Downloadable Datasets

Datasets for Download

The Tracking Network provides downloadable data in two formats. You can query and view data for each Tracking Network content area in maps, tables, and charts through the Data Explorer and you can download datasets for the content areas listed on this page. Unlike Data Explorer data, the datasets presented here for download have not been aggregated spatially or temporally.

Data included below is subject to be changed, updated or reviewed at any time. Additional information is included in the metadata files available for download through the links below.

Drought

  • Each of these datasets provide data at the county level. The first three datasets include monthly index data from 1895-2016. The U.S. Drought Monitor dataset features weekly drought monitor values (ranging from 0-4) from 2000-2016.

Solar Radiation

  • Solar radiation datasets are available at the county level. Population-weighted Global Horizontal Irradiance (GHI) data are available by day from 1991-2012. Ozone Monitoring Instrument (OMI) Population-Weighted Ultraviolet (UV) irradiance data are available daily from 2004-2015.

Air Pollution

  • These datasets provide modeled predictions of particulate matter (PM2.5) and ozone levels from the Downscaler model. Data are at the census tract and county levels for 2001-2014. Census tract-level datasets contain estimates of the mean predicted concentration and associated standard error. County-level datasets include the maximum, median, mean, and population-weighted mean concentration.
