A central arctic extreme aerosol event triggered by a warm air-mass intrusion

Julia Schmale, Ivo Fabio Beck, Andrea Baccarini, Lubna Dada, Hélène Paule Angot

Frequency and intensity of warm and moist air-mass intrusions into the Arctic have increased over the past decades and have been related to sea ice melt. During our year-long expedition in the remote central Arctic Ocean, a record-breaking increase in temp ...

Automated identification of local contamination in remote atmospheric composition time series

Julia Schmale, Ivo Fabio Beck, Andrea Baccarini, Lubna Dada, Hélène Paule Angot

Atmospheric observations in remote locations offer a possibility of exploring trace gas and particle concentrations in pristine environments. However, data from remote areas are often contaminated by pollution from local sources. Detecting this contaminati ...

Survival of newly formed particles in haze conditions

Andrea Baccarini

Intense new particle formation events are regularly observed under highly polluted conditions, despite the high loss rates of nucleated clusters. Higher than expected cluster survival probability implies either ineffective scavenging by pre-existing partic ...

High-frequency gaseous and particulate chemical characterization using extractive electrospray ionization mass spectrometry (Dual-Phase-EESI-TOF)

Andrea Baccarini, Houssni Lamkaddam, Imad El Haddad, Mihnea Surdu

To elucidate the sources and chemical reaction pathways of organic vapors and particulate matter in the ambient atmosphere, real-time detection of both the gas and particle phase is needed. State-of-the-art techniques often suffer from thermal decompositio ...

Circum-Antarctic abundance and properties of CCN and INPs

Julia Schmale, Andrea Baccarini

Aerosol particles acting as cloud condensation nuclei (CCN) or ice-nucleating particles (INPs) play a major role in the formation and glaciation of clouds. Thereby they exert a strong impact on the radiation budget of the Earth. Data on abundance and prope ...

Exploring the coupled ocean and atmosphere system with a data science approach applied to observations from the Antarctic Circumnavigation Expedition

Katherine Colby Leonard, Robin Lewis Modini, Jenny Thomas, Fernando Perez Cruz, Julia Schmale, Christel Sybille Hassler, Irina Gorodetskaya, Sebastian Johannes Heinz-Josef Landwehr, Andrea Baccarini, Alireza Moallemi

The Southern Ocean is a critical component of Earth's climate system, but its remoteness makes it challenging to develop a holistic understanding of its processes from the small scale to the large scale. As a result, our knowledge of this vast region remai ...

Sources, Occurrence and Characteristics of Fluorescent Biological Aerosol Particles Measured over the Pristine Southern Ocean

Robin Lewis Modini, Julia Schmale, Sebastian Johannes Heinz-Josef Landwehr, Andrea Baccarini, Alireza Moallemi

In this study we investigate the occurrence of primary biological aerosol particles (PBAP) over all sectors of the Southern Ocean (SO) based on a 90-day dataset collected during the Antarctic Circumnavigation Expedition (ACE) in austral summer 2016-2017. S ...

New Insights Into the Composition and Origins of Ultrafine Aerosol in the Summertime High Arctic

Julia Schmale, Andrea Baccarini

The summertime high Arctic atmosphere is characterized by extremely low aerosol abundance, such that small natural aerosol inputs have a strong influence on cloud formation and surface temperature. The physical sources and the mechanisms responsible for ae ...

Low‐Volatility Vapors and New Particle Formation Over the Southern Ocean During the Antarctic Circumnavigation Expedition

Robin Lewis Modini, Julia Schmale, Andrea Baccarini

During summer, the Southern Ocean is largely unaffected by anthropogenic emissions, which makes this region an ideal place to investigate marine natural aerosol sources and processes. A better understanding of natural aerosol is key to constrain the preind ...

Insights into the molecular composition of semi-volatile aerosols in the summertime central Arctic Ocean using FIGAERO-CIMS

Julia Schmale, Andrea Baccarini

The remote central Arctic during summertime has a pristine atmosphere with very low aerosol particle concentrations. As the region becomes increasingly ice-free during summer, enhanced oceanatmosphere fluxes of aerosol particles and precursor gases may the ...

Pollution Detection Algorithm (PDA)

Julia Schmale, Ivo Fabio Beck, Andrea Baccarini, Hélène Paule Angot

The Pollution Detection Algorithm (PDA) is an algorithm to identify and flag periods of primary polluted data in remote atmospheric time series in five steps. The first and most important step identifies polluted periods based on the gradient (time-derivat ...

Progress in Unraveling Atmospheric New Particle Formation and Growth Across the Arctic

Julia Schmale, Andrea Baccarini

New particle formation (NPF) and growth can be an important source of cloud condensation nuclei for the Arctic atmosphere, where cloud formation is sensitive to their availability. Low-level clouds influence the Arctic energy budget, and likely contribute ...

Frequent new particle formation over the high Arctic pack ice by enhanced iodine emissions

Julia Schmale, Andrea Baccarini

In the central Arctic Ocean the formation of clouds and their properties are sensitive to the availability of cloud condensation nuclei (CCN). The vapors responsible for new particle formation (NPF), potentially leading to CCN, have remained unidentified s ...

Sulfuric acid condensation sink calculated for the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

The condensation sink is a measure of the sulfuric acid lifetime against condensation on preexisting aerosol particles. Dimensionally it is the inverse of a time (reported in per second) and it is calculated starting from the aerosol size distribution. A l ...

Ozone concentration measured during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Ozone was measured with a 2B Technology ozone monitor (model 205). The concentration is reported as a mixing ratio in parts per billion [ppb], at 60 seconds average. Ozone is a trace gas that can be formed directly in the troposphere (the most important fo ...
