OKEMAP

EMAP dataset from Oklahoma plus four (4) perpendicular strike MT sites.

The EMAP data consists of ninty-three (93) dipoles at an angle of approx. N51E. The e-field measurements are all in-line (Ex), there are no cross-line measurements. The data available are the Zxx and Zxy responses in the range 384 Hz to 1820 s (Phoenix frequency set, as is COPROD2 and BC87).

The data are stored in both J-format and EDI format They are stored in zip compression format.

The data were used for examination at the second MT data interpretation workshop, MT-DIW2.

If you use these data in a publication, please inform me so that I can add it to the list below.
