Estimating Snow Grain Size Using AVIRIS Data
Es t ima te s of snow grain size for the near-surface snow layer were calculated for the Tioga Pass region and Mammoth Mountain in the Sierra Nevada, California, using an inversion technique and data collected by the Airborne Visible/Infrared Imaging Spectrometer (A VIRIS). The inversion method takes advantage of the sensitivity of near-infrared snowpack reflectance to snow grain size. The Tiog...
متن کاملMapping Snow Grain Size over Greenland from MODIS
This paper presents a new automatic algorithm to derive optical snow grain size (SGS) at 1 km resolution using Moderate Resolution Imaging Spectroradiometer (MODIS) measurements. Differently from previous approaches, snow grains are not assumed to be spherical but a fractal approach is used to account for their irregular shape. The retrieval is conceptually based on an analytical asymptotic rad...
متن کاملSnow Cover
Snow cover is a layer of snow on the earth’s surface, which is mainly results from snowfalls. The snow cover can be temporary, when a snow melts during several hours or days after its formation, and it can be stable, when it remains for the whole winter or with short interruptions. The snow cover formation on the globe is determined (conditioned) by the geographical zonality, surface relief, an...
متن کاملA Hyperspectral Method for Remotely Sensing the Grain Size of Snow
We have developed a robust, accurate inversion techare useful indicators of thermodynamic processes in the snowpack. Changes in snow grain size can help identify nique for estimating the grain size in a snowpack’s surface ice sheet surface features, such as melt areas, snow dunes, layer from imaging spectrometer data. Using a radiative and blue ice regions, and often indicate changes in snowtra...
متن کاملA New Method for Sub-pixel Snow-cover Mapping Using Hyperspectral Imagery – First Results
Most methods applied for snow-cover mapping classify each pixel into snow and no-snow. On the other side, a sub-pixel method classifies snow into several coverage classes or onto a continuous scale. If frequent mapping is required, only low and medium spatial resolution sensors are available (200-1000 m range). Classifying pixels into snow and no-snow only may be sufficient for largescale appli...
