DIT_PhilippineSea: Vertical displacements of the thermocline induced by diurnal internal tides (DITs) from in-situ PIES measurements and ray path of the DITs by using two dimensional ray-tracing

This repository contains internal tide data needed to reproduce the results in the Journal of Geophysical Research: Oceans article "Warm Eddy Effects on the Refraction of Diurnal Internal Tides in the Northwestern Pacific from PIES Observations" by K. N. Lee, J. H. Park, C. Jeon, H. S. Min, C. Lee, S. Park, X. H. Zhu, C. Zhang, and Z. Zhao.This dataset includes vertical displacements of the thermocline (∆Zτ) induced by diurnal internal tides (DITs) in the eastern Philippine Sea (16.3°–18°N and 139.5°–142°E), as well as DIT ray path information obtained using two-dimensional ray-tracing. ∆Zτ was derived from measurements by 10 PIES (pressure-recording inverted echo sounders) deployed from 2020 to June 2021. The DIT variable consists of one row with date number (counted from January 1, 0000) and another row with corresponding ∆Zτ values. The mean ray paths of the DITs were calculated over 150 hours at 3-month intervals. The initial ray crest line was assumed to have a slope of 90 degrees and consisted of 12 points spaced 35 km apart.
