Station clock and troposphere monitoring

The real-time estimates of the stations clocks applies a filter to remove the linear model to better characterize each clock stability. Real-time estimates of Zenital Tropospheric Delay (ZTD) for each station are computed according (see "5.4.2 Tropospheric Delay")

The AATR and MSTID indexes: monitoring local and regional the ionosphere

The implementation of the Along Arc TEC Ratio (AATR) and Medium Scale Traveling Ionospheric Disturbances (MSTID) detector indexes is intended to serve as complementary tools to dynamically adapt the process noise variables implemented in the IONO4HAS model to the actual ionospheric activity. The daily-cumulative plots five stations are chosen randomly (in accordance with high, medium, low and ewuatorial latitudes) from the whole set of IONO4HAS working stations.

Worldwide plots represents areas in which is possible ot obtain the indexes, using the whole network of IONO4HAS working stations. The green-yellow-red colour code is used to denote a weak, medium or strong ionosphere activity. The 24-hour image animation of the two-layers ionospheric modelling is presented next for yesterday computed data.

Real-time ionospheric plots

Provided corrections and modelling of the ionosphere is given using a two layer model. The following animations are made up with images every 5 minutes (300 s), representing the first and second layer values and its corresponding sigma values.

Other non-related monitoring products: Solar Flare Detection

Solar Flares (SF) refer to sudden increase of electromagnetic radiation from the sun lasting from minutes to hours. The sudden increase of the energy emmitted by the sun produces an over-ionization of the earth's ionosphere that can be measured using the resulting delays on the radiomagnetic signals of a global network of GNSS dual-frequency receivers.
The following plots represent the real-time SF index during the current day, the set of stations implemented to compute the index, and the reference data to compare with: the NASA GOES X-ray measurmenent [Ref].
