Station Information
Category: Baseline Station

In February 2004, a TSI 3010 CN counter was deployed at SMO. The TSI CN counter (and its associated components) is a significant upgrade from the Pollack counter instrument which was previously operated at SMO. The new instrument will provide continuous 1-min frequency measurement of CN concentrations at the station. Data acquisition is done using a laptop running Redhat Linux and is transmitted to ESRL daily.

SMO Aerosol Properties Plots

These plots are designed to provide a quick look at the measured aerosol properties. They display raw unedited data, but known corrections for instrument errors have been applied.
