Jp2.2 Impact of Soil Moisture Initialization on Numerical Weather Forecasting over the Mississippi Delta Region
Soil moisture estimates are considered as a valuable input for various environment models including weather forecasting, water management, agriculture, and forestry applications. Generally, the network of soil moisture observations is not dense (typically only few observation points are available within each state) enough to meet the spatial resolution requirements of these applications. Theref...
متن کاملSetting Up a Sentinel 1 Based Soil Moisture - Data Assimilation System for Flash Flood Risk Mitigation
The objective of this research was to evaluate the potentialities of an advanced SM-DA system based on the assimilation of synthetic aperture radar (SAR) observations derived from Sentinel 1 (S1) acquisitions. A time-continuous, spatially-distributed, physically-based hydrological model was used: Continuum (Silvestro et al., 2013). The latter is currently exploited for civil protection activiti...
متن کاملFlash Flood Forecasting: An Ingredients-Based Methodology
An approach to forecasting the potential for flash flood–producing storms is developed, using the notion of basic ingredients. Heavy precipitation is the result of sustained high rainfall rates. In turn, high rainfall rates involve the rapid ascent of air containing substantial water vapor and also depend on the precipitation efficiency. The duration of an event is associated with its speed of ...
متن کاملHigh resolution soil moisture mapping
Soil moisture information is of critical importance to real-world applications such as agriculture, water resource management, flood, fire and landslide prediction, mobility, soil hydraulic parameter estimation etc. Many of these applications require soil moisture information at high resolution. While this may be estimated from land surface models, the predictions are often poor due to inadequa...
