changes are more significant in the west, and smaller lakes are more sensitive, offering insights for climate and ecosystem management.
