Summary of symbols for the primary variables in physical units and their interpretations

Symbol	Interpretation
t ∗	Time
x ∗,y ∗	Down- and cross-stream positions, respectively
$x_{\mathit{\text{source}}}^{\ast }$	Upwind position of source
Q ∗	Emission rate of detectable puffs
$\overline{U^{\ast }}$	Constant component of wind speed
K ∗	Eddy diffusivity
σ ∗ 2	Plume width parameter
$U_{\mathit{\text{gust}}}^{\ast }$	Magnitude parameter for gusts
$r_{\mathit{\text{gust}}}^{\ast }$	Mean rate of changes in gust direction
V ∗	Moth flight speed
${\rho }_{\mathit{\text{puff}}}^{\ast }$	Mean number of puffs detected per transit
$r_{\mathit{\text{puff}}}^{\ast }$	Detection radius for puffs
$r_{\mathit{\text{source}}}^{\ast }$	Detection radius for source

Symbols used in only one section of the analysis are defined in that section and omitted from this table.
