Data Services Products: EMC-MEAN A velocity reference Earth model for EAV09_SV

Summary

MEAN reference Earth model is based on the Earth model IASP91. MEAN replaces IASP91’s mid-crustal discontinuity and Moho depth of 20 and 35 km to 18 and 30 km, respectively.

Short Description   MEAN reference Earth model is based on the Earth model IASP91. MEAN replaces IASP91’s mid-crustal discontinuity and Moho depth of 20 and 35 km to 18 and 30 km, respectively. It also replaces IASP91’s a high S-velocity zone of the uppermost mantle (to the depth of 210 km) with a low S-velocity zone less than 4.5 km/s.
