“…While most of the surface snow in the interior of the Antarctic Ice Sheet is uncontaminated, on the margins of the continent several processes occur and they can deposit or resurface light-absorbing particles, as observed in different studies (Dadic et al, 2013;Casey et al, 2017;Warren, 2019a;2019b;Kavan et al, 2020;Di Mauro et al, 2021;Gray et al, 2021;Cordero et al, 2022). Recent observation from the Antarctic Peninsula showed that surface snow may contain cryospheric algae (Gray et al, 2020(Gray et al, , 2021 and black carbon (Cordero et al, 2022).…”

In this paper, we made use of PRISMA imaging spectroscopy data for retrieving surface snow properties in the Nansen Ice Shelf (East Antarctica). PRISMA satellite mission has been launched in 2019 and it features 239 spectral bands covering the 400-2500 nm interval. These data are promising for cryospheric applications, since several snow and ice parameters can be derived from reflectance in the Visible Near InfraRed - Short Wave InfraRed (VNIR-SWIR) wavelength interval. Here we analyze, for the first time, PRISMA data collected in Antarctica. Our scene was acquired on December 2020 over the Nansen Ice Shelf (NIS). Using PRISMA data we estimated various snow parameters (effective grain diameter, snow specific surface area, snow spectral and broadband albedo, bottom of atmosphere snow reflectance, type of impurities in snow and their concentration), and we compared them with data presented in the scientific literature.

“…Surface and volume scattering governs ice reflection characteristics (Gardner & Sharp, 2010), and increasing ice thickness can increase the albedo (Grenfell & Perovich, 1984). An increase in pollutants content can weaken the ice reflection signature, similar to the effects of impurities in the snow (Di Mauro et al., 2021). Moreover, increasing bubbles and salt cell radius can enhance volume scattering intensity and increase ice reflection (Carns et al., 2015; Dadic et al., 2013).…”

Snow/ice plays a crucial role in the Earth's radiation balance, hydrological cycle, and climate change (Warren, 1982;. Relative to other land covers, snow/ice surface is more sensitive to natural conditions (e.g., temperature, precipitation, and solar azimuth), and its reflective characteristics can change more quickly on the spatio-temporal scale (Diner et al., 1999). The development of satellite-terrestrial observation technology in the past several decades has made it possible to realize globally continuous monitoring and inversion of physical parameters of snow/ice. Satellite sensors measure reflected radiance only in some particular directions. However, snow/ice surface is a non-Lambertian surface, and it is unreasonable to depict the reflection characteristics of snow and ice using a single direction observation (Li & Zhou, 2002). To this end, the Bidirectional Reflectance Distribution Function (BRDF) which describes the angular pattern of reflective light within hemisphere space, has crucial meaning for monitoring snow/ice variation and improving inversion precision of its physical parameters (Hudson et al., 2006).Basically, field observation offers the most accurate ways for obtaining BRDF of snow/ice and provides the basis of validation in model simulation and remote sensing inversion (Jiao et al., 2019;Knap & Reijmer, 1998). The anisotropy of snow/ice is sensitivity to a wide range of factors, for example, snow/ice states (

This research focuses on a bibliometric analysis of research on aerosols' impact on the glaciers in the Indian Himalayan region (IHR) published in journals from all subject categories based on the Science Citation Index Expanded, collected from the Web of Science and Scopus database between the years 2002 and April 2022. The indexing phrases like "aerosol," "glacier," and "snow" are commonly used terms and have been utilized to collect the related publications for this investigation. The document selections were based on years of publication, authorship, the scienti c output of authors, distribution of publication by country, categories of the subjects, and names of journals in which scholarly papers were published. The journal's impact factor trend, citation trend, and the count of keywords used by authors were also included. The number of articles on aerosols accelerating the melting of glaciers shows a notable increase in recent years, along with more glacier melting results from countries involved in climate science research. China (382) was the country with the highest publication output on aerosols accelerating the melting of glaciers. The United States (367) was the most cited country with about 17500 total citations and 80.40 average citations per year from 2002-April 2022. The results reveal that research trends in the glaciers on aerosols' impact on the glaciers have been attractive in recent years, and the number of articles in this eld keeps increasing fast.
