Atmospheric particles are incredibly diverse in terms of their physical and chemical properties. We typically refer to the suspension of these particles in the atmosphere as “aerosols”. The physical and chemical properties of aerosols determine their lifecycle and climatic and air quality impacts. These properties include particle size, chemical composition, and affinity for water, which determines their ability to interact with water vapor and clouds. Additionally, when looking under an electron microscope, one sees that these particles have very different shapes, and several components can mix with different geometrical structures. These additional geometrical and topological properties also affect how the particles transform in the atmosphere, and how they interact with solar radiation and clouds. Eventually, these interactions determine their optical properties and finally their warming or cooling potentials. In this seminar, I will talk about a particular category of atmospheric particles, namely, light-absorbing aerosols. These particles in addition to scattering the solar radiation also absorb it. I will also discuss how one can measure some of the properties of these particles and the associated challenges. I will conclude my talk by providing a brief overview of our atmospheric sciences program and some of the current research fields at Michigan Technological University.

Claudio Mazzoleni is a Professor in the Physics Department and the Atmospheric Sciences Program at Michigan Technological University, where he started his academic career in 2008. He earned a Laurea in Physics in 1995 at the University of Trento, Italy, and a Ph.D. in Atmospheric Sciences in 2003 at the Desert Research Institute of Reno, NV. He was a post-doc at the Los Alamos National Laboratory from 2005 to 2008. He is currently on sabbatical leave in Europe. His research focuses on the study of atmospheric particles with an emphasis on their optical and morphological properties.

Vi lasciamo un abstract del seminario e la biografia della Dott.ssa V. Pavan.

Within the project "Highlander", Arpae Simc set up an operational climate service addressed to support irrigation water management in agriculture, by providing mid-term information between probabilistic seasonal forecasts and short-term view of deterministic  +7-day forecasts.
The product take as input the sub-seasonal (+4 weeks) forecasts operationally produced, interpolated over Emilia Romagna at 5 km resolution and calibrated using the EcPoint technique by ECMWF, together with information on agricultural land use from satellite data, soil map and observed weather data from Arpae Simc. All these data are taken as inputs of the agro-hydrological model CRITERIA-1D (, computing the crop development and crop water needs.
The sub-seasonal irrigation forecasts are operationally produced since 2021 for three Land Reclamation and Irrigation Boards (Consorzi di Bonifica in Italian), which are the authorities in charge of water management for agriculture (water storage, transportation and distribution): the Burana, Renana and Romagna Irrigation Consortia. Operational output data are +4 weeks irrigation and precipitation forecasts expressed as a statistical distribution. The results obtained validating irrigation probabilistic forecasts for summer 2022 against observed water use in a group of farms are described and analysed.

Valentina Pavan has been working at Arpae-Simc as climatologist since 2001 and since 2021 contributes to the technical coordination of the Arpae Climate Observatory of Emilia-Romagna. Among her duties are the description of climate and climate variability, both at reagional and national level, the contribution to development of objective analyses of surface meteorological parameters both at regional and at super-regional level. She is also an expert of seasonal predictions and contributes  to the Technical Working Group on monthly and seasonal predictions coordinated by the National CIvil Protection Department. She gained her laurea at the Physics department of Bologna University in 1988 and a PhD in Atmospheric and Oceanic Sciences at Princeton University (USA) in 1993.

Seminario di Meteorologia Ambientale a cura di Claudia Acquistapace

L’Istituto di Geofisica e Meteorologia dell’Università di Colonia ha annunciato che il prossimo Giovedì 25 maggio 2023, alle ore 14:30 (ora italiana) si svolgerà il seminario dal titolo: “What did we learn with the EUREC4A dataset?
A look at clouds and precipitation in the Tropics”
, curato dalla Dott.ssa Claudia Acquistapace. Il seminario si svolgerà sia in presenza presso la Lecture Room 1P – DICAM – Università of Trento, Via Mesiano 77 Trento, sia online al seguente link Zoom: (ID: 835 4359 4724, Passcode: 052914). Vi riportiamo un abstract del seminario e la biografia della dottoressa:

Almost three years ago, just before the pandemic, the EUREC4A field campaign was taking place, deploying a wide array of observational platforms in and over the tropical Atlantic Ocean around Barbados. The significant scope of the campaign was quantifying macrophysical properties of trade-wind cumuli as a function of the large-scale environment and providing a reference data set that may build a benchmark for the modeling and the satellite observation of shallow clouds and circulation. In addition to these big research questions, the observations allow for  investigating the trades' precipitation life cycle, including how precipitation  relates to evaporation and cold pools. Today, a special issue on  Earth System Science Data [1]  collects the datasets that have been produced, and more are still yet to come.  In this talk, we will go over the primary scientific outcomes from the EUREC4A campaign and discuss the latest research on mesoscale organization patterns as seen from satellites. We will also look at unique ship-based observations of clouds and rain. We will discuss how they interact with the ocean underneath and impact the atmospheric boundary layer humidity. Finally, we will discuss future challenges, still-open research questions, and opportunities for future studies.

