Release of Service v1.2 (21.12.2016)

Features:

• Resume session
  Upon termination of your session information about the view, time window, area, data and filter selections and all corresponding settings will be stored for your convenience. Upon restart of the service, your session will be resumed where you left off. The session state information is stored locally with your internet browser, unless VirES is accessed using private browsing.
• Jump to date
  To quickly access data from any part of the Swarm mission, press on the button in the top right corner of the timeslider slider. This will allow you to display data from a date of your choice. The time selection will be on a corresponding time of day as your previous time selection. If the previous time selection passes over midnight, the selection will be clipped to end at midnight
• Set detailed download time filter
  In addition to filtering Swarm products by a wide range of parameters when downloading, you can select "Custom time selection" in the Download Manager. This will make it possible to define a precise start and end time for the downloaded product. Other filters shown in the Download Manager will still apply to the data
• New overlay layers
  Three new overlays are available from the layers panel:
  • Coastlines and Countries: Black coastlines with light grey country borders
  • Graticules: Grid lines for geographic longitude/latitude
  • Magnetic graticules: Grid lines for magnetic longitude/latitude
• Additional colour scales
  When selecting Swarm products or models to display on the globe, the colour representation of the data can be set in the respective settings widgets found in the Layers widget. It is now possible to choose between 27 scales including ones such as viridis, plasma and portland. The names of custom1 and custom2 colour scales have been changed to diverging_1 and diverging_2 to better represent the corresponding style.

Release of Service v1.1 (26.09.2016)

Features:

• Plasma products
  The data from EFIX_PL_1B have been added to VirES with the possibility to view the plasma density and temperature, in addition to the spacecraft velocity and potential both on the globe and in the Analytics View. The full set of parameters are accessible on download
• Ionospheric bubble product
  The data from IBI_TMS_2F have been added to VirES with the possibility to view the bubble probability on the globe and in the Analytics View. Positive Bubble index detections are shown in the time slider. The full set of parameters are accessible on download
• Layers interface changes
  The Layers widget has changed separating out satellite specific products. Selecting a satellite specific product is now independent of selecting what satellites to view data from. Selection of satellite is done using separate checkboxes in the Layers widget. This change was introduced to make the Layers widget more compact after adding more products.
• Customize download fields
  When downloading data, in addition to customizing the exact filter values and format, it is possible to specify what parameters to include by ticking off on "Custom download parameters", then either select the data from a dropdown menu or type it in. This customization allows for parameters from multiple Swarm products.
• Label with colorscale information directly integrated into globe visualization
  Now when using the save function the currently configured color scale and ranges are saved also into the image. It is possible to toggle the visualization of the label in the settings panel for each Layer using the "Legend" tickbox.
• Dynamic range calculation for models
  When changing model parameters (for SIFM, IGRF12, CHAOS-5 and Custom Model), such as the coefficient range or height, the colorscale range is calculated and adjusted automatically. It is still possible to manually adjust the range with both textfields available in the settings panel. This change was introduced as it became clear that finding the correct range after changing model parameters was cumbersome for users and we wanted to facilitate the process.
• Single axis interaction
  When exploring the scatterplot, one can scroll when hovering over an axis to zoom along one axis while keeping the other axes ranges fixed. Similarily one can drag on an axis to pan the plot. These features apply to both the x-axis and the y-axes and complement the zooming and panning one can perform on the scatterplot itself to zoom along all axes.
• Zoom limit removed
  The zoom limit previously applied to the scatterplot is now removed. There are now no restrictions to how far you can zoom in or out. A reset button is added to enable the user to return to the initial zoom level and position at one's convenience.
• Customizable filter list
  The data filter histograms found in the Analytics View can be removed individually, and new histograms for any other available parameter can be added by selecting it in the histogram "Add" dropdown menu. Any active filters will be removed when its corresponding histogram is removed. In addition the filters can be hidden to allow for more space for the scatterplot.
• Secondary y-axis
  When selecting multiple parameters a second y-axis will appear. When selecting two parameters this means that each parameter has its own axis. If more than two parameters are selected, they will be grouped according to their range, such that the parameters with the most similar value ranges are grouped together and share an axis.
• Scatterplot units
  The units are now displayed in a parenthesis next to the axis parameter labels in the scatterplot.
• Extended time selection
  The time selection limit when selecting a time window from the time slider has been extended from 15 days to 30 days. The limit when downloading products has not changed and is still set at the equivalent of 5 unfiltered MAGX_LR products.
