Geomagnetically trapped antiproton spectrum measured by PAMELA in the SAA region. The error bars indicate statistical uncertainties.Trapped antiproton predictions by Selesnick et al. (2007) for the PAMELA satellite orbit, and by Gusev et al. (2008) at L = 1.2, are also reported. For comparison, the mean atmospheric under-cutoff antiproton spectrum outside the SAA region and the galactic CR antiproton spectrum measured by PAMELA are also shown

Trapped antip/p ratio measured by PAMELA in the SAA region. Results are compared with predictions by Selesnick et al. (2007).The galactic CR antip/p ratio PAMELA data are also reported
