Abstract. The Convective Storm Initiation Project (CSIP) took place during the summers
of 2004 and 2005, centred on the research radar at Chilbolton, UK.
Precursors to convective precipitation were studied, using a comprehensive
and broad-based range of fieldwork and modelling. The principal aim of CSIP
was the detection of the primary and secondary initiation of convective
cells. The Universities Facility for Atmospheric Measurements (UFAM) Cessna
182 was used to map temperature and humidity fields over a broad area within
and beyond the Chilbolton radar beam. Additionally, air motion was measured
using a new turbulence probe, the AIMMS20AQ. The performance of the probe is
critically appraised, based on calibrations, test flights and data flights
flown during CSIP intensive operating periods. In general, the probe
performed well, although some aspects require more careful data
interpretation which we describe in detail.
