Two detected example in which the mass determination methodology did not work. Left: the filled red square denotes the particle q_s and υ_s at altitude z_s. The black data points represent the q versus υ values of all CABMOD profiles at z_s. For the particle mass range that CABMOD uses (<2774 μg), CABMOD predicts that a particle with an entry angle, υ_s and q_s matching the particle should have completely ablated at z_s (i.e. not producing any ionization such that q=0 e⁻ m⁻¹). The insert boxes are a zomm in of the portion of the figure around the red dots. The periodic pattern in the modeled results is due to the resolution in υ, m and α of CABMOD.
