This may suggest that for a given optical thickness, the influence of particle shape on the radiative forcing caused by a cloud composed
of small ice crystals can be negligible.
The reduced variability in the retrieved De and Vf was attributed to the lower concentrations of
small ice crystals in the retrieved PSD.
With each heat shock,
small ice crystals melt, small air bubbles consolidate, and water and air molecules migrate through the serum.
To date, the airborne in situ measurements of the cirrus PSD have contained large uncertainties due to errors in
measuring small ice crystals (D ≲ 60 μm).
Mishchenko, M.I., and K. Sassen, 1998: Depolarization of lidar returns
by small ice crystals: An application to contrails.
By understanding the underlying physics producing the emissivity difference between these channels, this emissivity difference can be used to infer the relative concentration
of small ice crystals.
The faster you freeze your ice cream,
the smaller the ice crystals, as the water has less time to be driven out of the sugar - water solution to form ice crystals.
Repeat this stirring process two or three times, or until the granita has an even consistency of
small ice crystals; it should be grainy but not mushy.
Small ice crystals are formed which evaporate as the pressure is dropped and low levels of heat are applied.
The PSDs from the measurement - based PSD schemes are compared with corresponding retrieved PSDs to evaluate differences in
small ice crystal concentrations.
This paper presents a method to remotely estimate the concentration of
the small ice crystals relative to the larger ones using the 11 - and 12 - μm channels aboard several satellites.
