Improving Hydrological Predictions Of Land System Models

By: Thibault Hallouin Given the existence of feedbacks between the Earth’s atmosphere and the Earth’s surface, hydrological knowledge (e.g. soil moisture and open water available for evaporation and plant transpiration) is as critical to atmospheric scientists, as meteorological knowledge is … Continue reading

Improving forecasting of flooding from intense rainfall through interdisciplinary research

By: Linda Speight In England and Wales alone 3 million properties are at risk of surface water flooding. Having spent the past year speaking to a number of experts in the field (see below), I feel confident saying the universal … Continue reading

A simple way to find out where the moisture for regional rainfall comes from

by Liang Guo Moisture tracing is an interesting scientific topic that has fascinated meteorologists and hydrologists for decades. Methods for tracing moisture are numerous, from observations to numerical modelling, from water isotopes to remote sensing, from online tracking to off-line … Continue reading

Soil Moisture retrieval from satellite SAR imagery

By Keith Morrison Soil moisture retrieval from satellite synthetic aperture radar (SAR) imagery uses the knowledge that the signal reflected from a soil is related to its dielectric properties. For a given soil type, variations in dielectric are controlled solely … Continue reading
