  We present the preliminary analysis of over 1739 known and 349 candidate
Jovian Trojans observed by the NEOWISE component of the Wide-field Infrared
Survey Explorer (WISE). With this survey the available diameters, albedos and
beaming parameters for the Jovian Trojans have been increased by more than an
order of magnitude compared to previous surveys. We find that the Jovian Trojan
population is very homogenous for sizes larger than $\sim10$km (close to the
detection limit of WISE for these objects). The observed sample consists almost
exclusively of low albedo objects, having a mean albedo value of $0.07\pm0.03$.
The beaming parameter was also derived for a large fraction of the observed
sample, and it is also very homogenous with an observed mean value of
$0.88\pm0.13$. Preliminary debiasing of the survey shows our observed sample is
consistent with the leading cloud containing more objects than the trailing
cloud. We estimate the fraction to be N(leading)/N(trailing) $\sim 1.4 \pm
0.2$, lower than the $1.6 \pm 0.1$ value derived by others.