Claudia’s path starts in Pisa, where she got her bachelor degree in general Physics, and then went on in Bologna, where she completed her master in physics focusing on atmosphere with a thesis on satellite remote sensing of light precipitation in Europe. Then, she moved to Cologne for completing a PhD within the Marie Curie initial training network focusing on drizzle detection but this time from the ground, using cloud radar Doppler spectra, for which she was awarded with the
Reinhard-Süring-Stiftung 2019 Research award. She employed her first post-doc to use her observations to evaluate the performance of the ICON-LEM model. She was then actively taking part in the EUREC4A measurement campaign as PI on the research vessel Maria S. Merian, conducting radar ship-based observations of clouds and rain in the tropics.
Currently she is completing a master in science communication at the University of Trento and she will soon start her new position as junior research group leader in Cologne, coming back to satellite remote sensing, this time for better understanding extreme precipitation events using machine learning methods.
She is the science communication manager of the PROBE Cost Action and she also got funding for outreach projects, like the videodocumentary on women in science “Wetoo: what they don’t tell you” [2] and for the realization of an outreach video on atmospheric boundary layer [3], which was awarded by the AISAM association with a communication price.

Seminario di Meteorologia Ambientale – Fatima Pillosu

Per la serie “Environmental Meteorology Seminar”, vi segnaliamo il seminario di Fatima Pillosu (European Centre for Medium-range Weather Forecasts and University of Reading, Reading, UK) dal titolo: “ecPoint, post-processing of global ensemble rainfall forecasts: current efforts and future challenges to improve the prediction of extreme localized rainfall events and flash floods at global scale”.

Il seminario si terrà Giovedì 20 Ottobre 2022 alle ore 14:30, online attraverso la piattaforma Zoom ( – Meeting ID: 857 9637 7450, Passcode: 182580) e in presenza sarà riprodotto nell’Aula 2Q del Dipartimento di Ingegneria Civile, Ambientale e Meccanica (DICAM) presso l’Università degli Studi di Trento, in Via Mesiano 77 (38123, Trento).

Vi lasciamo un abstract e la biografia di Fatima Pillosu in basso:

ECMWF has always been at the forefront of numerical weather prediction
(NWP) model development, often ranking as one of the world’s leading
centres for weather prediction. ECMWF’s Integrated Forecasting System
(IFS) covers the global domain, different time horizons (e.g.,
medium-range, sub-seasonal and seasonal), and consists of several
components (e.g., the atmospheric general circulation model, the ocean
wave model, the land-surface model, and the perturbation models for data
assimilation and generation of forecast ensembles). Any NWP model
divides the Earth’s surface into grid boxes and predicts one value
(e.g., for rainfall or temperature) per grid box. The sizes of such
grid-boxes vary depending on the model, from 1 to 5 km for regional
high-resolution models to 10 to 50 km for global lower-resolution
models. At ECMWF, great efforts are made to consistently increase the
resolution of their NWP models to provide their users with better
forecasts for specific locations, especially for extreme events (e.g.,
wind gusts, convective storms, and flash floods). Currently, the global
ensemble forecasts (ENS) are provided at 18 km and are expected to go to
9 km next year. However, if weather varies markedly within a grid box or
the predictability of the atmosphere is low, forecasts for specific
sites will inevitably fail due to biases or representativeness errors in
the model. By post-processing the raw NWP forecasts, it is possible to
provide better predictions for specific locations. ecPoint has been one
of the first post-processing projects at ECMWF, mainly to anticipate
sub-grid variability and biases in rainfall forecasts. Currently,
ecPoint provides global point-scale rainfall forecasts up to day 10 to
ECMWF users worldwide. Furthermore, ongoing investigations are carried
out on how to use ecPoint products to predict one of the most
devastating natural hazards: flash floods. The seminar will provide an
overview of the ecPoint post-processing technique. It will also discuss
the research behind the definition of a global layer in the GloFAS
platform that will use ecPoint forecasts for the global prediction of
flash floods at medium ranges, which hopes to help mainly humanitarian
actions in developing countries.

Fatima Pillosu is a researcher at the European Centre for Medium-range
Weather Forecasts (ECMWF, Reading, UK) and a PhD student at the
University of Reading (Reading, UK). After obtaining a bachelor’s
degree in civil engineering at the University of Cagliari, she
specialised in hydrology through an MSc in Hydraulic Engineering at the
University of Cagliari with a thesis that analysed the change in
frequency of extreme rainfall events and flash floods in Sardinia. This
latter work encouraged her to gain experience in meteorological science,
which led her to a 1-year internship at ECMWF in 2016. The project
focused on developing an innovative post-processing technique (called
ecPoint) to determine the degree of sub-grid variability and biases in
short- to medium-range rainfall forecasts. In 2019, this research
project became operational at ECMWF, providing global point-scale
rainfall forecasts to ECMWF users worldwide. In 2017, she also started a
PhD at the University of Reading to investigate the utility of such new
post-processed rainfall forecasts for hydrological predictions, focusing
mainly on flash flood forecasting.

This series of seminars is primarily targeted to Students attending our
double-degree programme of MSc in Environmental Meteorology [1].
However all those who are interested are more than welcome to join!
