  The Spanish partners of the future Cherenkov Telescope Array (CTA) have
selected a candidate site for the Northern installation of CTA, at 3 km from
the Observatorio del Teide (OT), in the Canary Island of Tenerife. As the OT is
a very well-characterized astronomical site. We focus here on differences
between the publicly accessible measurements from the OT observatory and those
obtained with instruments deployed at the candidate site. We find that the
winds are generally softer at the candidate site, and the level of background
light comparable to the Observatorio del Roque de los Muchachos (ORM) at La
Palma in the B-band, while it is only slightly higher in the V-band.
