Title: Hyperspectral Infrared (IR) Remote Sensing of the Atmosphere

Dr. Paolo Antonelli, PhD
Co-Founder and Director
Adaptive Meteo

Presentation short abstract: Hyperspectral Infrared (IR) remote sensing of the atmosphere involves the use of advanced sensors such as IASI and CrIS to collect data about the atmosphere in a large number of spectral bands. These sensors detect radiation in the IR part of the spectrum, which is absorbed and emitted by gases and particles in the atmosphere. By analysing the unique spectral signature of each atmospheric component, scientists can gain a better understanding of the composition and structure of the atmosphere. This information can be used to characterise the Earth’s atmospheric composition and dynamics. The ability of hyperspectral IR remote sensing technology to improve our understanding of the atmosphere has significant impacts in the fields of meteorology and climatology but it has also the potential to benefit other fields such as astronomy by mitigating the noise introduced by the Earth’s atmosphere. The presentation will cover the basics of hyperspecral remote sensing, current and future spaceborne sensors, and some of current and potential applications.

Short Bio: Paolo Antonelli (PhD) received his Ph.D. in Atmospheric and Oceanic Sciences from the University of Wisconsin – Madison in 2001 under the guidance of Prof. William L. Smith. His research focused on IR remote sensing of the Earth at high spectral resolution, and his dissertation work dealt with the application of Principal Component Analysis for data compression and data inversion. For about 15 years, Dr. Antonelli has been a research scientist at the University of Wisconsin-Madison Space Science and Engineering Center. In 2004/2005 Dr. Antonelli worked as coordinator of the Remote Sensing activities at the Mediterranean Agency for Remote Sensing and environmental control (MARSec) in Benevento Italy. Member of the MTG-IRS Advisory Group from 2014 to 2018, he has collaborated with EUMETSAT in the framework of MTG-IRS development, for the development of an High Performance Level 2 Validation and Demonstration Prototype, and for the development of a hyperspectral Level 2 Data Assimilation system. Since August 2017, Dr. Antonelli co-founded and directs Adaptive Meteo, an Italian start-up focused on innovative use of satellite data into Numerical Weather Prediction models and from 2018 he has been collaborating with the University of Hawaii in the field of IR hyperspectral Data Assimilation over the Pacific and over the Arctic.
