Alpha and Charlie satellite residuals The magnetic residual between satellites Alpha and Charlie in the NEC-frame have been added as parameters. The residuals can be accessed together with magnetic data from Swarm Alpha.
Orbit number The orbit number has been added as a parameter counting the number of Equator crossings of the ascending node since the Swarm mission start.
Spacecraft as product parameter A new parameter "Spacecraft" has been introduced to downloaded data to easily identify which satellite downloaded data originates from within a product.
Several parameters to determine the position of the sun have been added as filters:
SunDeclination, SunRightAscension and SunHourAngle defining Sun position in the Equatorial Coordinate System
SunZenithAngle, SunAzimuthAngle defining Sun position in the local Horizontal Coordinate System
All new parameters described above can be downloaded as part of a product by selecting them with the "Custom download parameters" in the Download panel.
Cursor coordinates on globeOn hover of the globe in the Globe View, latitude and longitude for that point will be displayed in the top-left corner.
Extended Download panel functionalityParameter filters can be added directly in the Download panel by selecting "Add filter" in the Download panel. A Timestep filter enabling subsampling of the product. Subsampling can be enabled by selecting "Custom time subsampling" and specifying subsample interval in the Download panel. Subsampling will be applied to each daily product independently.
Product names in LayersSeveral data selections have been renamed:
"Electric Field Data" changed to "Equatorial electric field (EEF)"
"Electron data" changed to "Total electron content (TEC)"
"Currents data" changed to "Electric current data (FAC)"
"Non S/C" changed to "AC" (currently only includes combined S/C FAC data)
Model differenceThe difference between two models at any coefficient range can be displayed on the globe. This functionality can be accessed under settings of any of the geomagnetic models available in the Layers panel.
CHAOS-6Geomagnetic field model CHAOS-5 has been replaced by CHAOS-6 in the Layers panel.
Cartographic layer update"Blue Marble" layer previously available in the Layers panel has been updated with a "S2 Cloudless" mosaic, which has higher resolution and is based on Sentinel-2 data.
Release of Service v2.0 (20.03.2017)
Asynchronous processingIt is now possible to download filtered Swarm data from an arbitrarily large time span to one file. This can be done by defining your filters in the analytics view (in addition to area selection on the globe view) for a smaller time span. Once satisfied with your selection you can click on download. In the Download Manager which then appears you can set the time window of interest, then click on "Process & create link". The processing is then done in the background, the progress can be seen in the download panel. Once finished a download link is provided there for you to get the results. Download limit will be set to the equivalent of 50 Magnetic low rate products.
Ionospheric total electron content dataThe data from TECxTMS_2F has been added to VirES with the possibility to view the Absolute slant TEC, Relative slant TEC and the root mean square error of relative slant TEC on the globe. A new visualization was created for this product to display the TEC parameter value for each of the paths to nearby GPS satellites simultaneously. The values for a timestamp are shown one above the other, allowing one to quickly see how many satellites were visible and what the values were for each timestamp shown.
Field aligned current The data from FACxTMS_2F (single S/C soluton) and FAC_TMS_2F (combined S/C solution) has been added to VirES with the possibility to view the Field-aligned current (FAC) and Ionospheric radial current (IRC) on the globe and in the Analytics View. The combined S/C solution data can be found by selecting "Non S/C" and "Currents data (FAC)" in the Layers widget.
Dayside equatorial electric fieldThe data from EEFxTMS_2F has been added to VirES with the possibility to view the Estimate of the equatorial electric field (EEF) on the globe and in the Analytics View.
Local evaluation of custom modelProviding a more detailed rendering, one can restrict the evaluation of a custom uploaded spherical harmonics model to an area of interest with the Area Selection tool.
Updated backplane mapThe new version of the backplane map offers the following improvements:
Digital Elevation Model (DEM) data merged from SRTM, ASTER and regional/local data like EU-DEM
New shaded relief with better generalization and geotopographical features
Improved generalization of coastlines and land polygons
Updated OpenStreetMaps data
Removed data gap within Antarctica
Release of Service v1.2 (21.12.2016)
Resume sessionUpon 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 dateTo 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 filterIn 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 scalesWhen 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)
Plasma productsThe 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 productThe 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 changesThe 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 fieldsWhen 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 visualizationNow 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 modelsWhen 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 interactionWhen 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 removedThe 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 listThe 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-axisWhen 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 unitsThe units are now displayed in a parenthesis next to the axis parameter labels in the scatterplot.
Extended time selectionThe 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.
