lidar at night

The observatory is located at 51.7748°N, 0.0948°W at a rural, relatively unpolluted site near Hertford, 30 km north of the centre of London.

all-sky cameraRemote sensing instrumentation currently installed at the Observatory includes a Cimel CE 370-2 micropulse lidar on a scanning mount, daytime and night-time all-sky cameras,  a Cimel CE-318 automatic sun photometer - with data processed and curated by the NASA AERONET network (see video), a similar lunar photometer, a GNSS-based water vapour column measuring system, two IR radiometers including a Nubiscope scanning radiometer, a pyranometer and a pyrgeometer for measuring downwelling broadband solar and infrared radiation, respectively. Plots showing recent readings, including weather data, can be found on the weather page.

Two optical polarimeters are installed. The first polarimeter is an infra-red spectropolarimeter, with a view angle of 60°. The second, an ultra-sensitive sun polarimeter, is a portable version of the PlanetPol polarimeter, capable of measuring fractional polarization down to one part per million. PlanetPol previously detected the alignment of atmospheric dust.polarimeter

The Remote Sensing Observatory is co-located with the Astronomy Observatory, operated by the School of Physics Astronomy and Mathematics, which includes several telescopes equipped with CCD cameras and/or spectrographs and instruments for solar observations, such as a coelostat. Some of the research projects carried out at the observatory are described on the Research at Bayfordbury Observatory page.
