Size resolved denotes the capability of an instrument to measure aerosol properties in different size ranges. The size range of particles is typically given as a range of particle diameters in nm assuming spherical shape and must be provided in a comment attribute. Number concentration means the number of particles or other specified objects per unit volume. Cloud droplets are spherical and typically a few micrometers to a few tens of micrometers in diameter. An upper limit of 0.2 mm diameter is sometimes used to distinguish between cloud droplets and drizzle drops, but in active cumulus clouds strong updrafts can maintain much larger cloud droplets.
