Ross Ice Shelf

Sketch (not to scale) of GNSS sensitivity to atmospheric turbulence in Antarctica. GNSS stations can probe the spatiotemporal distribution of water vapor in the lower atmosphere because water vapor induces a measurable signal propagation delay. Water-vapor distribution is spatially homogeneous for a non-turbulent atmosphere and heterogeneous when the atmosphere is turbulent. (Credit: MIT)
