Interactive map illustrates the impact of coronavirus on global pollution


In an effort to track the impacts, Earther assembled an interactive map to explore the changes in air pollution not just in the U.S. but globally. The map runs on Google Earth Engine and uses data collected by the European Space Agency’s Sentinel-5P satellite, which circles the Earth capturing various types of data. It includes four snapshots from December 2019 through March 20, 2020. The Sentinel satellite data shows nitrogen dioxide, which is a handy proxy for human activity.



Brian Kahn and Dhruv Mehrotra of Earther highlight a recently launched pollution visualizer their team has assembled that highlights the stark changes in human activity across the world in the wake of COVID-19-imposed economic and social disruptions. 

The authors interview Barbara Dix, an atmospheric researcher with the Cooperative Institute for Research in Environmental Sciences at the University of Colorado at Boulder who explains, “We are now witnessing a global experiment where one emission source is rapidly turned down (NOx), while other sources are still up or will decrease more slowly. A lot of atmospheric science will come out of this.”

The interactive map, which uses satellite data from the European Space Agency’s Sentinel-5P satellite and runs on the Google Earth Engine, can be accessed here.

Wood Urbanism

Resim
Wood Urbanism: From the Molecular to the Territorial Daniel Ibañez, Jane Hutton, Kiel Moe (Editors) Actar Publishers , November 2019 Hardcover | 8 x 10-1/4 inches | 488 pages | English | ISBN: 978-1945150814 | $54.95 PUBLISHER'S DESCRIPTION : Wood holds unique and timely lessons for urbanization, yet it remains inadequately characterized in architecture, landscape architecture, and urbanism. From under-considered thermal properties to emerging manufacturing possibilities, from changing forestry regimes to larger carbon cycle dynamics, Wood Urbanism explores the unique material and scalar properties of wood, presenting it as a critical material for design today. It brings into conversation scholars and practitioners who focus on wood from a range of perspectives: from the working forest to the mid-rise building to the basic cell. Drawing from the inherent intelligence and depth of multiple disciplines, this book offers a transcalar perspective on the role of wood in cont...

Building a gentrification early warning system with big data

Resim
But what if there were a way to see gentrification long before the coffee shops, condos and Whole Foods appear? What if city planners and neighborhoods had an early warning system that could sniff out the changes just as they begin? [...] neighborhood advocates would have the opportunity to implement policies ranging from reserving affordable housing units to educating residents of their renting rights to helping small businesses negotiate long-term lease extensions. In his NPR piece, astrophysics professor Adam Frank explains how various big data sets, like housing prices, eviction records, census data, or social media usage, can be utilized for "predictive analytics" to detect early onsets of gentrification for specific neighborhoods at an increasingly high resolution — and what significant perils come with it.
