SPARTAN data types

Commonality

All products are presented as CSV files and reported by sites. At the beginning of each file, there is a data version and date of update. Basic site information (name, location, etc) is provided at the first few columns of the file, followed by the dates of the samples (see section 3.2.1 in this paper for description of our 9-day sampling method). The reported variables can be identified by either Parameter_Name or Parameter_Code. The last few columns provide information on the methodology and quality check. A comprehensive list of the methodologies is here.

The following sections give brief introductions and examples of each data type.

Additional information on the sites can be found on the Site Details Sheet.

PM2.5 & PM10 speciation

The PM2.5 & PM10 speciation product report the direct measurements of total mass and chemical composition including water soluble ions from IC, trace elements from XRF and ICPMS, carbons from SSR, HIPS, and FTIR. Relevant SOPs are reported on the official SPARTAN website.

Reconstructed Fine Mass

The reconstructed fine mass builds on the speciation data to provide estimation of ammoniated sulfate, ammonium nitrate, sea salt, fine soil (dust), equivalent BC/EC, trace element oxides, and residual matters (assumed to be organics). Based on the estimated composition, the k-Kohler constant can also be estiamted. More can be found in the RCFM SOP.
