HOW TO USE

Follow the 7 steps for a properly usage of DIME.

STEP 1: Choose the case of study of interest. Select based on the available datasets.

STEP 2: Download files from all instruments given in the Dataset table. In the Storm 2013 case, for instance, one should download the ten datasets given by altimeter data and other instruments.

STEP 3: Read the files and run the model of interest to the location and time indicated in the files. Each file was created in a very friendly way for reading. The estimated parameters by the model should be equal to the parameters indicated in the files. Depending on the instrument, the estimated parameters are the electron density (Ne), Vertical Electron Content (VTEC), critical frequency (foF2) and the peak height (hmF2).

STEP 4: After running the models, the user needs to create output files exactly equals to the input files, however with a new column, corresponding to the obtained Ne, TEC, FoF2 or hmF2 by the user model. In case of ionosondes, two columns need to be created, related to hmF2 and FoF2, respectively.

STEP 5: In case of locations or times in which no data was computed by the user model, please, include NaN as a value.

STEP 6: Once the output files are produced, send all files to fabricioprol@hotmail.com, subject: sharing results with DIME. Together with the e-mail, please, include all characteristics of the model. Use this example and this example as a basis.

STEP 7: All graphs will be generated and sent by email to the user. A request will be made to ask for a confirmation to share the model results in DIME.

WHO CAN USE

Anyone interested in the evaluation of ionospheric and plasmaspheric models in terms of electron density is welcomed to use DIME. A main restriction needs to be outlined for a fair comparison between the models.

RESTRICTION: Files from the dataset cannot be used as input to the model to be evaluated

Also, it is completely discouraged to evaluate models using Ne, FoF2, or HmF2 observations obtained at the days of interest.

Climatological models, such as the International Reference Ionosphere or NeQuick, are encouraged to be evaluated. Physics-based models, such as TIE-GCM or SUPIM, are also encouraged to be evaluated. Finally, tomographic algorithms or data assimilation schemes using GNSS data are encouraged to be evaluated.
