Network Outage


Starting around 2017-02-17 16:20 UTC (11:20 EDT / 8:20 PDT) IRIS Data Services experienced a network outage. We are still looking into the cause of the outage and hope to be back online as soon as possible. We apologize for the inconvenience to your workflow.

Earth Models

CESM The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth’s past, present, and future climate states.
CUB CUB Upper Mantle Shear Velocity Model Earth Reference Data and Models
EGM Earth Gravitational Model
ESRM European Seismological Reference Model
GERM Geochemical Earth Reference Model
GMT Global Mantle Tomography
REM Reference Earth Model


GEON IDV For 3D exploration and comparisions of seismic tomography
KML Generator A quick visual image of seismic tomographic models via Google Earth
MET The Model Evaluation Tools (MET) verification package was developed by the National Center for Atmospheric Research (NCAR) Developmental Testbed Center (DTC) is designed to be a highly-configurable, state-of-the-art suite of verification tools. It was developed using output from the Weather Research and Forecasting (WRF) mod eling system but may be applied to the output of other modeling systems as well
OEF The Open Earth Framework (OEF) is a visual analytics suite of software libraries and applications that assist in the analysis, visualization, and integration of large multi-dimensional multi-disciplinary geophysical and geologic data sets
Tomoeye A set of programs for tomographic model visualization written in MatLab 6.1 script

Data Tools

ncBrowse A Graphical netCDF File Browser
NCO The netCDF Operators (NCO) comprise a dozen standalone, command-line programs for operating on netCDF files
ANDX ANDX (formerly known as NCDX) is a command-line utility designed for routine examination and extraction of data from netcdf files
