𝐍𝐞𝐰 𝐩𝐞𝐫𝐬𝐩𝐞𝐜𝐭𝐢𝐯𝐞𝐬 𝐨𝐧 𝐨𝐮𝐫 𝐞𝐧𝐯𝐢𝐫𝐨𝐧𝐦𝐞𝐧𝐭 🛰 Earth observation from space plays an important role in helping scientists monitor our planet and generate the data to give us an accurate picture of our climate. Today, a number of European companies are working on exciting technologies to give us new insights into changes to our environment.  💙 We are proud to contribute to this important work through our optical components for satellite imaging systems. In this article in Laser Focus World, Jérémy Picot-Clémente, PhD features our near zero thermal expansion glass-ceramic ZERODUR® for its contribution to EUMETSAT's Meteosat Third Generation geostationary satellites, as part of its flexible combined imager. Launched in December 2022, MTG is helping scientists track changes in atmospheric water cycles, and provide better weather reporting and natural disaster predictions. ⬇ Check out the overview of European innovators in Earth observation technologies here: https://lnkd.in/eBjne58d

Why are our scientists looking at the colours of the ocean?  🌊 It's because you can tell a lot about the health of marine ecosystems and the impacts of climate change that way!  Now, there are two ways of doing this and both have their shortcomings.  1. Going on boats in the middle of the ocean.  🛥 Scientists collect seawater samples and then bring them to labs for analysis.   While this is a very precise method, it takes a lot of time and resources. It also offers only a small sample of the ocean. A drop in the ocean, we could say!  2. Using satellites, which can scan the whole Earth in a day.  🛰 While efficient, the problem is that the Earth's atmosphere interferes with what the satellites are picking up. Plus, the optical equipment needs to be calibrated. But unlike in labs, a scientist can’t physically calibrate the satellite equipment.    Combining both methods helps us overcome these shortcomings. And that's what the scientists working for the JRC Marine Optical Laboratory do!  Read more about their work here: https://lnkd.in/etTGpq-j #ClimateChange #EUScience EU Environment and Climate

At Tecnottica Consonni, our commitment to excellence in Photonics has driven us to innovate and contribute to environmental science. We are pleased to be featured in the article "Photonics innovations in climate observation: A view from Europe" by Jérémy Picot-Clémente from EPIC – European Photonics Industry Consortium!   As highlighted in the article, our work in designing and manufacturing Optical Components has played a crucial role in advancing climate observation technologies.   One of our proudest achievements is our contribution to the NEMO-HD microsatellite, a collaborative project supporting our long time OpticaGroup partner Optec SpA, where our components have enabled real-time multispectral and video imaging from Space. This cutting-edge technology is crucial for monitoring climate changes, natural disasters, and promoting the sustainable use of natural resources.   We are honored to be part of this transformative journey in environmental monitoring, a market expected to grow significantly in the coming years.   Thanks to Jérémy Picot-Clémente, PhD and EPIC - EUROPEAN PHOTONICS INDUSTRY CONSORTIUM for recognizing our efforts and highlighting our contribution to such an important cause.   Together, we are making strides towards a better, more sustainable future! 🌱🚀   SPACE-SI - Slovenian Centre of Excellence for Space Sciences and Technologies University of Toronto Institute for Aerospace Studies #Photonics #ClimateObservation #EnvironmentalScience #Sustainability

Detecting Artificial Greenhouse Gases on Exoplanets: Potential Sign of Technological Life Recent research by University of California, Riverside astrobiologist Edward Schwieterman and his team has unveiled intriguing possibilities in the search for extraterrestrial life: the detection of artificial greenhouse gases on exoplanets. These gases, designed to manipulate planetary climates, could serve as technosignatures indicating the presence of intelligent civilizations capable of terraforming or climate control.

Dear Colleagues ,   We invite you to submit your AGU24 abstract to our session "A119. Recent advances in aerosol representation and its impacts on climate, air quality and health". This session encourages efforts in modeling, observation, and theory to study aerosol microphysics, aerosol processes, and aerosol impacts. We are delighted to confirm our two invited authors: Prof. Randall Martin (WashU) and Dr. Cenlin He (NCAR).    Abstracts can be submitted to our session at https://lnkd.in/gcBwK5Gb. Please note the deadline for submissions is July 31, 2024 at 23:59 EDT.  Please see our session's details below.    Session A119 - Recent advances in aerosol representation and its impacts on climate, air quality and health   Atmospheric aerosols and their interaction with radiation and clouds represent the largest uncertainties in our understanding of the climate. Beyond the climatic effects, their implications on air quality and human health are also profound. This session seeks to bring together recent advances, including but not limited to the following topics: (1) theoretical, experimental, and modeling effort on aerosol microphysics; (2) characterization of aerosol interactions with radiation (ARI) and clouds (ACI); (3) aerosol interactions with the biosphere, such as light-absorbing particles with snow/ice albedo, and dust/biomass-burning aerosols with the biogeochemical cycle; (4) the impact of atmospheric particulate matter and its chemical components on air quality and human health in a changing climate; (5) aerosol-climate interventions, such as stratospheric aerosol injection, marine cloud brightening, and cirrus cloud thinning; (6) multidecadal variations of aerosols and their impacts on Earth system; and (7) aerosols' effect on extreme meteorological events.   We hope that you will join us in December and encourage the forwarding of this announcement to other colleagues who might be interested.   Sincerely, Xiaohan Li, Princeton University Ron L. Miller, NASA Goddard Institute for Space Studies Arman Pouyaei, Princeton University/NOAA Geophysics Fluid Dynamics Laboratory Qianqian Song, University of Maryland Baltimore County Enrico Zorzetto, New Mexico Institute of Mining and Technology

A recent Research Letter modeled the change in atmospheric aluminum content due to satellite burn-up and re-entry, which may lead to significant ozone depletion. The space industry is still young, but there's a long history of other emerging industries who created severe environmental issues that were mostly ignored in favor of short-term growth. We have an opportunity here to learn from those mistakes and take a more proactive and sustainable approach. https://lnkd.in/eNPyK5x9
