Assessing the environmental impacts of the Capilla del Monte wildfire in Punilla Valley of Argentina using Landsat-9 and Sentinel-5P
Furkan Yilgan, Nilay Yildiz, Tugba Dogan
TL;DR
This study assesses the environmental impact of a wildfire in Argentina using satellite data to analyze changes in vegetation, soil moisture, and air quality.
Contribution
The novel use of Landsat-9 and Sentinel-5P data together provides a comprehensive assessment of wildfire effects on both land and atmospheric conditions.
Findings
Vegetation cover increased by 35% and soil moisture decreased by 16% after the wildfire.
Burned area estimates ranged from 387.9 to 392.4 km² using different methods.
High concentrations of NO2 and CO were detected, posing health risks to local inhabitants.
Abstract
Wildfires are a growing environmental concern due to rapid population growth, urbanization, and human activities, which contribute to climate change, causing wildfires that damage ecosystems and the environment. Wildfires destroy the vegetation cover, habitat of habitants and cause soil deterioration by changing the soil structure. In addition, toxic gases released into the atmosphere during fires threaten the lives of habitants. The effects of the forest fire that occurred on 19th September 2024 around Capilla del Monte in the Punilla Valley were analyzed using spectral indices. Landsat-9 data were used to detect changes in vegetation cover, land surface temperature (LST), and soil moisture by comparing the pre- and post-fire satellite images, while Sentinel-5P TROPOMI satellite data were used to extract the concentration of nitrogen dioxide (NO2) and carbon monoxide (CO) gases.…
