Single Particle Soot Photometer (SP2) BBOP
Abstract
The SP2 provides information on the amounts of rBC (refractory black carbon) and of other, non-refractory substances associated with individual rBC containing particles by simultaneously measuring the scattering and incandescence signals of such particles that are directed through the cavity of a 1064 nm Nd:YAG laser. rBC concentration is reported at STP conditions Time resolution: 10 sec Uncertainty: ~ 25% SP2 unit used: 24 Calibration: Fullerene soot with variable mobility density. No correction for OC content in Fullerene (recent study on SP2 sensitivity to differing black carbon types reports that non-refractory material content for fullerene soot is about 20%). SP2_dateTime: UTC Mass equivalent diameters (SP2_min; SP2_geo; and SP2_max) are in units of micrometers dN/dLogDp counts (SP2_cnts_0...SP2_cnts_199) are in units of #/cc" rBC mass concentration is in units of ng/m3. Note that the rBC column length is one field shorter than the SP2_datetime column. Last time field is not relevant to the rBC time series (see comment below on length of SP2_datetime column) Lengths for SP2_max; SP2_min; SP2_geo are one field longer then the number of SP2_cnts_XX columns . This is to provide bounds for image plots (if desired). Length for SP2_datetime is one field longer than that length of themore »
