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

The data includes the three-dimensional slab temperature field (degrees Celsius), water content (wt%), dehydration rate (wt%/km), and subduction velocity field (cm/yr) of the subducting Pacific plate, as well as the coastline and volcano distribution in southern and southwestern Alaska. The data coordinates are an orthogonal coordinate system, where the origin of the coordinates is (155.00W, 54.90N), the x+ azimuth is 150 degrees clockwise from the north, the y+ azimuth is 60 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 to analyze the geophysical field of the subduction zone. File naming: the data is stored in text paraview format. Data reading method: All ASCII code files in the data set can be directly opened with paraview software. Data list: 1. paraview_eq_USGS.vtk (Earthquake Catalog by IRIS, 2000-2010, Trabant et al., 2012, http://ds.iris.edu/ieb/) 2. paraview_map.vtk (global coastlines, GMT, Wessel and Smith, 1998) 3. paraview_slab.vtk (3-D thermal regime, slab water content, and slab dehydration) 4. paraview_volcano.vtk (global volcanoes at NCEI, Siebert et al., 2010)本数据集涵盖俯冲太平洋板块的三维板片温度场（单位：摄氏度）、含水量（质量百分比，wt%）、脱水速率（单位：wt%/km）以及俯冲速度场（单位：cm/yr），同时包含阿拉斯加南部与西南地区的海岸线及火山分布数据。 该数据集采用正交坐标系，坐标原点为(155.00W, 54.90N)，x轴正方向为从正北顺时针偏转150度，y轴正方向为从正北顺时针偏转60度，z轴正方向为垂直向下，单位为千米。 本数据集通过三维有限差分数值模拟方法生成，所有地球物理计算均在俯冲热状态达到稳态后完成。其中温度场误差范围为±50摄氏度，速度场误差范围为±0.1cm/yr。 本数据集可进一步用于俯冲带地球物理场的分析研究。 文件存储格式：数据以Paraview文本格式存储。 数据读取方式：数据集中所有ASCII编码文件均可直接通过Paraview软件打开。 数据集文件列表： 1. paraview_eq_USGS.vtk：（IRIS发布的地震目录，2000-2010年，Trabant等，2012，http://ds.iris.edu/ieb/） 2. paraview_map.vtk：（全球海岸线数据，GMT，Wessel与Smith，1998） 3. paraview_slab.vtk：（三维热状态、板片含水量及板片脱水过程数据） 4. paraview_volcano.vtk：（NCEI收录的全球火山数据，Siebert等，2010）
