Notes: Cloud Condensation Nuclei concentrations are from the DMT CCN Counter (SN 076) operated at 0.6 supersaturation measured on the top of Clifford Hall in units of #/cm^3. The AERONET value is the Optical Depth at 500 nm for the UND AERONET station. Condensation Particle Concentration (CPC) are from a model TSI 3771 counter and measures all particles larger than 10 nm in units of #/cm^3. The SMPS values is the peak in the accumulation mode aerosol in units of nm. The TEOM values is the total mass of aerosol less than 2.5 um. Values are averages from 9-10 am local time.
