Paleo Data Search

NCEI offers search and download of Paleoclimatic proxy data and Paleoclimate Reconstructions from the NOAA/World Data Service for Paleoclimatology archives. Over 10,000 data sets are available, derived from natural sources such as tree rings, ice cores, corals, and ocean and lake sediments. Use the General search box or Advanced search to improve filtering by investigators, locations, keywords and time periods. Data files for the entire result set, or a subset of it, can be bundled and downloaded as a single compressed file. A web service is also provided that you can use to get Paleo studies' metadata in JSON format. See the API help page for details.

The text search field supports Oracle Text parameters, such as 'AND', 'OR', and wildcards '%' and '_'.

When using general search, simply choose one or more Data Publishers, and enter some text to search for. By default all Data Types are searched, but you can select one or more to limit your search to only studies of the selected types.

The text search field supports Oracle Text parameters, such as 'AND', 'OR', and wildcards '%' and '_'. Special characters, like hyphens (-), semicolons (;), and single quotes ('), can be searched literally by escaping them with a backslash (\), for example as '\-' for a hyphen. See the api documentation entry for searchText for more details.

Advanced search uses the fields from the general section, as well as several more detailed options. Note that, due to the granularity of metadata provided to us, many of these options are not available depending on which Data Providers are selected. Some options, such as tree species, are only available for certain Data Types. For all fields, if nothing is specified by the user then the field does not constrain the search. If values from more than one field are selected, the result is the intersection of those groups of values.

  • Investigators, Locations, Keywords, and Species: Click on one or more values from the options on the left to constrain the search. If more than one value is selected, choose AND or OR to find studies containing all of the values or any of them. Each shuttle contains a filter area where text can be entered to narrow the list of selectable values. This text does not affect search results.
  • Location Lat/Lon/Elevation: Values can be entered to constrain the search to a specific area, or the bounding box on the map can be manually resized. Latitudes should be within the range -90 to 90, and Longitudes from -180 to 180. Longitude values can cross the antimeridian, e.g. the range 170 to -170 is valid. Elevations can be positive or negative.
  • Time: Time can be searched in years CE or years BP. These are functionally equivalent when converted correctly, and are provided for convenience only. Time constraints can be applied in three ways:
    • Overlap Any: Matches studies where any part of the time coverage lies between the specified min and max
    • Entirely Overlapped By: Matches studies with time coverages that completely bound the specified min and max
    • Overlap Entirely: Matches studies with time coverages that are completely bounded by the specified min and max

Search parameters can be used to find data files in selected studies for bundling in two different ways:

  • File Match: Only data files which match your search parameters will be included, regardless of matches on other data files in the same study. This is the narrower search option.
  • Study Match: All data files will be included from each selected study where any data file matches your search parameters. This is the broader search option.

Keyword searches filter by broad categories, such as geochemistry or population abundance, and are the only option for data types for which controlled variables have not been established. Variables searches allow filtering by specific proxy indicators such as Mg/Ca or delta 18O, and have been implemented for most data types.

The NOAA/World Data Center Paleoclimatology data search includes a "Data Bundling" option, which when selected will create a compressed zip file of the data meeting your search criteria, with some exceptions. Data held by our partners NEOTOMA and PANGAEA, as well as external links to Software and Data Repositories, will not be included in the data bundle. To obtain these data it will still be necessary to follow the individual data links presented in search results. In addition, NOAA/WDC Paleoclimatology has chosen to exempt some data sets from the bundling process because they generate large numbers of files when the "by Study" option is selected. These data sets will also need to be downloaded by following the individual data links in the search results. The NOAA/WDC Paleoclimatology data sets exempted from bundling are Studies containing hundreds of individual locations, i.e. gridded drought data products, the borehole temperature database, CLIMAP18k, LDEO CaCO3 database, and the Global Charcoal database.

Test our new search by measured variable and send comments to paleo@noaa.gov. Some datasets contributed in 2018 will not be returned in the variables search while we continue to enhance our updating capabilities, but all other search functions remain fully operational. This search was developed through a partnership between NOAA, the University of Colorado, and the U.S. National Science Foundation.
