A climate‐sensitive tropical urbanism under extreme heat†

Singapore Journal of Tropical Geography, EarlyView.
Tropical urban dwellers face twin climate challenges that impinge on their quality of life: climate overheating and the urban heat island (UHI). The latter superimposed on the former to lead to high levels of thermal discomfort, carbon and energy consequences.

Improvements in aerosol layer height retrievals from TROPOMI oxygen A-band measurements by surface albedo fitting in optimal estimation [PDF]

Atmospheric Measurement Techniques
The aerosol layer height (ALH), from the Sentinel-5P/TROPOMI L2_AER_LH product, is based on an optimal estimation (OE) approach, fitting cloud-free measurements to synthetic reflectances in the strongest oxygen absorption band, provided by a neural ...

Surface albedo darkening from wildfires in northern sub-Saharan Africa

Environmental Research Letters, 2014
Northern sub-Saharan Africa (NSSA) has a wide variety of climate zones or biomes, where albedo dynamics are highly coupled with vegetation dynamics and fire disturbances.

Unlocking Urban Climate Change Analysis in Global Kilometer‐Scale Climate Simulations

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Coupled multi‐decadal global km‐scale simulations completed in recent years open new perspectives in the investigation and understanding of urban climate change. This study introduces a generic method for extracting urban areas and their rural references worldwide and validates it on hourly timescales with remote‐sensing observations of land ...

Dark Land Surfaces Allow for Refugia That Could Support Photosynthetic Life on the Surface of Snowball Earth

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Photosynthetic eukaryotic algae survived the Neoproterozoic Snowball Earth events, indicating that liquid‐water refugia existed somewhere on the surface. We examine the potential for refugia at the coldest time of a snowball event, before CO2 had risen and with high‐albedo ice on the frozen ocean, before it became darkened by dust deposition ...

Effects of Wintertime Snow Depth Assimilation on Summertime Sea Ice Prediction Experiments Utilizing a Fully Coupled Regional Arctic Model With Perfect Boundary Conditions

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract During the past decades, the rapid decline of sea ice in the Arctic Ocean has substantially favored commercial navigation activities in the summertime. Numerical sea ice prediction on a seasonal scale plays a crucial role in guiding the programme of such activities, yet the role of snow depth data assimilation in numerical sea ice prediction ...

Soil Moisture Impact on Convective Initiation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The influence of soil moisture on convective storm initiation remains an open question, with previous studies showing conflicting results regarding whether storms preferentially form over wet or dry soils. Here, we analyze the soil moisture‐convection relationship using satellite observations across North America, Africa, and Australia from ...

Addressing Uncertainties in Climate–Ecosystem Feedbacks in the Arctic: Ten Priority Research Questions for Integrated Observation and Modeling

Ecological Research, Volume 41, Issue 4, July 2026.
Uncertainties exist in the biosphere–climate feedbacks in the Arctic. Remote and ground measurements play complementary roles in detecting possible changes. A critical next step is identification of key drivers of the global changes for future projections. ABSTRACT Positive biosphere–climate feedbacks are likely to amplify the Arctic warming, yet major

Megagrazer loss drives complex landscape-scale biophysical cascades

Environmental Research Letters
Wild animals can modulate ecosystem-climate feedbacks, e.g. through impacts on vegetation and associated carbon dynamics. However, vegetation cover and composition also affect land surface albedo, which is an important component of the global energy ...

From Remotely‐Sensed Data of Norwegian Boreal Forests to Fast and Flexible Models for Estimating Surface Albedo

Journal of Advances in Modeling Earth Systems, 2018
The importance to consider changes in surface albedo and go beyond simple carbon accounting when assessing climate change impacts of forestry and land use activities is increasingly recognized.
