Recently time series spectroscopy of hydrogen atmosphere white dwarfs (DAVs) has proven successful in measuring the spherical degree and pulsation velocity of each mode. The information gained from these observations would be enhanced by having the observations coincide with a multi-site photometry, such as that provided by a Whole Earth Telescope (WET). The accurate photometry would provide the precise periods and photometric amplitudes that cannot be easily obtained by spectroscopy alone. Combining spectroscopy with photometry of DAVs will lead to answers regarding combination modes, convective driving, and the pulsation geometry of each mode. Here I discuss how time series spectroscopy will improve the results of the photometric runs and the quality and quantity needed for success.
