The optical properties of snow can be strongly modified by the presence a variety impurities including mineral dust and algae. We made use measured concentration algae to parameterize BioSNICAR radiative transfer model. Surficial samples were gathered during field campaign on 7th July 2020 at Presena glacier (Rhaetian Alps). collected 18 surface containing different amount dust. Through simulations we estimated an average broadband albedo reduction 7.4±6.1% % 35.3±7.4% compared clean snow,...
We describe an optical approach based on Digital Holography for single-particle characterization of mineral dust and micrometric particles, focusing the analysis airborne particles in meltwater from Antarctic ice cores. record holograms formed by superposition transilluminating reference beam waves scattered single particles. Taking a cue recent approaches field holography methods, we process to recover both morphological properties grains. As considerable advantage over traditional...
We propose a compact, portable, and low-cost holographic microscope designed for the characterization of micrometric particles suspended in liquid. This system is built around commercial optical by substituting its illumination source (a light-emitting diode) with collimated laser beam. Similarly, quartz flow cell replaces glass slide using 3D-printed custom mount. With hardware presented this paper, imaging electromagnetic fields emitted that intercept beam achieves resolution close to...
The main objective of the project SCIA (Sviluppo di algoritmi per lo studio della Criosfera mediante Immagini PrismA) is development and optimization methods for generating products related to cryosphere. foresees a robust processing chain PRISMA hyperspectral data estimation snow glacier parameters in Alpine areas, through combined use satellite images, field radiative transfer models (RTMs). image spectroscopy measurements provided by will make possible investigate radiometrically complex...
Mineral dust aerosol plays an important role in climate and biogeochemical processes by providing nutrients to marine terrestrial ecosystems influencing the radiation balance of atmosphere. In turn, mineral responds natural anthropogenic alterations land cover use resulting from several environmental changes that occurred on different timescales. Contamination aerosols is a very tangible threat cryosphere European Alps due its proximity highly urbanized areas, cultivated landscapes, largest...
The spectral reflectance of snow and ice varies widely depending on several quantities related (1) to the local environmental variables, such as solar zenith angle surface slope, (2) physical properties snow, grain size liquid content, (3) presence light-absorbing particles (LAPs).  Different absorption features are displayed in spectra. In particular, at 1030 nm has been exploited for estimating effective radius both from remote proximal sensing data (Dozier et al., 2009, Garzonio...
<p>There is much information to be derived from the airborne dust that can found in ice cores, especially about aerosol composition and sources, including characteristics of atmosphere several thousands years ago. There is, fact, still learn both data retrieved how interpret them with appropriate models. One most striking aspects these tiny particles effect their shape alone has on scattering absorption properties, which translate into a contribution Earth radiative transfer,...
