Satellite versus ground-based estimates of burned area: a comparison between MODIS based burned area and fire agency reports over North America in 2007 [PDF]

open access: yes, 2015
North American wildfire management teams routinely assess burned area on site during firefighting campaigns; meanwhile, satellite observations provide systematic and global burned-area data.

Long‐term benefits of burns for large mammal habitat undermined by large, severe fires in the American West

open access: yesEcography, EarlyView.
Escalating wildfire frequency and severity are altering wildland habitats worldwide. Yet investigations into fire impacts on wildlife habitat rarely extend to the macroecological scales relevant to species conservation and global change processes. We evaluate the effects of wildfire on habitat quality and selection by large mammals spanning three ...

Spatiotemporal Variation of Ecological Quality in the Yinshan Mountains Detected by MODIS Remote Sensing Indicators. [PDF]

open access: yesEcol Evol
A comprehensive ecological index MRSEI based on MODIS was proposed. The new indicators of greenness, humidity, and dryness are more applicable to the ecological evaluation of the desertification steppes. The introduction of comprehensive salinity index can effectively reflect the issue of soil salinization. FROM‐TO vector transformation can effectively

Trends in MODIS and AERONET derived aerosol optical thickness over Northern Europe [PDF]

open access: yes, 2019
Long-term Aqua and Terra MODIS (MODerate resolution Imaging Spectroradiometer) Collections 5.1 and 6.1 (c051 and c061, respectively) aerosol data have been combined with AERONET (AERosol RObotic NETwork) ground-based sun photometer observations to ...

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

open access: yesGlobal Change Biology Communications, EarlyView.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

Fingerprint of rice paddies in spatial-temporal dynamics of atmospheric methane concentration in monsoon Asia. [PDF]

open access: yes, 2020
Agriculture (e.g., rice paddies) has been considered one of the main emission sources responsible for the sudden rise of atmospheric methane concentration (XCH4) since 2007, but remains debated.

Oil spill detection using optical sensors: a multi-temporal approach [PDF]

open access: yes, 2018
Oil pollution is one of the most destructive consequences due to human activities in the marine environment. Oil wastes come from many sources and take decades to be disposed of.

Sustainability Performance and Corporate Risk: Evidence From the Tourism Industry

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the impact of sustainability performance (Refinitiv Environmental, Social, and Governance [ESG] scores) on corporate risk (CR). We apply stakeholder theory and the resource‐based view to an international sample of 247 tourism firms from 2002 to 2018.

Synthetic RapidEye data used for the detection of area-based spruce tree mortality induced by bark beetles

open access: yesGIScience & Remote Sensing, 2018
Tree mortality caused by outbreaks of the bark beetle Ips typographus (L.) plays an important role in the natural dynamics of Norway spruce (Picea abies L.) stands, which could cause far-reaching changes in the occurrence and duration of vegetation ...
