Welcome to SPARTAN-Cloud’s documentation!

SPARTAN (Surface PARTiculate mAtter Network) measures and provides surface ambient particulate matter (PM_2.5 and PM₁₀) concentration around the world, started in 2012. Currently, there are 29 active sites (as of Dec 2023). Check out the SPARTAN website for our collaborators worldwide!

SPARTAN sites are intentionally colocated with AERONET Sunphotometers to provide the only global dataset that directly connects ground-based PM_2.5 and satellite remote sensing. In addition to filter-based PM_2.5 and PM₁₀ mass, SPARTAN also measures the chemical composition using IC, XRF, SSR, etc. Our SOPs provide the details of the measurements. Measured chemical compostion together with total mass are reported in our speciation products. We also reconstruct fine particulate matter into commonly studied chemical groups and repored by the reconstructed fine mass product. Aerosol scattering is also measured and reported as our Nephelometer product. When both PM_2.5 mass concentration and fine aerosol scattering data are available, time-resolved product at daily and hourly resolution are reported. More about our products on SPARTAN data type.

SPARTAN data have been used in studies on anthropogenic fugitive, combustion and industrial dust emission, global sources of fine particulate matter, global variation in airborne metal, sector and fuel type contributions to ambient PM:sub:`2.5 and attributable mortality <https://www.nature.com/articles/s41467-021-23853-y>`_, Mortality- Air Pollution Associations in Low Exposure Environments (MAPLE), a global-scale mineral dust equation, and elemental characterization of ambient PM. More to come in the following years!

SPARTAN-on-cloud project provides easy access to the latest SPARTAN data on the Amazon Web Services (AWS) cloud, supported by the AWS Open Data Sponsorship Program.

Note

SPARTAN is a grass-roots network run by individual scientists who share their measurements as a public good. We request that you consult our citation policy to credit developers when including SPARTAN data in your publications.
