Lateral Variations in Upper Mantle Discontinuities beneath Northeast China Revealed by Seismic Ambient Noise

Description

Data description:
 
CCdata.zip:
Re-sampling Cross-Correlation functions (4Hz) which contain three seismic arrays.
CEA contains HL, JL, LN and NM networks. 
NECESSarray contains YP network. NECsaids contains DB network. 
All the stations are located east of 122E, between 41N and 46N. 
The cross-correlations are used to retrieved body-wave reflections from mantle transition zone discontinuities.
 
Syntheticdata.zip:
contains four parts: rawdata1d, rawdata2d, stackedwaveform-2d, and compare-1d
 
rawdata1d: 
raw synthetic waveforms calculated by Qseis (Wang, 1999) after data-processings.
H is increased from 0 to 30 km. 
The distance is 100 km.  
 
rawdata2d: 
raw synthetic waveforms calculated by SPECFEM2D (Tromp et al., 2008).
Three models with depressed d660 (model 1-3) and with a slab on the d660 (model 4).  
100 receiver stations (surface), from 305 km to 1295 km in 10 km increments.
49 vertical single-force sources (surface), from 320 km to 1280 km in 20 km increments 
 
stackedwaveform-2d:
The final depth results with different models.
 
compare-1d:
The waveforms used to compare the rf and cc.
 
Code:
These codes can be used to make the figures of synthetic and NCFs results.
