Imagery
of micro-structures of firn snow and ice
I
have developed image processing based on Image Processing
Software (http://pageperso.lif.univ-mrs.fr/~edouard.thiel/ips/)
to measure snow grains size, analyzing micro-structure of
firn and ice for the purpose of obtaining descriptors of
these objects. These parameters were implemented in 3 physical models, a first model of firn densification, a second of pore closure and a third of gas diffusion. They have also been used to improve the laws of grain growth in ice.
