TEC Time Series Plotter

Which locations on Earth do you want to analyse?

Simply add some locations to your time series plot by clicking the map or by entering the coordinates or address in the form below the map. You can remove locations by using a right click on the previously selected locations or delete all locations at once by just using the appropriate button below the map. Feel free to readjust the color of the selected grid cells, which will correspond to the color in the time series plot, by clicking multiple times on the same cell.

Which time period, time interval or GNSS frequency do you want to analyse?

Please specify the start and the end time of the time series according to your downloaded ESPAS data. You can also limit the data processing time by setting a time interval of interest. Select a GNSS frequency, if you are interested in the corresponding range error instead of TEC.

You already downloaded SWACI TEC maps from ESPAS?

Fine, then you only need to specify the location of your downloaded ESPAS data and click the progress bar to start generating the time series plot, otherwise please visit the ESPAS data portal first and download some SWACI TEC maps.

The data is plotted right after the import of your ESPAS data was successful. Feel free to readjust your filter settings to refresh your time series plot. You can pan and zoom the time series and also temporary deactivate several graphs by clicking the legend without reprocessing.

After processing you may download the data in JSON format or as PNG file for further investigations by using the menu on the right top of the plot.
