Experiment: Simulation Quiet
This simulation experiment was built to check the quality of the models during a non-disturbed ionosphere period.
The following models have been already evaluated:
A summarized comparison between them is shown in the Model Comparison section.
Configurations
Day of the year: 73 of 2015.
Simulated 3D grid: 2° x 2° x 20 km in latitude, longitude and altitude. Altitude coverage ranges from 50 to 20000 km.
A unique day was used to create the simulation experiment. Each hour of the day is composed by a 3D grid, where the grid cells were filled in with expected electron density values. A total of 24 maps were created to represent the whole day, so that we have a time resolution of one hour.
Input Data
Anyone interested to test a model can download the following Slant Total Electron Content (STEC) data. The STEC measurements were obtained by the simulated 3D grid based on the geometry of a global GNSS network. Around 2700 GNSS stations were used to generate the STEC data. Each file contains the XYZ coordinates of the GNSS receivers and satellites.
Validation Data
The validation is made in terms of VTEC maps, Ne maps, FoF2 maps, HmF2 maps and Ne profiles. After running the model, output files should be created exactly equals to the input files bellow, however with new columns, corresponding to the obtained Ne, TEC, FoF2 or hmF2 by the user model. Results shared with DIME will be included online (if approved by the user). See the table bellow to download the data to validate.
More details in the guideline.
IPP Coverage of the GNSS signals
The figure bellow shows the IPP (Ionospheric Pierce Point) coverage of the simulated STEC measurements obtained by the GNSS signals. GNSS signals were constructed based on a worldwide network of stations. We are using the same stations of the Storm 2015 experiment.
