An Agenda for Land Data Assimilation Priorities: Realizing the Promise of Terrestrial Water, Energy, and Vegetation Observations From Space

The task of quantifying spatial and temporal variations in terrestrial water, energy, and vegetation conditions is challenging due to the significant complexity and heterogeneity of these conditions, all of which are impacted by climate change and anthropogenic activities. To address this challenge, Earth Observations (EOs) of the land and...

Water stress detection using radar

Vegetation is a crucial part of the water and carbon cycle. Through photosynthesis carbon is assimilated for biomass production, and oxygen is released into the atmosphere. During this process, water is transpired through the stomata, and is redistributed in the plant. Transpired water is refilled by uptake of water from the root zone in the...

Finding the Optimum Unsaturated Zone Storage Change Estimation Method to Improve Water Accounting in Vietnam

Evaluation of Two Automated Remote Sensing-Based Surface Energy Balance Models for Estimating Daily Evapotranspiration

Using remote sensed actual evaporation to improve hydrological models

In hydrological models evaporation is often still quite uncertain. Potential evaporation is used as input, but the modelling of plant stresses is not always accurate enough to describe the behaviour in reality. In situ measured actual evaporation data is rare, and doing measurements is time consuming and expensive. With the advance of satellite...

Regional vegetation water effects on satellite soil moisture estimations for West Africa

Soil moisture information is a vital parameter for water resources planning and food production. In particular for West Africa, where income largely depends on rainfed agriculture, reliable information on available soil water is required for modeling and prediction. Over large areas and, specifically, for data scarce regions, satellite soil...
