Tl. Duvall et L. Gizon, Time-distance helioseismology with f modes as a method for measurement of near-surface flows, SOLAR PHYS, 192(1-2), 2000, pp. 177-191
Travel times measured for the f mode have been used to study flows near the
solar surface in conjunction with simultaneous measurements of the magneti
c field. Previous flow measurements of Doppler surface rotation, small magn
etic feature rotation, supergranular pattern rotation, and surface meridion
al circulation have been confirmed. In addition, the flow in supergranules
due to Coriolis forces has been measured. The spatial and temporal power sp
ectra for a six-day observing sequence have been measured.
