At 3:30 pm on 6 April, an EGU webinar will explain what will be offered during the upcoming #shareEGU20 virtual conference and how everyone can get involved – for free!
A new, high-resolution mapping framework will enable accurate forecasts of crop water use, according to research published in the EGU journal Hydrology and Earth System Sciences.
The EGU will instead host a week-long series of online activities the first week of May that support our community by fostering scientific communication.
The European Geosciences Union (EGU) and its partner Copernicus are announcing the launch of EGUsphere, a new online platform designed to increase visibility and boost discussion and collaboration within the Earth, planetary and space science community.
The EGU invites applications for the Union’s new programme of grants designed to fund the preparation of higher education (university-level) geoscience teaching packages. The deadline is 1 June 2020.
The Nimbus 7 limb infrared monitor of the stratosphere (LIMS) instrument operated from October 25, 1978, through May 28, 1979. This note focuses on the lower stratosphere of the southern hemisphere, subpolar regions in relation to the position of the polar vortex. Both LIMS ozone and nitric acid show reductions within the edge of the polar vortex at 46 hPa near 60° S from late October through mid-November 1978, indicating that there was a chemical loss of Antarctic ozone some weeks earlier.
We investigate the changes in natural methane emissions between the Last Glacial Maximum and preindustrial periods with a methane-enabled version of MPI-ESM. We consider all natural sources of methane except for emissions from wild animals and geological sources. Changes are dominated by changes in tropical wetland emissions, high-latitude wetlands play a secondary role, and all other natural sources are of minor importance. We explain the changes in ice core methane by methane emissions only.
We demonstrate for the first time that large festivals can be significant methane sources, though they are not included in emission inventories. We combined in situ measurements with a Gaussian plume model to determine the Oktoberfest emissions and show that they are not due solely to human biogenic emissions, but are instead primarily fossil fuel related. Our study provides the foundation to develop reduction policies for such events and new pathways to mitigate fossil fuel methane emissions.
Cloud water content and the number of droplets inside clouds covary with boundary layer depth. This covariation may amplify the change in water content due to a change in droplet number inferred from long-term observations. Taking this into account shows that the change in water content for increased droplet number in observations and high-resolution simulations agrees in shallow boundary layers. Meanwhile, deep boundary layers are under-sampled in process-scale simulations and observations.
Each month, Jesse Zondervan picks his favourite posts from geoscience and development blogs/news which cover the geology for global development interest. Here’s a round-up of Jesse’s favourite selections for the first three months of 2020: [Editor’s note: This post reflects Jesse’s personal opinions. These opinions may not reflect official policy positions of Geology for Global Development.] For many people, their news feeds consist of largely coronavirus updates. Not surprisingly, global development news is also overwhelmed with responses to the current …
The COVID-19 pandemic has brought us somewhere new. With many of us confined to our homes, the Seismology ECS representatives launch a new blog series, where they put together articles, reflections, and stories to accompany the community through this unprecedented historic period.
