  A FRAM (F/(Ph)otometric Robotic Atmospheric Monitor) telescope is a system of
a robotic mount, a large-format CCD camera and a fast telephoto lens that can
be used for atmospheric monitoring at any site when information about the
atmospheric transparency is required with high spatial or temporal resolution
and where continuous use of laser-based methods for this purpose would
interfere with other observations. The original FRAM has been operated at the
Pierre Auger Observatory in Argentina for more than a decade, while three more
FRAMs are foreseen to be used by the Cherenkov Telescope Array (CTA). The CTA
FRAMs are being deployed ahead of time to characterize the properties of the
sites prior to the operation of the CTA telescopes; one FRAM has been running
on the planned future CTA site in Chile for a year while two others are
expected to become operational before the end of 2018. We report on the
hardware and current status of operation and/or deployment of all the FRAM
instruments in question as well as on some of the preliminary results of
integral aerosol measurements by the FRAMs in Argentina and Chile
