Here, we examine this emerging method in detail and delve deeper into the specifics of the modelling process for a single noctuid moth, with the hope of illuminating the importance of different aspects of the process by varying the morphometric and compositional properties of the model. This was accomplished by creating a high-fidelity three-dimensional insect model by micro-CT scanning a gold-palladium-coated insect. Electromagnetic simulations of the insect model were conducted by applying different morphological and compositional configurations using the WiPL-D Pro 3D Electromagnetic Solver. The simulation results show that high-resolution modelling of insects has advantages compared to the simple ellipsoidal models used in previous studies. We find that the inclusion of wings and separating the composition of the body, wings, and legs and antennae have an impact on ...

The case studies used in this study are from two campaigns: PICASSO (Parameterising Ice Clouds using Airborne obServationS and triple-frequency dOppler radar) project based in the south of England and CONCIRTO (CONvection, CIRrus and tropical Tropopause layer over the Indian Ocean) based at the Maido Observatory in La Reunion. Previous methods have relied on statistics to make up for observations that are not collocated, which gives rise to further uncertainties. This analysis showcases how geodesy can be implemented prior to observations and during post analysis to provide the best observations, improving collocation by a factor of 10.
