Stratospheric ozone from limb observations: validation of the profiles, evaluation of trends and their dynamical and chemical drivers (SOLVE)

Prime company: UNIVERSITY OF BREMEN (DE)

Living Planet Fellowship research project carried out by Carlo Arosio. The stratospheric ozone layer suffered a significant decline at the end of the 20th century as a consequence of anthropogenic emissions of halogenated substances. An ozone recovery has been predicted for the current century in response to the actions taken under the Montreal Protocol and …

Carlo Arosio

“What I greatly appreciated about the fellowship was ESA’s flexibility and support, especially during COVID-19 times, which made it possible to adapt the schedule and adjust some of the foreseen objectives according to the project development. The fellowship gave me the opportunity to independently manage a project for the first time and encouraged the collaboration …

Methane+

Prime company: Netherlands Institute for Space Research (NWO-I) (NL)

The ESA Methane+ project aims at exploiting the SWIR and TIR CH4 observations from different satellites in order to better differentiate between sources and sinks of CH4 on the regional and global scale. For this we will use the CH4 observations of TROPOMI on Copernicus Sentinel-5p, IASI on MetOp-B, and CrIS on Suomi NPP in combination with atmospheric inversion models. OBJECTIVES: Given the identified opportunities and challenges of …

A collaboration on Atmosphere science just kicked-off

Trace gases are produced and destructed by physical, biological and chemical processes. This natural cycle has been perturbed over the past decades by the global population increase and by the related boost of anthropogenic activities. The composition of the atmosphere is undergoing major and rapid changes with significant impacts on a global scale, affecting the …

Is the global COVID-19-related drop in NO2 pollution coming to an end?

All over the world, countries have – to a greater or lesser extent – taken measures to reduce the spread of the coronavirus. In particular, people movements have been restricted worldwide. The decrease in traffic and industrial activity, the two main sources of nitrogen dioxide (NO2) in urban areas, led to unprecedented decreases in NO2 …

INVESTIGATING LIGHTNING GENERATED ELF WHISTLERS TO IMPROVE IONOSPHERIC MODELS (ILGEW)

Prime company: INST PHYSIQUE GLOBE (FR)

Some of the strongest lightning discharges occurring at the Earth surface generate short electromagnetic signals that can propagate at very large distances both at the surface of the planet and in space. During a lightning discharge, the whole electromagnetic spectrum is excited, from radio frequencies to the visible and beyond. The conditions of the atmosphere …

Volcanic monItoring using SenTinel sensors by an integrated Approach (VISTA)

Prime company: GEO-K SRL (IT)

Volcanic monItoring using SenTinel sensors by an integrated Approach (VISTA) project is aimed at developing a novel ensemble of algorithms to completely characterized the effects of volcanic emissions on land and atmosphere. Volcanic activity is observed worldwide with a variety of remote sensing instruments, each one with advantages and drawbacks. Because a single remote sensing …

First TROPOMI-based emission estimates over South America

South America is a rapidly developing continent of planetary importance. It hosts the Amazon forest, which is the single largest source of biogenic volatile organic compound (BVOC) emissions into the global atmosphere; it is also a region where extremely violent and extensive wildfires are known to cause widespread damages and fatalities. In addition, the degradation …
