The Earth models presented here are contributed to the IRIS Earth Model Collaboration
(EMC) by various researchers.
Two general types of model are available for download:
Tomography Models:
The contributed Earth models in their original format and in a common
netCDF (network Common Data Form). A model overview page provides a
summary of the model.
Reference Models:
Most EMC Earth models are expressed as perturbations relative to a
particular reference 1-D model. These reference models are available for
download in expanded comma separated value (CSV) file format with the
first two lines representing the file’s header.
For model visualization and additional information about the models visit the
IRIS EMC Product Page.
