Using a handheld integrating sphere snow grain sizer (HISSGraS), which directly measures the snow surface without sampling, we collected 215 sets of SSA data, with each set comprising measurements from 10 surfaces along a 20 m transect. The measured SSA shows no elevation or ...
Surface area-equivalent diameter(等表面积当量直径)ds 假定一球形颗粒具有与被考察颗粒相同的表面积,则该球形颗粒的直径即为被考察颗粒的等表面积当量直径 ds: Where Sp =?surface area?of?the?particle The surface area-equivalent diameter, ds, is defined as the diameter of a sphere having the same ...

The specific surface area (SSA), defined as the surface area per unit mass, is a key variable to describe the physical properties of snow. It is seen as an objective, reliable and physically meaningful size metric for snow grains and can be a very good replacement of more conventional snow...
The results show that humic acid could increase the specific surface area and change the crystal morphology at the same time. Morphology of the calcium carbonate fine particles graduated from sphere-like into rod-like, and then into cubic-like shape. A proposed mechanism based on the results of...
