Air pollution in New York City linked to wildfires hundreds of miles away
- Press release
- 21 January 2020
A new study published in the European Geosciences Union (EGU) journal Atmospheric Chemistry and Physics shows that air pollutants from the smoke of fires from as far as Canada and the southeastern U.S. traveled hundreds of miles and several days to reach Connecticut and New York City, where it caused significant increases in pollution concentrations.

Surface water as a cause of land degradation from dryland salinity
- Hydrology and Earth System Sciences
- DOI 10.5194/hess-24-717-2020
- 25 February 2020
Secondary dryland salinity is a global land degradation issue. Our understanding of causal processes is adapted from wet and hydrologically connected landscapes and concludes that low end-of-catchment runoff indicates land clearing alters water balance in favour of increased infiltration and rising groundwater that bring salts to the surface causing salinity. This study shows surface flows play an important role in causing valley floor recharge and dryland salinity in low-gradient landscapes.
Cryoconite: an efficient accumulator of radioactive fallout in glacialenvironments
- The Cryosphere
- DOI 10.5194/tc-14-657-2020
- 25 February 2020
Cryoconite is the sediment found on the surface of glaciers. The paper presents cryoconite as an environmental matrix able to accumulate natural and artificial radioactivity with unprecedented efficiency. Only samples from sites where nuclear accidents and explosions occurred present a stronger radioactive contamination. The peculiarities of glacial environments are responsible for this extreme feature, making cryoconite a useful tool tool for the monitoring of environmental radioactivity.
Quantifying hail size distributions from the sky – application of drone aerial photogrammetry
- Atmospheric Measurement Techniques
- DOI 10.5194/amt-13-747-2020
- 25 February 2020
Collecting measurements of hail size and shape is difficult due to the infrequent and dangerous nature of hailstorms. To improve upon this, a new technique called HailPixel is introduced for measuring hail using aerial imagery collected by a drone. A combination of machine learning and computer vision methods is used to extract the shape of thousands of hailstones from the aerial imagery. The improved statistics from the much larger HailPixel dataset show significant benefits.
A multi-model analysis of teleconnected crop yield variability in a range of cropping systems
- Earth System Dynamics
- DOI 10.5194/esd-11-113-2020
- 20 February 2020
In this study, we analyse the impacts of three major climate oscillations on global crop production. Our results show that maize, rice, soybean, and wheat yields are influenced by climate oscillations to a wide extent and in several important crop-producing regions. We observe larger impacts if crops are rainfed or fully fertilized, while irrigation tends to mitigate the impacts. These results can potentially help to increase the resilience of the global food system to climate-related shocks.

Satellite soil moisture improves rainfall just where needed
- Natural Hazards
- posted 1 day ago
Soil moisture and rainfall are the two fundamental variables in the water and energy cycle and their knowledge in many applications is crucial. For instance, for predicting the occurrence and the magnitude of flood and landslide events the knowledge of the initial soil moisture condition and of rainfall amount is mandatory. In the last decade, some authors have proposed a completely new approach, i.e., the use of satellite soil moisture for estimating and improving rainfall, doing hydrology backwards. In 2014, …
