Special Issue Information

Dear Colleagues,

Soil moisture is a key parameter when it comes to understanding the processes related to the water cycle on continental surfaces (infiltration, evapotranspiration, runoff, etc.). It plays a major role in the management of irrigation and the monitoring of extreme events (floods, drought, etc.).

Soil moisture monitoring has advanced in recent years, creating opportunities to transform scientific understanding of soil moisture and related processes. Over the past several decades, great progress has been made in soil moisture monitoring. These include emerging in situ and proximal sensing techniques, dedicated soil moisture remote sensing missions, as well as soil moisture monitoring networks. In addition, the assimilation of soil moisture data for meteorological or hydrologic forecasting also shows promise.

Here, we invite you to publish works that present the use of any method (satellite and aerial RS, UAV, field robot, sensors, and simulation) for assessment of soil moisture. Works devoted to the broadly understood modelling and mapping of soil moisture are also welcome.

The topics of the Special Issue include, but are not limited to, the following:

  • Review on soil moisture monitoring;
  • Introduction to field, aircraft experiments, or satellite missions for soil moisture;
  • Development, calibration, or validation of the theoretical or semi-empirical models used for soil moisture monitoring;
  • Development, improvement, or comparison soil moisture monitoring algorithms;
  • Evaluation or comparison of soil moisture mapping in situ measurements, model simulations, or other mathematical approaches;
  • Application of soil moisture in data assimilation, agriculture, ecology, hydrology, climate change, and other fields;
  • Temporal approach to soil moisture monitoring;
  • New soil moisture monitoring technology methods, such as machine and deep learning.

Soil moisture (SM) plays an important role in regulating terrestrial–atmospheric water circulation and energy balance. Most of the existing studies have explored the dynamic patterns of SM based on experimental methods. However, the analysis of large-scale regions and long-term SM sequences was limited. Alternatively, satellite remote sensing data is a potential source for SM analysis for large-scale basins. Therefore, the SM data from the European Space Agency (ESA) Climate Change Initiative (CCI) from 2000 to 2015 is used in this paper to analyze the SM spatial-temporal changes in the Yellow River Basin (YRB). Further, the Normalized Difference Vegetation Index (NDVI) and meteorological data are used to explore the relationships between SM and NDVI, precipitation, air temperature, and wind speed, respectively. The results showed that the overall trend of SM in the YRB was decreasing from southeast to northwest during the past 16 years. The upper reaches of the YRB had shown a humid trend, with a value of 0.00047 m3·m−3·year−1, mainly due to the increase in precipitation; there was an obvious drought trend in the middle reaches of the YRB, especially in Shanxi Province and Henan Province, with a value of −0.00030 m3·m−3·year−1, which may be owed to vegetation greening increasing the soil evaporation. Overall, it is determined that the main factors influencing SM changes were NDVI and precipitation, followed by air temperature and wind speed. This study can provide a scientific basis for the spatial-temporal distribution characteristics and attributions of SM in the YRB over a long time series. Full article
