BRAMS: Belgian RAdio Meteor Stations

BRAMS Data Tools

What is the BRAMS data Viewer ?

The BRAMS data viewer is an online tool developed by Yves Geunes (BIRA-IASB) which allows BRAMS users to access data archived at BIRA-IASB. The user can visualize the spectrograms and download the related WAV files. By default the spectrograms are centered on the frequency of the beacon and show a frequency range of 200 Hz. Please have a look at how to use the BRAMS data Viewer below before using it for the first time.

What is the BRAMS data availability tool ?

This is an online tool developed by Antoine Calegaro (BIRA-IASB) which allows BRAMS users to check about the availability of BRAMS data during a selected period and for selected BRAMS stations. The interface is similar to that of the BRAMS viewer. Please have a look at how to use the BRAMS data availability tool below before using it for the first time.

What is the BRAMS Downloader?

This is an online tool developed by Antoine Calegaro (BIRA-IASB) which allows BRAMS users to download a set of PNG images/spectrograms or a set of WAV files during a selected period and for selected BRAMS stations. The interface is similar to that of the BRAMS viewer. Please have a look at how to use the BRAMS downloader below before using it for the first time.

How to use the BRAMS data Viewer ?

  1. On top of the page are listed all BRAMS stations with existing data in the archive. Click on one or several stations for which you want to access the data.
  2. Select the date and time you want to get spectrograms for.
  3. Click on the "submit" button.
  4. Selected data appear below with the files available for that specific hour/date (e.g. 2001-03-31 04:00). The spectrograms at a given time are presented vertically if you selected several stations. They appear horizontally for consecutive spectrograms for a given station.

If you click on one spectrogram, a larger version appears as well as a number of buttons in the bottom middle part of the screen :

  • the "" button allows the user to loop through other spectrograms from the same station (but always within the hour you have initially selected).
  • the "" button allows the user to loop through other spectrograms from the same station (but always within the hour you have initially selected).
  • the "WAV" button allows the user to save the corresponding WAV file.
  • the "PNG" button allows the user to save the spectrogram itself (PNG format).
  • the "" button allows the user to loop through spectrograms of other stations at a given time (but only for those stations you have initially selected).
  • the "" button allows the user to loop through spectrograms of other stations at a given time (but only for those stations you have initially selected).

How to use the BRAMS data availability tool ?

  1. Select the time period where you want to check the availability of the BRAMS data
  2. Select the BRAMS stations
  3. Click on the "submit" button
  4. Results appear as colored bars. The color code is explained below

The color code for the bars uses 5 different colors according to the percentage of data available:

  1. green: 100% available
  2. light blue: 67% < availability < 100%
  3. yellow: 34% < availability <= 67%
  4. pink: 0% < availability <= 34%
  5. red : no data available

If you select only one day of data (e.g. from 2015-01-01 to 2015-01-02) the bars show you the availability of data using a simpler color code : red for no data and green for available data.

How to use the BRAMS downloader tool ?

  1. Check the station(s) you want to download files from
  2. Select the data type (WAV or Spectrograms)
  3. Select the time period
  4. Click on the "submit" button and wait for the transfer to complete

The downloaded files are placed in a ZIP archive organized by station code.
Please note that if you chose to download WAV files, data files will be grouped by hour in a TAR archive.
