Centre presents cloud computing & climate modelling at EGU assembly

Centre research was presented at the EGU Assembly 2017 in Austria this month, when geoscience experts and researchers from all over the world convened to discuss the Earth, planetary and space sciences.

The General Assembly 2017 of the European Geosciences Union (EGU) was held at the Austria Center, Vienna, from 23–28 April.

The scientific programme of the General Assembly includes special scientific and interdisciplinary events as well as oral, 'PICO', and poster sessions on topics covering the full spectrum of the geosciences and the space and planetary sciences.

The Centre was represented via a poster and an interactive PICO session:

Poster: Exceptional Arctic warmth of early winter 2016 and attribution to global warming (Tue, 25 Apr, 17:30–19:00, Hall X5)

This paper outlines an analysis of the record high temperatures in November and December in the North Pole and the surrounding Arctic region - with daily mean temperatures reaching 15 ºC above normal. November also saw a brief retreat of sea-ice that was virtually unprecedented in nearly 40 years of satellite records, followed by a record low in November sea ice area since 1850.

Unlike the Antarctic, Arctic lands are inhabited and their socio-economic systems are greatly affected by the impacts of extreme and unprecedented sea ice dynamics and temperatures, such as for example, the timing of marine mammal migrations, and refreezing rain on snow that prevents reindeer from feeding. The poster reports on multi-method rapid attribution analysis of these North Pole November-December temperatures.

PICO session (Presenting Interactive Content): Use of several Cloud Computing approaches for climate modelling: performance, costs and opportunities (Tue, 25 Apr, 08:46–08:48, PICO spot 5a)

Cloud Computing is a technological option that offers great possibilities for modelling in geosciences. Researchers studied how two different climate models can be adapted in different ways to run on Cloud Computing Environments using Amazon, Google and Microsoft. They also evaluated qualitatively how the use of Cloud Computing can affect the allocation of resources by funding bodies and issues related to computing security, including scientific reproducibility.

From a cost point of view, Cloud Computing moves researchers from a traditional approach where experiments were limited by the available hardware resources to monetary resources (how many resources can be afforded). As there is an increasing movement and recommendation for budgeting HPC projects on this technology, there could be a shift over the next years to consolidate Cloud as the preferred solution.
