Validation of MODIS and GEOV1 fPAR Products in a Boreal Forest Site in Finland

open access: yesRemote Sensing, 2015
Remote sensing of the fraction of absorbed Photosynthetically Active Radiation (fPAR) has become a timely option to monitor forest productivity. However, only a few studies have had ground reference fPAR datasets containing both forest canopy and ...

Improving forest age estimation to understand subtropical forest regrowth dynamics using deep learning image segmentation of time‐series historical aerial photographs

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Accurately estimating forest age is key to understanding how forests recover and evaluating restoration success. We developed a two‐step deep learning approach using historical greyscale aerial photographs to map forest age at fine spatial scales. By combining a pre‐trained model with localized fine‐tuning, our U‐Net + ResNet50 architecture achieved ...

Gap-Filling of MODIS Fractional Snow Cover Products via Non-Local Spatio-Temporal Filtering Based on Machine Learning Techniques

open access: yesRemote Sensing, 2019
Cloud obscuration leaves significant gaps in MODIS snow cover products. In this study, an innovative gap-filling method based on the concept of non-local spatio-temporal filtering (NSTF) is proposed to reconstruct the cloud gaps in MODIS fractional snow ...

Urban Heat and Spatial Statistics, Toward Sustainable Cities and Society: A PRISMA‐Based Systematic Review and Empirical Assessment (2020–2025)

open access: yesSustainable Development, EarlyView.
ABSTRACT Over the past few decades, the intensification of global warming has brought increased attention to urban thermal dynamics, particularly regarding Land Surface Temperature (LST) and the Urban Surface Heat Island (SUHI) effect. This study conducts a systematic literature review alongside a bibliometric analysis of 123 peer‐reviewed articles ...

The apparent effect of orbital drift on time series of MODIS MOD10A1 albedo on the Greenland ice sheet

open access: yesScience of Remote Sensing
The NASA MODIS MOD10A1 snow albedo product has enabled numerous glaciological applications. The temporal consistency of MODIS albedo is critical to obtaining reliable results from this 22-year time series. The orbit of Terra began to drift toward earlier

Capability of Integrated MODIS Imagery and ALOS for Oil Palm, Rubber and Forest Areas Mapping in Tropical Forest Regions

open access: yesSensors, 2014
Various classification methods have been applied for low resolution of the entire Earth’s surface from recorded satellite images, but insufficient study has determined which method, for which satellite data, is economically viable for tropical forest ...

Madrasa Ideologies of English in Bangladesh: Questioning ELT‐Aid and Post‐9/11 De‐Islamization

open access: yesTESOL Quarterly, EarlyView.
Abstract External donors increasingly promote English as a notionally value‐neutral language of socioeconomic advancements in the Muslim South, overlooking local ideological diversities. Furthermore, national and Western forces deploy English as a tool to de‐Islamize madrasas (Islamic educational institutes) in the post‐9/11 world for global peace ...

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China 气候变化下中国大兴安岭漠河地区猞猁潜在适宜区的变化

open access: yesWildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Snowmelt predicts earlier breeding across the latitudinal range of an Arctic nesting seabird, the Little Auk (Alle alle)

open access: yesJournal of Animal Ecology, EarlyView.
Multi‐year monitoring of the crevice‐nesting High Arctic seabird, the Little Auk (Alle alle), across four colonies spanning distinct climatic regimes revealed that snowmelt timing is a key and consistent driver of breeding phenology. Earlier snowmelt advances access to nesting habitat, enabling birds to initiate reproduction sooner. These findings show
