From subarcsec-seeing infrared images and spectra in the K and H bands, we present reflectivities and limb-darkening results for two of the hazy regions generated during the SL-9 collision. These highly reflective impact areas at methane infrared wavelengths have been studied in terms of multiple scattering radiative models. The results for both the H and D/G impact remnants show that a considerable amount of particles have been injected in jovian stratospheric levels from $\sim$1 mbar to the upper level of the assumed jovian tropospheric NH$_3$ ice haze ($\sim$300 mbar). Our models suggest a concentration of small particles, with mean radius of 0.15 $\mu$m for a real refractive index of 1.7. The imaginary refractive indices are in the range 1$\times$10$^{-4}$ to 1$\times$10$^{-3}$. For the H impact region, absorption at 2.0 $\mu$m is enhanced compared to unperturbed regions at the same scattering geometry. This enhancement is not observed in the older D/G complex.
