For the second winter of measurements at Col de Porte, the snow arrived quite late beginning of January and did not stay for long. However, we manage to perform numerous measurements using several instruments (see Figure below). During this field campaign, we add several objectives :

• The intercomparison of SSA measurements from several instruments (SMP, CTscanner, HISSGRASS and DUFISSS)
• The monitoring of the snowpack with high and low resolution CT scans
• The development of a novel method to analyse low resolution CT scans to estimate snow density and SSA.
