TY - Data T1 - Shiyang River Basin 1-kilometer resolution total annual surface evapotranspiration data set (2001-2020) A1 - Jia Li A1 - Hu Guangcheng DO - 10.12072/ncdc.nieer.db3921.2023 PY - 2023 DA - 2023-08-23 PB - National Cryosphere Desert Data Center AB - This data is the annual total surface evapotranspiration (ET) data for the Shiyang River Basin from 2001 to 2020, with a spatial resolution of 1 kilometer. This data product is generated by using the ETMonitor model and combining multi-source remote sensing data and reanalysis data. In the process of data production, the daily scale ET is firstly calculated, and then accumulated to get the annual total ET. The ETMonitor remote sensing ET model is based on the mechanism model of energy balance, water balance and plant physiological process, etc. The unit of ET is mm per year. The ET unit is millimeters per year and the conversion factor is 0.01. DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/8a188c3f-e6c4-42aa-b5ed-9fa2a91cb619 ER -
