Mobile X-Band Radar
The mobile radar operates at X-band (9.375 GHz, 3cm) and has Doppler and dual-polarisation capability. The radar measures areal precipitation, radial winds and polarisation parameters. It can also detect clear-air echoes at close range from insects. The system has a conventional parabolic antenna of 2.4m diameter and a beamwidth of 1 degree, operated without a radome. The radar is fully transportable, being mounted on a trailer approved for EU roads that can be towed by a 4x4 vehicle.
Signal analysis, data retrievals and data storage are performed by PCs contained within the trailer unit. The radar can be operated via a laptop that connects by wireless, ethernet or 3G to the onboard PCs. The operational software allows the user to set up the radar for deployment and schedule the scanning sequence. The software also provides real-time data visualisation and product generation.

Instrument Data Archive Name: The instrument name is used in the generation of the file names for the data files that are archived on CEDA. The names used do not always appear logical and this is for historical reasons. This instrument is referred to as ncas-mobile-xband-radar.
Applications: This instrument has a wide range of applications including: dynamics of convective storms and extra-tropical cyclones; cloud microphysics; deep tropical convection; boundary layer structures such as convergence lines and sea-breezes; hydrology; urban rainfall.
Keywords: radar, precipitation, rainfall, dual-polarisation, Doppler, clouds, microphysics, clear-air echoes, convection, storms, dynamics, rainfall.
Instrument Operational Category: This is an AMF category 6 instrument indicating that the instrument is under development, testing and assessment. No AMF data products are available for instruments in this category. The Value Added Data (VAD) products offered are developmental and subject to frequent changes as our confidence in the validity of the data produced increases. See the Instrument Scientist support page for a full description of the support options available.
