EOFS

Syntax:

Field
{Y cosd}[X Y][T]svd

Example:

  • First EOF normalized structure of SST anomalies

  • Second EOF normalized structure of SST anomalies

  • First EOF "energy-containing" structure of SST anomalies

  • Normalized eigenvalues of SST anomalies

  • Singular values of SST anomalies

  • First EOF time series of SST anomalies

    • Troubleshooting:

    Will not work if data is too large. Need to cut in space or time.

    Please see the Ingrid statistical analysis tutorial on SVD for more information here.

    Don't worry if this takes a long time for the ingrid browser to process if working with a global grid and/or a long time period.

    EOF number is located in grid ev. Can select ev by VALUE, VALUES, or RANGE.

    Weighting factor {Y cosd} counts points near the equator more than points near the pole.
