3-D data of thermal regime, water content, and slab dehydration in Central America

The data includes the three-dimensional temperature field (degrees Celsius), water content (wt%), dehydration rate (wt%/km), rock phase change distribution, and subduction velocity field (cm/yr) of the subducting plate, as well as the coastline and volcano distribution. The data coordinates are an orthogonal coordinate system, where the origin of the coordinates is (88.10W,10.70N), the x+ azimuth is 212 degrees clockwise from the north , the y+ azimuth is 122 degrees clockwise from the north , and the z+ direction is vertical downwards, in kilometers. The data source method is a three-dimensional finite difference numerical simulation. The geophysical calculation is ensured after the subduction thermal regime reaches a steady state. The temperature field error range is ±50 degrees Celsius, and the velocity field error range is ±0.1cm/ yr. This data can be further used analyzing the geophysical field of subduction zone.

File naming: the data is stored in text paraview format.
