This page allows you to download data sets from one or more instruments. Simply select one or more instrument types (e.g. magnetometer) to display the available instruments / instrument arrays and their associated observatories. Select the observatory or observatories of interest and the required time span, and then initiate the download.

Your requested data packages are accessible under the Results links at the bottom of the page.

Please note the following:

1. All download policies or restrictions applicable will be applied to each data set requested. If any restriction or policy for any data set, or for the entire download, is not met, the download will not proceed.
2. At least 1 site (observatory) must be selected.
3. Individual data sets from each site - instrument combination will remain separate; however, these will be aggregated into a single file for your convenience in downloading. For example, if the zip format is selected for the download, a single zip file will be produced, containing one or more individual zip files for each site - instrument combination requested. The individual zip files will be named according to the standard format for the specified instrument.
4. Sites that contain multiple instruments will be listed only once, as multi-instrument sites. Selecting these sites will cause all data sets for the selected instruments that exist at the site for which data exists in the selected time span to be aggregated into the download file.
5. If multiple instruments and sites are selected, all available data will be returned. If no data is available for one or more of the selected combination(s) of instrument type, instrument, site and time span, no download file will be made available for that combination. That is, the system will make available all data matching the search, and will not notify you of any site - instrument combinations that did not have data available that matched your search criteria.
6. If only one site - instrument combination is selected and there is no data available in the given time span, no download file will be made available and you will be notified that no data matches your search criteria.
