EmanueleChangingFilters0 - Many different kinds of analyzes are performed for surface glaciology. Besides the direct samples of snow taken from the ground, there's also several pumps taking in outside air and the few crystals of ice it contains. Those crystals are then sorted by dimensions through an impactor filter, and later analyzed for content. The quantity of crystals in the atmosphere is so low that each pumping session has to run for 3 days non-stop, hoping that the wind won't turn and bring smoke from the station's power plant.

MeasuringPoles2 - The height of snow is measured precisely because the yearly snow accumulation on the high plateau is only a few centimeters, and most of the snow falls in winter while in summer it tends to sublimate. Actually the snow doesn't fall in the common sense of the term as much as it just 'appears' in a solid state condensation process directly on exposed surfaces. The lidar helps determine how much snow is falling in the form of very thin ice crystals.

PlaceMarkers - One in a series of several surface markers used to regularly measure the movement of the ice. Dome C is defined as the top of the local ice, but it's so flat that it's easier to define it as the place from which the ice flows in every direction, which is more interesting to deep drilling glaciologists. The station is visible far away on the horizon from this reference pole used yearly by specialized GPS equipment to pinpoint to flow of ice to within a few cm a year horizontally.
