| Abstract: |
| Evapotranspiration (ET) has changed greatly across the world in the past decades. There are various drivers that may affect the changes in ET. Understanding the changes in ET and the potential drivers is of great importance to water resources management in the arid regions. In this study, we attempt to show the trend in ET using satellite-based data in the Asian arid and regions from 2003 to 2017. Trends in different ET components, i.e., the evaporation from bare soil and transpiration from vegetation, are also shown to analysis the respective contribution to changes in ET. The results show that the evaporation from bare soil is the main component of ET and contributed larger to the changes in ET from 2003 to 2017. This analysis provides useful information for water resources management and planning with respect to forest and agricultural development in the Asian arid regions. Further investigation is needed for a better understanding of the drivers of the changes in ET. |
