The HATPRO Radiometer is a system which is passive with two frequency reception bands: 22-31 GHz (7 channel filter bank humidity profiler and LWP radiometer) and 51-58 GHz (7 channel filter bank temperature profiler). 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).
