Single Particle Soot Photometer (SP2)

Project:

HIPPO2

Summary

The Single Particle Soot Photometer (SP2) is an instrument that directly measures the refractory black carbon (rBC) content in individual accumulation-mode aerosol particles and can identify iron-oxide-like aerosol composition and concentration (here refered to as light absorbing metallic (LAM) aerosol). This dataset contains SP2 rBC and LAM data measured aboard the NSF/NCAR GV during HIPPO-2. The data are in NASA AMES format.

Data Quality	final
Versions	1.0 (2012-12-07) 2.0 (2020-07-28): A reanalysis of HIPPO Single Particle Soot Photometer data was carried out to generate a new data product: the mass and number concentration of iron-oxide-like aerosols (here generally referred to as light absorbing metallic (LAM) particles), and the fraction of these that have detection properties consistent with anthropogenic iron oxides. The update adds these products to the files. The format of the files has been updated to reflect this, and file names harmonized between HIPPO campaigns. (Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
