A Lufft WS500 weather station is incorporated into the instrument to provide co-located meteorological measurements. Alternatively, particle mass concentrations can be produced as PM1, PM2.5 and PM10 measurements. The instrument measures the size and number density of aerosol molecules by using a 0.5m vertical inlet to suck ambient air into a measurement chamber. The scattering of a laser beam transmitted through the chamber is used to deduce size and concentration information. It is operated continuously on the roof of a cabin at a height of 8m above ground at the Chilbolton Observatory site. Measurements are taken every 60s, providing aerosol particle concentration (counts/m3) in 31 size bins in the range 0.265-34.0 um, air temperature, relative humidity, air pressure, wind speed and wind direction. The instrument is calibrated every 18 months by the manufacturer",

Internally-stored calibration data are used to convert these absorption values to a mole concentration for each gas. Carbon dioxde and water vapour mole concentrations from this instrument are also provided with sonic anemomenter data at a 20Hz data acquisition rate for eddy covariance calculations in another CFARR dataset.

A range of data are retrieved including: vertical profiles of atmospheric temperature; vertical profiles of relative and absolute humidity; liquid water path (LWP); integrated water vapour (IWV); stability indices; and surface pressure, temperature, relative humidity and rain flags. The system is capable of standalone operation but the AMF supply a host PC to facilitate data archiving and custom setup of the instrument. The HATPRO GPS provide the measurement timing and and also position. The environmental temperature range for operation: – 60°C to + 45°C and the automatic rain-mitigation system, consisting of a hydrophobic coating and strong blower, prevent rain settling on the radome. The 1.8kW heater module prevents formation of dew and fog condensation on radome. A new radome is fitted before any deployment and replaced, while on deployment, every 6 months or if compromised. (Mechanical damage, salt build up etc all result in the hydrophobic properties of the radome being compromised).",

Both systems are 400 MHz variants.\r\n\r\nAlthough now designated as NCAS AMF instruments they have each had previous designations with this unit previously been known as the \"Manchester/UFAM: Vaisala Radiosonde\" and represented by \"man-radiosonde\" in filenames.\r\n\r\nVaisala radiosonde systems are used by meteorological organizations all around the world to measure weather in the Earth’s atmosphere, from the boundary layer to the upper atmosphere. The radiosonde is a lightweight, balloon-borne instrument that measures profiles of pressure, temperature and humidity from the ground to approximately 40 km. The radiosonde is equipped with a radio transmitter for sending the measurements securely to the observing station. The user has control over the sounding process by integrating sounding controls, archiving the sounding data and meteorological message creation. For routine soundings the system offers a variety of features and allows the desired balance of manual and automatic control. In addition to the traditional alphanumeric messages, the system software produces the WMO specified BUFR messages. This feature enables users to follow the WMO's recommendation to move from traditional alphanumeric codes to binary BUFR codes.\r\n\r\nThis record also records the present and previous instrument scientists responsible for the equipment (recorded here as \"operators\") for historic purposes with the current instrument scientist given last. It is possible that other operators may use the equipment from time to time and these should be recorded as dataset authors for each associated datasets in the archive.",
