Validation of model-based correction for non-Stokesian tracers

In-situ flow-tracking measurements at scales on the order of 10 m3 and larger remain a challenge. The large size tracers required for optical visibility results in an inertial lag inherently low seeding density. For instance, natural snowfall, fake snow soap bubbles 2 cm have been used as field extracted statistical quantities (Nemes et al., 2017; Wei 2021; Rosi 2014). There is also growing interest networks sensors remote- measurement where access impossible (Bolt al. 2020; Villa 2016). Onboard units (IMU) are promising tool high-resolution over spatial domains without access. However, due to intrinsic lag, dynamic-model-based correction tracking transient phenomena, sketched figure 1. In present study, tracer-velocity evaluated by quantifying residual error measured flow velocity after method Galler (2021) applied.
