Beirut Power: Trends and Turning Points

Payne Institute Communications Associate Elsa Barron, Earth Observation Group Senior Research Associate Christopher Elvidge and Research Associate Feng-Chi, Hsu write about how in Beirut, it plunged the 2.4 million-person city into darkness this weekend. The Lebanese power grid shut down on Saturday due to depleted fuel resources, which comes after months of economic crisis in the country. October 14, 2021.

Colorado’s Skies Really Are That Much Smokier As Western Wildfires Worsen 9/28/2021

Colorado’s Skies Really Are That Much Smokier As Western Wildfires Worsen

Payne Institute Earth Observation Group Research Associate Tamara Sparks contributes to this article about how a surge of large wildfires in the West, fueled in part by climate change, has increased the number of days residents are breathing smoke across nearly every part of Colorado.  The number of days with smoky skies has grown over the last decade, the data show, blanketing Colorado from the Eastern Plains to the Western Slope — including northern parts of the state and the heavily populated Front Range corridor.  September 28, 2021.

Tallgrass to track, measure emissions on U.S. interstate natural gas pipeline

The Payne Institute is a data science partner with Project Canary to help Tallgrass Energy Partners monitor emissions, including methane and other greenhouse gases, on its Rockies Express Pipeline, making it the first U.S. company to measure the environmental impact of operations on an interstate natural gas pipeline.  September 28, 2021.  

WILDFIRES THREATEN LARGEST TREE IN THE WORLD 9/22/2021

WILDFIRES THREATEN LARGEST TREE IN THE WORLD

Payne Institute Earth Observation Group student worker Elijah Mt.Castle writes about how multiple wildfires in Sequoia National Park have burned a total of 43,375 acres. The park is home to the world’s largest tree by volume, the General Sherman Tree. Sequoia trees are the largest species of trees by volume and can live to be over 2,000 years old. To protect the Tree and other large ancient trees, firefighters have wrapped the base of the trunks with fireproof blankets.  September 22, 2021.

A First look at the New Orleans power outage 9/2/2021

A First look at the New Orleans power outage

The Payne Institute Earth Observation Group uses satellite detection to look at the large scale power outage in Louisiana on September 2, 2021.  Category 4 hurricane Ida made landfall near Port Fourchon, LA on August 29, 2021 at 16:55UTC.  The aftermath caused significant power outages in LA.   The image shows how nighttime lights around New Orleans after the storm compare to what is typical.  The outage are is in red, normal power supply is in yellow, and terrain and clouds are in blue.  The data was collected by JPSS NPP satellite on September 2, 2021 between 1am and 3am local time.  September 2, 2021.

Lights of a City Under Siege – Disruption to Kandahar Airport Lights Increases as the Taliban Entered the City

Payne Institute Communications Associate Brooke Bowser, Earth Observation Group Senior Research Associate Christopher Elvidge, and Director Morgan Bazilian write about how the airport in Kandahar, Afghanistan has been impacted as U.S. troops began their withdrawal from a 20-year conflict, and the Taliban steadily gained more ground in the city.  August 25, 2021.

Measuring Gas Flaring in Russia with Multispectral VIIRS Nightfire 8/5/2021

Measuring Gas Flaring in Russia with Multispectral VIIRS Nightfire

Payne Institute Earth Observation Group Researcher Mikhail Zhizhin, Alexey Matveev, Researcher Tilottama Ghosh, Researcher Feng‐Chi Hsu, Martyn Howells, and Senior Researcher Christopher Elvidge write about the data reported by the international and governmental agencies, the Russian Federation remains one of the world’s major associated petroleum gas (APG) flaring nations. In the past decade, numerous studies have shown the applicability of satellite-based methods to estimate gas flaring. New satellite-based observations might offer an insight in region-, company-, and site-specific gas flaring patterns, as the reported data are often incomplete. We provide a detailed catalog of the upstream and downstream gas flares and an in-depth analysis at the country, region, company and site level of the satellite monitoring results of flaring in Russia from 2012 to 2020.  August 5, 2021. 

Identification of Smoldering Peatland Fires in Indonesia via Triple-Phase Temperature Analysis of VIIRS Nighttime Data 7/28/2021

Identification of Smoldering Peatland Fires in Indonesia via Triple-Phase Temperature Analysis of VIIRS Nighttime Data

The Payne Institute Earth Observation Group researchers Christopher D. Elvidge, Mikhail Zhizhin, Feng-Chi Hsu, and NOAA researcher Kimberly Baugh have contributed to the book titled Biomass Burning in South and Southeast Asia.  They apply a spectral un-mixing procedure to uniquely identify low-temperature (320–500 K) peatland smoldering in Indonesia using nighttime data collected by the Visible Infrared Imaging Radiometer Suite (VIIRS). The analysis begins with the detection of subpixel infrared (IR) emitters in six spectral bands spanning the near-infrared (NIR), shortwave infrared (SWIR), and midwave infrared (MWIR). With sunlight eliminated, the NIR and SWIR radiances can be fully attributed to the IR emitter. July 28, 2021.
