Ben Pickering is a postgraduate researcher studying hydrometeor classification (rain, snow, hail e.t.c) from the newly upgraded dual-polarisation UK radar network (C-Band, 5.60 – 5.65 GHz). Ben is focused on developing verification techniques for these categorical, discreet products. This will be achieved by developing a new framework of 'big data' observations: in-situ such as the FAAM aircraft, and ground-based observations like Met Office stations, crowdsourced weather reports and the newly installed Disdrometer Verification Network (DiVeN) for comparison. Ben developed the DiVeN network of 14 laser disdrometers in 2017 as part of his PhD work on radar verification which took several months and thousands of miles of travel around the UK to install.

Generally I am interested in observations of the atmosphere, which is an area we can, and must, improve upon in order to continue advances in weather forecasting. These advances are essential as humanity faces great societal changes with the climate emergency such as renewable energy forecasting and agricultural strains, and new industries like drones and autonomous vehicles. My interests can be broadly assigned to three areas:
Unmanned Aerial Systems (UAS / UAV, aka Drones)
I believe there is an emerging new field to be found in the development of UAS for meteorological uses. In particular, a vertically profiling instrumented UAS that can land, recharge and fly again without human interaction would provide sufficient data for next-gen numerical weather prediction, with significant enhancement of forecasts of the atmospheric boundary layer. This will enable greater accuracy of forecasts for solar and wind energy, air quality, fog, and will be essential for future UAS industries such as inner-city delivery and transport.
Opportunistic Meteorological Measurements
We need more observations of the atmosphere to support higher resolution models. One opportunity to retrieve these observations is to use existing sensors that are not intended for meteorological use, and turning them into something useful. Examples include sensors on autonomous vehicles (cameras, lidar, temperature and humidity, windscreen wiper speed), publicly available webcams or traffic cameras, street light sensors (for solar radiation) or even the attenuation between cellular towers (for precipitation). Home weather stations are an obvious example, but there are many challenges in the standardisation of sensors and representativity depending on the owner’s exact placement of the modules.
Machine Learning and Data Assimilation
Machine learning is an exciting new field which, when applied correctly, is very powerful. The previous categories above require high quality machine learning (e.g. using computer vision to recognise meteorological conditions or clouds, in cameras) to succeed. Data assimilation uses similar mathematical techniques to some machine learning methods, and is the key link between meteorological observations and forecasting, which we must get right if new observations are to have any value. Atmospheric radar is a good example of an untapped source of numerical weather prediction initialisation data; it is extremely difficult to give radar data fundamental physical meaning, and other potential observations such as camera images of clouds are the same. This field must be given equal consideration when developing techniques to utilise novel observations.
Other interests include hydrometeor type observations, flood forecasting, martian meteorology to enable human settlements, renewable energy forecasting, air quality forecasting, forecast communication.
