Abstract: We develop formalism based on the projected Gross Pitaevskii equation tosimulate the finite temperature collective mode experiments of Jin et al. PRL78, 764 1997. We examine the $m=0$ and $m=2$ quadrupolar modes on thetemperature range $0.51T c-0.83T c$ and calculate the frequencies of, and phasebetween, the condensate and noncondensate modes, and the condensate modedamping rate. This study is the first quantitative comparison of the projectedGross-Pitaevskii equation to experimental results in a dynamical regime.
