EGU’s response to potential changes to the European Research Council

  • EGU news
  • 11 February 2019

A scheduled re-organisation of the European Commission’s Research and Innovation Directorate General has raised concerns about its potential impact on the European Research Council (ERC). The EGU strongly supports the unique ability that the ERC currently has to respond directly and independently to the needs of the scientific community.

Evaluation of CloudSat snowfall rate profiles by a comparison with in situ micro-rain radar observations in East Antarctica

Evaluation of the vertical precipitation rate profiles of CloudSat radar by comparison with two surface-based micro-rain radars (MRR) located at two antarctic stations gives a near-perfect correlation between both datasets, even though climatic and geographic conditions are different for the stations. A better understanding and reassessment of CloudSat uncertainties ranging from −13 % up to +22 % confirms the robustness of the CloudSat retrievals of snowfall over Antarctica.

Pleistocene glacial history of the New Zealand subantarctic islands

The New Zealand subantarctic islands, in the Pacific sector of the Southern Ocean, provide valuable records of past environmental change. We find that the Auckland Islands hosted a small ice cap around 384 000 years ago, but that there was little glaciation during the Last Glacial Maximum, around 21 000 years ago, in contrast to mainland New Zealand. This shows that the climate here is susceptible to changes in regional factors such as sea-ice expanse and the position of ocean fronts.

Trends in global tropospheric ozone inferred from a composite record of TOMS/OMI/MLS/OMPS satellite measurements and the MERRA-2 GMI simulation

Both a 38-year merged satellite record of tropospheric ozone from TOMS/OMI/MLS/OMPS and a MERRA-2 GMI model simulation show large increases of 6–7 Dobson units from the Near East to India–East Asia and eastward over the Pacific. These increases in tropospheric ozone are attributed to increases in pollution over the region over the last several decades. Secondary 38-year increases of 4–5 Dobson units with both GMI model and satellite measurements occur over central African–tropical Atlantic.

Attributing the 2017 Bangladesh floods from meteorological and hydrological perspectives

In August 2017 Bangladesh faced one of its worst river flooding events in recent history. For the large Brahmaputra basin, using precipitation alone as a proxy for flooding might not be appropriate. In this paper we explicitly test this assumption by performing an attribution of both precipitation and discharge as a flooding-related measure to climate change. We find the change in risk to be of similar order of magnitude (between 1 and 2) for both the meteorological and hydrological approach.

Is geological mapping becoming obsolete?

Is geological mapping becoming obsolete?

Geology students typically experience some form of mapping education as part of their course and attitudes towards this baptism into the geosciences vary from adoration to utter hatred. Whatever the opinions of the students, however, it is widely recognised that performing mapping exercises is an excellent way to learn the basics of structural geology which underpins aspects of both further geological education and the use of geology in industry. Unfortunately, the number of graduates using the mapping skills practiced in …

Rainfall related geohazards: floods, landslides and mudslides in Rio - A dangerous combination of nature and human-related factors

Rainfall related geohazards: floods, landslides and mudslides in Rio - A dangerous combination of nature and human-related factors

Rainfall-related geohazards in Brazil’s poorer, mountainous city margins could be mitigated using better urban planning and communication. Our own Brazilian blogger Bárbara Zambelli Azevedo explores the problem and possible solutions. I come from Brazil, a country well-known for its beautiful landscapes, football and carnival. Ok, some stereotypes are true, indeed. Situated in the middle of the South American tectonic plate and away from geohazards such as earthquakes, volcanoes and tsunamis, this tropical country may seem like paradise to some. However, …
