Dynamics of Nocturnal Evapotranspiration in a Dry Region of the Chinese Loess Plateau: A Multi-Timescale Analysis
Published 2025-07-01“…The results showed the following: (1) In contrast to the non-significant trend in <i>ETN</i> on the diurnal and daily scales, monthly <i>ETN</i> dynamics exhibited two peak fluctuations during the growing season. (2) The contribution of <i>ETN</i> to <i>ET</i> exhibited seasonal characteristics, being relatively low in summer, with interannual variations ranging from 10.9% to 14.3% and an annual average of 12.8%. (3) The half-hourly <i>ETN</i>, determined by machine learning methods, was driven by a combination of factors. …”
