working principle:
Specific surface area of snow（the specific surface area(abbreviationSSA) of snow）Defined as the surface area of ice and snow per unit mass, it is an important variable in the microstructure of snow (which plays a crucial role in determining the chemical pollution and climate impact on snow)
The infrared hemisphere reflection of snow andSSAThe relationship between reflections isice cubeBased on the working principle. The snow sample is directly emitted by a laser diode1310Nano based quasi direct light analysis. The light reflected by snow is collected by an integrating sphere of indium gallium arsenide light-emitting diode and converted into voltage. Then, a calibration curve obtained through certified standards provides the relationship between signal and reflectance. This reflectance is then calibrated using a radioactive conversion model and methane absorption method, and then converted intoSSA
