<name>eSWua IONOWORD tool: Nowcasting global TEC maps</name>
<description>
The TEC Global nowcasting is based on data from the GNSS station of the International GNSS Service (IGS) network ingested into NeQuick2 model. In particular, differences between measured and modelled TEC are computed at each IPP in order to create a global map representing the differences among actual and modelled TEC distribution. Such map is added to the map calculated by running NeQuick2 in order to obtain the TEC nowcasting. The algorithm provides TEC real-time maps with a spatial resolution of 2.5° X 2.5° (lat x long) on a global scale (latitudinal and longitudinal ranges of 87.5°S–87.5°N and 180°W–180°E, respectively) and a refresh time of 15 min.

<description>
In this page it's possible to plot specific TEC data (both hisotrical and near-real time). In particular it’s possible to plot the mean TEC/TEC deviation time-series, the hourly TEC mean and the Latitudinal/Longitudinal distribution of TEC. Multiple plots can be added to the page, allowing the comparison among different areas/time-periods.
