Open AccessExploring super-resolution spatial downscaling of several meteorological variables and potential applications for photovoltaic power
We applied a perfect prognosis approach to downscale four meteorological variables that affect photovoltaic (PV) power output using four machine learning (ML) algorithms. In addition to commonly investigated v...

Open AccessExtreme fire weather in Chile driven by climate change and El Niño–Southern Oscillation (ENSO)
A string of fierce fires broke out in Chile in the austral summer 2023, just six years after the record-breaking 2017 fire season. Favored by extreme weather conditions, fire activity has dramatically risen in...

Open AccessSpaceborne NO2 observations are sensitive to coal mining and processing in the largest coal basin of Russia
Coal use exacerbates several major environmental problems including build-up of greenhouse gases and air quality deterioration. Although Kuzbass (Siberia) is one of the largest exploited coal basins worldwide,...

Open AccessBlack carbon footprint of human presence in Antarctica
Black carbon (BC) from fossil fuel and biomass combustion darkens the snow and makes it melt sooner. The BC footprint of research activities and tourism in Antarctica has likely increased as human presence in ...

Open AccessPersistent extreme ultraviolet irradiance in Antarctica despite the ozone recovery onset
Attributable to the Montreal Protocol, the most successful environmental treaty ever, human-made ozone-depleting substances are declining and the stratospheric Antarctic ozone layer is recovering. However, the...

Open AccessEvaluation of MODIS-derived estimates of the albedo over the Atacama Desert using ground-based spectral measurements
Surface albedo is an important forcing parameter that drives the radiative energy budget as it determines the fraction of the downwelling solar irradiance that the surface reflects. Here we report on ground-ba...

Open AccessWarming events projected to become more frequent and last longer across Antarctica
Summer temperatures are often above freezing along the Antarctic coastline, which makes ice shelves and coastal snowpacks vulnerable to warming events (understood as periods of consecutive days with warmer tha...

Open AccessContaminant emissions as indicators of chemical elements in the snow along a latitudinal gradient in southern Andes
The chemical composition of snow provides insights on atmospheric transport of anthropogenic contaminants at different spatial scales. In this study, we assess how human activities influence the concentration ...

Open AccessDry-Season Snow Cover Losses in the Andes (18°–40°S) driven by Changes in Large-Scale Climate Modes
The Andean snowpack is the primary source of water for many communities in South America. We have used Landsat imagery over the period 1986–2018 in order to assess the changes in the snow cover extent across a...
