Large-scale solid bodies on Earth such as volcanoes and man-made pyramids have been visualized with solid earth muography, and the recently invented technique, acqueous muography, has already demonstrated its capability to visualize ocean tides and tsunami. In this work, atmospheric muography, a technique to visualize and monitor the vertical profile of tropic cyclones (TCs) is presented for the first time. The density distribution and time-dependent behavior of several TCs which had approached Kagoshima, Japan, has been investigated with muography.

It was detected right after the arrival of the 2021 Typhoon-16 that passed through the region 400 km south of the bay. The measured oscillation period and decay time were respectively 3 h and 10 h.

- - Tidal measurements are crucial for protecting coastal communities and managing sea traffic, with traditional methods involving tide gauge stations and laser altimetry.
- - Researchers have deployed the Tokyo-bay Seafloor Hyper-Kilometric Submarine Deep Detector (TS-HKMSDD), the first under-seafloor particle detector array, to measure tidal levels via muography beneath the Tokyo Bay.
- - Analysis of 80 days of muographic data showed a 12.85 cm standard deviation from traditional astronomical tide height measurements, suggesting that extending the TS-HKMSDD could standardize muography as a reliable tidal monitoring method in busy waterways.
