How satellites measuring soil moisture provide a new understanding of rainfall patterns

Luca Brocca, Luca Ciabatta, Christian Massari, Stefania Camici, Paolo Filippucci February 24, 2020

Soil moisture and rainfall are the two fundamental variables in the water and energy cycle and their knowledge in many applications is crucial. For instance, for predicting the occurrence and the magnitude of flood and landslide events the knowledge of the initial soil moisture condition and of rainfall amount is mandatory. In the last decade, some authors have proposed a completely new approach, ...[Read More]

Imaggeo on Mondays: The Tempest

Hazel Gibson February 24, 2020

Measuring the aurora. This picture was taken while doing an optical/radar coordinated campaign in Svalbard, Norway, near the settlement of Longyearbyen. In this campaign, we were measuring for the first time the polarisation of the auroral ‘red line’ of atomic oxygen with a photopolarimeter and were running the radars in order to have a better understanding of the state of the ionosphe ...[Read More]

The foot of a glaciated mammoth? No… A glacier!

Marie Cavitte February 21, 2020

Ice is a viscous fluid: it flows but slowly, reaching up to 100 m/yr for the fastest flowing ice. That’s 0.00001 km/hr, so you’d never see it with the naked eye. But what influences the morphology of the glaciers is the shape of the topography that lies underneath them. Elephant Foot Glacier, shown above, aptly named for its shape, is a textbook-example of a piedmont glacier. These types of glacie ...[Read More]

The Sassy Scientist – Climate Change Causality

The Sassy Scientist February 21, 2020

Tom Doehne has been watching the news reports on the effects of climate change on human civilization. Dumbfounded that the main stream has not peered beyond the variable intensity of weather patterns and the mere notion of rising sea levels, he pondered: Will the increase in ocean level trigger more slippage along subduction zones? Dear Tom, In terms of geophysical research angles this really is a ...[Read More]

Featured catchment series: The San Carlos Catchment in northeast Costa Rica, a multi-scale hydrological observatory to leapfrog data scarcity in the tropics

EGU Guest blogger February 19, 2020

Tropical ecosystems are of major hydrological importance for regional and global climate systems and are characterized by greater energy inputs, higher rate of change and dynamics compared to other hydroclimatic regions. Nowadays, the anthropogenic influence in the climate crisis exerts enormous pressure on tropical hydrological systems. This growing pressure affects water quality and quantity, wh ...[Read More]

Science. Exploration. Survival.

Editorial team 1 February 19, 2020

A scientific career can be a struggle. This week Dave Stegman, Associate Professor at Scripps, draws parallels between being a scientist and being an Antarctic explorer. He dangled in the crevasse, unable to touch the sides; the abyss beneath was hundreds of feet deep; the rope he was suspended from was 14 feet long, connected above to the sledge he had been hauling. Was it luck when his sledge ha ...[Read More]

Ambient seismic noise and the quest for groundwater

Marina Corradini February 18, 2020

Groundwater is water stored within permeable geological formations, and nearly a third of Earth’s freshwater supply comes from this source (a). In Africa, the overwhelming majority of distributable freshwater is contained in groundwater, and in the EU, 75% of the population relies on groundwater (b). This dependence on groundwater is steadily rising. As humanity as a whole, figures out how ...[Read More]
