| Title: | Main Title: Evaluation of the cosmic ray soil moisture method correcting for remotely sensed biomass estimates |
| Description: | Abstract: Soil water content is a key variable in the global hydrological cycle. Important hydrological processes 25 such as evapotranspiration can be controlled by root zone water content if evapotranspiration is water 26 limited. This is in general the case in (semi-)arid environments and in the temperate regions during 27 summer time. Agricultural production can be limited by soil water content availability. This raises the 28 need for irrigation in large parts of the world to sustain food supply. Climate and weather conditions are 29 influenced by mass and energy fluxes between the land surface and the atmosphere. Under drought 30 conditions, evapotranspiration from the land surface increases compared to normal climatic conditions 31 (Dirmeyer and Brubaker, 1999).Furthermore, surface and sub-surface runoff generation depends largely 32 on the degree of soil saturation and soil hydraulic properties. To better understand hydrologic processes 33 on relevant scales, soil water content estimates are commonly a key component of hydrological (Brocca 34 et al., 2012), land surface and climate models (Koster et al., 2004). Recent publications (Vereecken et al., 35 2008) emphasize the need for soil water content measurements at the field scale to estimate process 36 variables and parameters. However, high spatial variability and temporal dynamics of soil water content 37 pose a challenge for soil water content measurements at relevant scales. |
