IRIS EMC Model Velocity Trend Viewer
The IRIS EMC Model Velocity Trend Viewer plots velocity values for a selected model as a function of depth at up to 4 locations (latitude-longitude pairs). Horizontal-axis shows the percent velocity perturbation. If a requested location does not fall on a model grid point, then the values for that location are derived from the 3 closest grid points using simple inverse distance weighting. If necessary, a simple inverse distance weighting is also used to interpolate profile's end depth points.
Use the companion interactive Google Map to select the points and see the area covered by the selected model.
