nucleus: In meteorology, a minute solid particle suspended in the atmosphere. Classification of nuclei is now generally made into "Aitken nuclei" of radius less than 0-2 [microns] "large nuclei" (radius from 0-2 to 1 [micron]) and "giant nuclei" (radius greater than 1 micron).

OBS

The term "nucleus" is slightly more specific that "particle"; but both are correct.

CONT

Les noyaux de condensation sont de dimensions variables : la plupart des noyaux d'Aitken sont très petits (inférieurs à 0,1 [micromètre]); il y a, par ailleurs, les gros noyaux, compris entre 0,1 et 1 [micromètre], et les noyaux géants, supérieurs à 1 [micromètre].

OBS

Le terme "particule" est moins spécifique que "noyau" ce qui revêt une certaine importance dans un domaine où les dimensions relatives des particules sont nombreuses.
