Record Label : number_concentration_of_pm2p5_aerosol_particles_in_air
Record Title : Number Concentration of Pm2P5 Aerosol Particles in Air
CF Standard Name : number_concentration_of_pm2p5_aerosol_particles_in_air
Record Description : "Number concentration" means the number of particles or other specified objects per unit volume. "Pm2p5 aerosol" means atmospheric particulate compounds with an aerodynamic diameter of less than or equal to 2.5 micrometers. To specify the relative humidity and temperature at which the particle size applies, provide scalar coordinate variables with the standard names of, respectively, "relative_humidity" and "air_temperature".
Canonical Units : m-3
