Nitrogen dioxide disparities in the time of COVID-19: How satellite data can facilitate environmental justice studies during this natural experiment and beyond

Around the world, the most vulnerable, marginalized, and racialized are disproportionately impacted by a variety of environmental stressors such as extreme heat, health-harming air pollution, and the growing impacts of climate change. In the United States, research has uncovered how Black and Brown communities and those with lower socioeconomic status are exposed to higher concentrations of many a ...[Read More]

What can we do to improve gender diversity in the workplace?

What can we do to improve gender diversity in the workplace?

The number of women in science and academia drops with each career step in the fields of science, technology, engineering and mathematics (STEM fields). This systematic under-representation of women towards the top of the academic career path is called the “leaky pipeline”. In Germany about 50% of the students in mathematics and natural sciences are women, but there are only 20% of fem ...[Read More]

February 2021: A dusty month for Europe

In February 2021, two major Saharan dust events hit Europe. Because of the prevailing weather conditions in the first and last week of February, several million tons of Saharan dust blanketed the skies from the Mediterranean Sea all the way to Scandinavia. The sandy sky was observed almost everywhere in Europe (Fig. 1). Moreover, the stained cars and windows indicated the dust deposition (Fig. 2 – ...[Read More]

EGU’s Climate: Past, Present & Future and Atmospheric Sciences Divisions welcome the US back into the Paris Climate Agreement

EGU’s Climate: Past, Present & Future and Atmospheric Sciences Divisions welcome the US back into the Paris Climate Agreement

As of 19 February 2021, the US officially re-joined the Paris Climate Agreement, a landmark international accord to limit global warming by 2°C (and ideally to 1.5°C) compared to pre-industrial levels. The Paris Climate Agreement aims to bring the world together to avoid catastrophic warming that will impact us all and to build resilience to the consequences of climate change that we are already s ...[Read More]

Using cloud microphysics to predict thunderstorms: How modelling of atmospheric electricity could save lives

Using cloud microphysics to predict thunderstorms: How modelling of atmospheric electricity could save lives

The last three decades were the warmest in the history of meteorological observations in Europe. Temperature rise is accompanied by an increase in the frequency and magnitude of extreme weather and climatic events, which are the main risks for population and environment associated with modern climate change. An important class of such phenomena includes severe rainfall, tornadoes, squalls, and thu ...[Read More]

A simple model of convection to study the atmospheric surface layer

A simple model of convection to study the atmospheric surface layer

Since being immortalised in Hollywood film, “the butterfly effect” has become a commonplace concept, despite its obscure origins. Its name derives from an object known as the Lorenz attractor, which has the form of a pair of butterfly wings (Fig. 1). It is a portrait of chaos, the underlying principle hindering long-term weather prediction: just a small change in initial conditions leads to vastly ...[Read More]

A brighter future for the Arctic

A brighter future for the Arctic

This is a follow-up from a previous publication. Recently, a new analysis of the impact of Black Carbon in the Arctic was conducted within a European Union Action. “Difficulty in evaluating, or even discerning, a particular landscape is related to the distance a culture has traveled from its own ancestral landscape. As temperate-zone people, we have long been ill-disposed toward deserts and ...[Read More]

Water vapor isotopes: a never ending story!

Water vapor isotopes: a never ending story!

Water stables isotopes are commonly exploited in various types of archives for their information on past climate evolutions. Ice cores retrieved from polar ice sheets or high-altitude glaciers are probably the most famous type of climate archives. In ice cores, the message about past temperature variations is conserved in the ice, formed from the snow falls whose isotopic composition vary with the ...[Read More]

The puzzle of high Arctic aerosols

The puzzle of high Arctic aerosols

Current Position: 86°24’ N, 13°29’E (17th September 2018) The Arctic Ocean 2018 Expedition drifted for 33 days in the high Arctic and is now heading back south to Tromsø, Norway. With continuous aerosol observations, we hope to be able to add new pieces to the high Arctic aerosol puzzle to create a more complete picture that can help us to improve our understanding of the surface energy budget in ...[Read More]

The perfect ice floe

The perfect ice floe

Current position: 89°31.85 N, 62°0.45 E, drifting with a multi-year ice floe (24th August 2018) With a little more than three weeks into the Arctic Ocean 2018 Expedition, the team has found the right ice floe and settled down to routine operations. Finding the perfect ice floe for an interdisciplinary science cruise is not an easy task. The Arctic Ocean 2018 Expedition aims to understand the linka ...[Read More]
