Retrieving Hourly Aerosol Absorption From Space Using Physical Informed Deep Learning

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Retrieving aerosol absorption properties, such as single scattering albedo (SSA) and absorption aerosol optical depth (AAOD) from single‐view satellite observations remains a significant challenge. This study introduces the Physics‐Informed Neural Network for Aerosols (PINA) framework to retrieve hourly aerosol absorption properties from ...

Application of Species Distribution Models (SDMs) and Corridor Mapping for Conservation of an Endangered Charismatic Mammal: Brown Bear (Ursus arctos) in Iran

Ecology and Evolution, Volume 16, Issue 6, June 2026.
ABSTRACT The brown bear (Ursus arctos) is the largest terrestrial carnivore in Iran with a rapidly shrinking range. In this study, we assembled the most comprehensive and up‐to‐date distribution dataset of the brown bear in Iran. We applied Species Distribution Models (SDMs) and corridor mapping to identify this charismatic mammal's suitable habitats ...

Climate Change Reduces Habitat Suitability of the Endemic Iranian Ground‐Jay (Podoces pleskei): Spatial Analyses to Guide Conservation Strategies

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Pleske's ground jay (Podoces pleskei), an endemic bird of Iran's drylands, faces severe habitat loss due to climate change and human activities. Using ecological niche models and GIS analyses, we identified key environmental drivers of its distribution and found that 52% of suitable habitat is projected to be lost, with much of the remaining range ...
