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)
