Conducting fieldwork in polar regions presents a multifaceted challenge not only because of the remoteness of the environment, but also potential geopolitical disputes, language barriers, divergent national policies, and disparities in emergency healthcare access. This review addresses the climate crisis and reevaluates the ethical considerations o...

Measurements of spectral zenith radiance in the 320–950 nm wavelength range have been carried out since 2021 at the Thule High Arctic Atmospheric Observatory (THAAO, https://www.thuleatmos-it.it/ , 76.5° N, 68.8° W, 225 m a.s.l) located in Pituffik, northern Greenland. This study evaluates whether such observations could provide, in principle, sci...

Ground-based high resolution observations of downward longwave irradiance (DLI), surface air temperature, water vapor surface partial pressure and column amount, zenith sky infrared (IR) radiance in the atmospheric window, and all-sky camera images are regularly obtained at the Thule High Arctic Atmospheric Observatory (THAAO, 76.5° N, 68.8° W), no...

The Arctic climate is influenced by the interaction of shortwave (SW) and longwave (LW) radiation with the atmosphere and the surface. The comprehensive evolution of the Surface Radiative Fluxes (SRF) on different time scales is of paramount importance to understanding the complex mechanisms governing the Arctic climate. However, only a few sites l...

Climate change is rapidly reshaping the research landscape in the polar regions. As such, Early Career Researchers (ECRs) face increasingly daunting challenges. In this opinion piece, we report on the challenges that early career researchers confront as they seek opportunities for professional development and career advancement in polar research in...

The relevance of the Arctic has become apparent in the last decades, and it is today widely agreed that this area is affected by fast and unavoidable changes taking place at the global and local scale. The Arctic environment is interesting from geopolitical, economic, and scientific perspectives, and the study of the natural components characterisi...

Clouds are one of the key components of the Earth System still requiring further understanding. The complexity of the cloud itself and the different interactions with aerosol and radiation cause large uncertainties in the estimation of the cloud feedback in climate models. Processes involving clouds are particularly relevant at high latitudes, wher...

The Arctic radiative budget is strongly influenced by cloud variability and properties, and many processes of cloud formation-evolution-dissipation still require a more extensive and deeper understanding. The spectral signature of clouds, i.e., the radiances, can be measured and used to discriminate the microphysics of clouds (optical thickness, pa...

Boreal fires have increased during the last years and are projected to become more intense and frequent as a consequence of climate change. Wildfires produce a wide range of effects on the Arctic climate and ecosystem, and understanding these effects is crucial for predicting the future evolution of the Arctic region. This study focuses on the impa...

This study considers a set of state-of-the-art seasonal forecasting systems (ECMWF, MF, UKMO, CMCC, DWD and the corresponding multi-model ensemble) and quantifies their added value (if any) in predicting seasonal and monthly temperature and precipitation anomalies over the Mediterranean region compared to a simple forecasting method based on the ER...

Assessment of seasonal forecast skills...

Seasonal forecasts are increasingly employed as sources of information on the expected evolution of climate in the few months ahead by various end-users. This study provides an overall assessment of the skills of the main seasonal forecast systems available in the Copernicus Climate Data Store (C3S) in representing temperature and precipitation ano...

Extended and intense wildfires occurred in Northern Canada and, unexpectedly, on theGreenlandic West coast during summer 2017. The thick smoke plume emitted into theatmosphere was transported to the high Arctic, producing one of the largest impacts everobserved in the region. Evidence of Canadian and Greenlandic wildfires was recorded at the ThuleH...

Surface ablation of the Greenland ice sheet is amplified by surface darkening caused by light-absorbing impurities such as mineral dust, black carbon, and pigmented microbial cells. We present the first quantitative assessment of the microbial contribution to the ice sheet surface darkening, based on field measurements of surface reflectance and co...

Understanding climate variability and change demands for the assessment of extremes in climate such as cold spells, heat waves, intense precipitation among others.
