Figure 8

Pressure feature (left column) and significance (right column) from January 15 to January 20, measured with (top to bottom) POLA-01, POLA-03 and POLA-04 sensors, respectively. The Gaussian-like feature corresponds to \(\sigma = 8\) min. The yellow, orange and green horizontal lines show the 3, 4 and 5 global significance sigma, respectively. The dotted line corresponds to the simulation data of Ref.4.
