Machine Learning Emulation of Urban Land Surface Processes
David Meyer, Sue Grimmond, Peter Dueben +2
Can we improve the modeling of urban land surface processes with machine learning (ML)? A prior comparison of urban land surface models (ULSMs) found that no single model is 'best'…
Machine Learning Emulation of 3D Cloud Radiative Effects
David Meyer, Robin J. Hogan, Peter D. Dueben +1
The treatment of cloud structure in numerical weather and climate models is often greatly simplified to make them computationally affordable. Here we propose to correct the Europea…
Copula-based synthetic data augmentation for machine-learning emulators
David Meyer, Thomas Nagler, Robin J. Hogan
Can we improve machine-learning (ML) emulators with synthetic data? If data are scarce or expensive to source and a physical model is available, statistically generated data may be…
Rainfall nowcasting by combining radars, microwave links and rain gauges
Blandine Bianchi, Peter Jan van Leeuwen, Robin J. Hogan +1
The objective of this work is to provide high-resolution rain rate maps at short lead-time forecasts (nowcasts) necessary to anticipate flooding and properly manage sewage systems…
Doppler lidar measurements of oriented planar ice crystals falling from supercooled and glaciated layer clouds
C. D. Westbrook, A. J. Illingworth, E. J. O'Connor +1
The properties of planar ice crystals settling horizontally have been investigated using a vertically-pointing Doppler lidar. Strong specular reflections were observed from their o…
The capacitance of pristine ice crystals and aggregate snowflakes
C. D. Westbrook, R. J. Hogan, A. J. Illingworth
A new method of accurately calculating the capacitance of realistic ice particles is described: such values are key to accurate estimates of deposition and evaporation rates in NWP…
Theory and observations of ice particle evolution in cirrus using Doppler radar: evidence for aggregation
C. D. Westbrook, R. J. Hogan, A. J. Illingworth +1
Vertically pointing Doppler radar has been used to study the evolution of ice particles as they sediment through a cirrus cloud. The measured Doppler fall speeds, together with rad…
