Climatic Drivers of the Area Burned by Winter Wildfires in Northern Italy

International Journal of Climatology, EarlyView.
This study investigates winter wildfires occurring between November and April in northern Italy over the period 2008–2022. By integrating high‐resolution burned‐area data with gridded climatic indices derived from 150 weather stations, it identifies spatial and temporal wildfire patterns, highlights the most fire‐prone mountain areas through pixel ...

Station‐Based Assessment of Sub‐Seasonal Climate Trends in the Tyrolean Alps (Austria)

International Journal of Climatology, EarlyView.
In this study, we quantify the magnitude and significance of sub‐seasonal trends in the Tyrolean Alps (Austria) by collecting, processing and analysing meteorological observations from a dense network of climate stations. Our analysis indicates a warming rate of 0.43°C/dec over 1964–2023, greater sub‐seasonal trend variability when the analysis window ...

Machine Learning‐Based Correction of Reanalysis Surface Radiation Fluxes Using Ground‐Measured Data in the Southern Brazilian Pampa Biome

International Journal of Climatology, EarlyView.
This study demonstrates that ERA5 provides more accurate surface radiation flux estimates than MERRA2 across the Southern Brazilian Pampa. Machine learning models, particularly Random Forest, further improved the precision of reanalysis data for climate applications.

Aerosol and non-aerosol drivers of regional trends in top-of-atmosphere albedo over 2002–2020

Environmental Research Letters
Climate change responds to, and in turn modifies, trends in the Earth’s top-of-atmosphere (TOA) albedo. These trends are caused in particular by anthropogenic aerosol-radiation and aerosol-cloud interactions, as well as by non-aerosol feedbacks involving

How well do the regional atmospheric and oceanic models describe the Antarctic sea ice albedo? [PDF]

The Cryosphere
We assessed how well regional climate models (HCLIM, MAR, RACMO), ocean models (MetROMS-UHel, NEMO), and ERA5 reanalysis simulate Antarctic sea ice albedo, snow, and ice thickness, using in situ data from field campaigns (ISPOL, Weddell Sea, in December ...

Estimating Land Degradation Level Using Remote Sensing Data and Fuzzy AHP Technique

Land Degradation &Development, EarlyView.
ABSTRACT Land degradation is a critical global environmental concern that significantly impacts ecosystem services, agricultural productivity, weather patterns, human livelihoods and overall well‐being. Prompt and precise assessments of land degradation status are crucial for environmental governance and sustainable development. Remote sensing data can

Land Surface Albedo Estimation from Chinese HJ Satellite Data Based on the Direct Estimation Approach

Remote Sensing, 2015
Monitoring surface albedo at medium-to-fine resolution (<100 m) has become increasingly important for medium-to-fine scale applications and coarse-resolution data evaluation.

Robust Performance Loss Rate Calculation for Photovoltaic Systems in High Latitude Locations

Progress in Photovoltaics: Research and Applications, EarlyView.
This work studies the best methods for performance loss rate (PLR) calculation in high latitude locations, characterized by strong seasonal variability. As the different methods can drastically affect the PLR value, an ensemble method consisting of multiple approaches was validated to be essential in identifying robust PLRs.

Disposition Model for Permafrost Degradation in Mountainous Regions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.
