Particle size is a notion introduced for comparing dimensions of solid particles (flecks), liquid particles (droplets), or gaseous particles (bubbles). The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size).

Correlation coefficient (also referred to as ρhv or rho) provides a measure of the consistency of the shapes and sizes of targets within the radar beam. A higher value shows a higher consistency in the size and shape of radar targets, while a lower value indicates greater variability in shapes and sizes.

Specific Differential Phase (KDP) is a derived product that shows the gradient, or change, in Differential Phase Shift (ΦDP). Positive KDP values indicate greater phase shift in the horizontal than the vertical.
Increasing KDP is an indication of an increase in the size and concentration of rain drops, and thus, an increase in rain rate. This means that KDP is useful for pinpointing areas where the heaviest rainfall is occurring.

Radial velocity of scatterers, away from instrument

# data[].attributes.definition
A velocity is a vector quantity. "Radial velocity away from instrument" means the component of the velocity along the line of sight of the instrument where positive implies movement away from the instrument (i.e. outward). The "instrument" (examples are radar and lidar) is the device used to make the observation. The "scatterers" are what causes the transmitted signal to be returned to the instrument (examples are aerosols, hydrometeors and refractive index irregularities), of whatever kind the instrument detects. A standard name referring to radial velocity "toward_instrument" should be used for a data variable having the opposite sign convention.

Groundwater recharge or deep drainage or deep percolation is a hydrologic process where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and or reclaimed water is routed to the subsurface.

dBZ stands for decibel relative to Z. It is a logarithmic dimensionless technical unit used in radar, mostly in weather radar, to compare the equivalent reflectivity factor (Z) of a radar signal reflected off a remote object (in mm6 per m3) to the return of a droplet of rain with a diameter of 1 mm (1 mm6 per m3). It is proportional to the number of drops per unit volume and the sixth power of drops' diameter and is thus used to estimate the rain or snow intensity.

Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll, found in cyanobacteria (also called blue-green algae). Because all phycobiliproteins are water-soluble, they cannot exist within the phospholipid cell membranes like carotenoids can. Instead, phycobiliproteins aggregate to form clusters that adhere to the membrane, called phycobilisomes.

# data[].attributes.definition
Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in cyanobacteria, red algae and cryptophytes,accessory to the main chlorophyll pigments responsible for photosynthesis.The red pigment is due to the prosthetic group, phycoerythrobilin, which gives phycoerythrin its red color.
