  The full exploitation of the increasingly precise LHC measurements is
essential in order to reduce the uncertainty of theoretical predictions at
hadron colliders. The NNPDF2.3 fit was the first PDF determination including
the effect of the early LHC data. Here the new NNPDF3.0 PDF set is announced
and its main features are presented. The novel NNPDF analysis is based on an
improved fitting methodology, statistically validated by closure tests. Over a
thousand new data points are included, both the recent HERA II measurements and
a wide set of new LHC data. In this contribution details on the experimental
data are given and their impact on PDF uncertainties is displayed.
