The dataset contains the continuous daily lake surface temperature of 160 Lakes (with an area of more than 40km2) in the Tibetan Plateau from 1978 to 2017. Firstly, an semi-physical lake model (air2water) based on energy balance was improved to realize the continuous simulation of lake surface temperature even during ice age. The impoved model was calibrated by lake surface temperature from MOD11A1 product. The correlation between the dataset and in-situ lake surface temperature of four lakes is higher than 0.9, and the root mean square errors are less than 2.5 ℃. The data set provides data support for understanding the water and heat balance , the process of aquatic ecosystem and its response to climate change of lakes in the Tibetan Plateau.

File naming and required software

The dataset contains 160 CSV file for each lake. The CSV file named as "TPxxx.csv": xxx is the lake ID in 'lake_info.csv'. Each CSV file have 7 columns:
i) year; ii) month; iii)) day; iv) LSWT derived from MOD11A1 daytime products (℃); v) LSWT derived from MOD11A1 nighttime products (℃); vi) mean of MOD11A1_DT and MOD11A1_NT, which is used for calibration and validation (℃); vii) model-based daily lake surface water temperature (℃).
