CDAWeb Data Explorer

Select start and stop times from which to GET or PLOT data:

        Start time (YYYY/MM/DD HH:MM:SS.mmm):

        Stop time  (YYYY/MM/DD HH:MM:SS.mmm):

Compute uniformly spaced binned data for scalar/vector/spectrogram data (not available with noise filtering)

Use spike removal to filter data without binning (not available with noise filtering)(Warning: Experimental !!).

Select an activity:

Data Availability Chart : Generate a chart showing when data is available for the selected data set(s) and time range (Select > 1day).

List Data (ASCII/CSV): select one or more variables from list below and press submit. (Works best for < 31 days)

Output listing times as year and seconds of year (Default is dd-mm-yyyy hh:mm:ss)

CSV options.

Data and global attribute info in CSV.
Data in CSV, Header in JSON.
Data/Headers in JSON.

Download original files : press submit button to retrieve list of files. (Max. 200 days - use HTTPS site for larger requests)

Include Master CDF with download set.

Create V3.9 CDFs for download: select one or more variables from the list below and press submit.

Create Version 2.7.2 compatible CDFs (Default is Version 3.9)

Create audio files based on data from selected variables. More information about audification.

Note: CDF patch required for reading Version 3.9 CDFs in IDL or MATLAB.

Get CDFX - IDL GUI plotting/listing toolkit software. To be used with either the daily or "created" CDF files available above.

Pressing the "Submit" button will spawn a new window/tab in order to support the new "Previous" and "Next" functions.

Variable parameters (required for Listing, Creating and Plotting data only)
