Prospect for cosmological parameter estimation using future Hubble
  parameter measurements
  We constrain cosmological parameters using only Hubble parameter data and
quantify the impact of future Hubble parameter measurements on parameter
estimation for the most typical dark energy models. We first constrain
cosmological parameters using 52 current Hubble parameter data including the
Hubble constant measurement from the Hubble Space Telescope. Then we simulate
the baryon acoustic oscillation signals from WFIRST (Wide-Field Infrared Survey
Telescope) covering the redshift range of $z\in [0.5, 2]$ and the redshift
drift data from E-ELT (European Extremely Large Telescope) in the redshift
range of $z\in [2,5]$. It is shown that solely using the current Hubble
parameter data could give fairly good constraints on cosmological parameters.
Compared to the current Hubble parameter data, with the WFIRST observation the
$H(z)$ constraints on dark energy would be improved slightly, while with the
E-ELT observation the $H(z)$ constraints on dark energy is enormously improved.
