Data Access

To download the waveforms in mseed format it's necessary to select networks through proper button, which open a selection menu with a toggle button for each network. It's possible to repeat the selection for the stations. User choices is reported in the text area below, and then add them to the download list. You can also add stations from the search tab, where you can check/uncheck the resulting stations and then add them to the download list. All the channels available for the stations are added to the list and it is possible to exclude unwanted ones. For the download operation it's necessary to select a time interval (UTC format). By clicking on start/end date and time fields it's possible open and close proper selectors. It is possible to download both a file for each station and a single file containing the data of all the stations. Downloading restricted data requires entering a specific authentication token.

To download station information it's necessary to select networks through proper button, which open a selection menu with a toggle button for each network. It's possible to repeat the selection for the stations. User choices is reported in the text area below. You can also add stations from the search tab, where you can check/uncheck the resulting stations and then add them to the download list, It is also possible to select the information level (network, station, channel, response) and the output format of the response. Optionally it's possible to select both a time filter (UTC) and spatial coordinates filter to narrow down the field of the request.

This tool allows checking stations data availability.

This tool allows checking data quality as mean, standard deviation, gaps and overlaps.

Select in sequence the network, the station and the channels, with a time interval (max 1h for seismogram, max 1d for helicorder), then click on specific button to view the proper seismograph.
