Meteorological Observing Systems Mini Conference 2024

On 12 September 2024, the University of Reading hosted the inaugural Meteorological Observing Systems Mini Conference, organised by the Royal Meteorological Society's Meteorological Observing Systems Special Interest Group (SIG). The event took place at the Department of Meteorology and welcomed around 60 amateur and professional meteorologists to discuss advancements in meteorological instruments both in the room and online. The day began with a warm welcome by Steve Colwell (Chair of the Meteorological Observing Systems SIG, BAS) and Keri Nicoll (University of Reading). The first session focused on instrument development, featuring three insightful presentations. Paul Stevens (Voltitude Ltd) kicked off the session with a talk on using stratospheric platforms for targeted observations over remote regions. Paul highlighted the innovative use of dropsondes, which are deployed from high-altitude platforms to gather valuable atmospheric data. Subsequently, Giles Harrison (University of Reading) introduced a miniature solar radiation data logger designed for balloon-based measurements, emphasising its efficiency and cost-effectiveness. Karen Aplin (University of Bristol) concluded the session with her presentation on a balloon-borne radioactivity detector, which measures space weather and atmospheric ionisation. After a brief refreshment break, the conference resumed with the second session on meteorological applications. Phil Rosenberg (NCAS) presented the Wessex Convection Experiment (WesCon1), detailing the instrumentation used to study pre-convective and post-convective situations in Wessex. Robert Plant (University of Reading) then discussed the importance of wind sensor averaging times for predicting short-range dispersal, providing insights into the accuracy of current models. Bruce Ingleby (ECMWF) explained the use of SYNOP data and its impact on weather forecasting, while Marwa Almowafy (University of Bath) explored the vertical wavelengths of gravity waves that drive the Quasi-Biennial Oscillation (QBO). Mike Molyneux (Met Office) wrapped up the session with a presentation on the WMO Global Surface Reference Network,2 highlighting the initial steps taken in the UK to ensure high-quality meteorological measurements at two chosen reference stations (Rothamsted and Camborne). A buffet lunch provided a break and an opportunity for attendees to network and discuss the morning's presentations. The afternoon session focused on atmospheric electricity, beginning with a talk by Graeme Marlton (Met Office) on lightning detection at the Met Office. Graeme explained the importance of accurate lightning data for aviation safety and flood warnings. Blair McGinness (University of Reading) followed with an evaluation of point discharge sensors, which measure atmospheric electricity and are particularly useful in harsh environments. Caleb Miller (University of Reading) presented on vertical profiles of atmospheric electricity and cloud properties in fog, using a tethered balloon platform. Finally, Keri Nicoll (University of Reading) introduced the use of unmanned aircraft for charged aerosol research, highlighting the potential of unmanned aerial vehicles (UAVs) in atmospheric studies. The conference concluded with a poster session and refreshments, allowing attendees to delve deeper into specific topics. Posters included presentations by Sharon Jewell (Met Office) on the impact of marine observations on global numerical weather prediction and Matthew Fry (Met Office) on the evaluation of stratospheric dropsonde data. Overall, the Meteorological Observing Systems Mini Conference provided a valuable platform for sharing knowledge and fostering collaboration among meteorologists. The diverse range of presentations and discussions highlighted the ongoing advancements in meteorological instrumentation and their applications in weather forecasting and atmospheric research. Following the first Meteorological Observing Systems Mini Conference, the Meteorological Observing Systems SIG is planning the 2025 edition, to be hosted by the University of Newcastle on 3 September 2025.
