The Hive: University of Utah Research Data Repository. https://doi.org/10.7278/S5d-khd5-xqhg --------------------- DATA & FILE OVERVIEW --------------------- 1. File List A. Filename: NeVLFpropinclin5.dat Short description: Electron density profile collected from https://ccmc.gsfc.nasa.gov/models/IRI~2016/ for Jan 2020 at a resolution of 1km, then interpolated smoothly to a resolution of 0.1km with no abrupt jumps. B. Filename: NiVLFpropinclin5.dat Short description: O+ ion density profile taken from https://ccmc.gsfc.nasa.gov/models/IRI~2016/ for Jan 2020 at a resolution of 1km, then interpolated smoothly to a resolution of 0.1km with no abrupt jumps. C. Filename: NiHplusVLFpropinclin5HighlatAmerica.dat Short description: H+ ion density profile collected from https://ccmc.gsfc.nasa.gov/models/IRI~2016/ for Jan 2020 at a resolution of 1km, then interpolated smoothly to a resolution of 0.1km with no abrupt jumps. 2. Relationship between files: They are independent files using the same dataset (linked above) for Jan 2020. 3. Additional related data collected that was not included in the current data package: NA 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: https://ccmc.gsfc.nasa.gov/models/IRI~2016/ - the data here is generated analytically and experimentally. The major data sources are the worldwide network of ionosondes, the powerful incoherent scatter radars (Jicamarca, Arecibo, Millstone Hill, Malvern, St. Santin), the ISIS and Alouette topside sounders, and in situ instruments flown on many satellites and rockets. The IRI model and software is updated according to the decisions of the IRI Working Group. The software package includes the FORTRAN subroutines, model coefficients (CCIR, URSI, IGRF), indices files (IG_RZ.DAT, APF107.DAT) and README and LICENSE files. The IRI build-up and formulas are described in detail in a 158-page NSSDC report by Bilitza (1990) and more recently in a 65-page Reviews of Geophysics paper by Bilitza et al. (2022) 2. Methods for processing the data: We directly download the final verison of the file from ccmc website. The only processing we do is interpolation to a higher resolution file so we cna use it for out 3D FDTD model. 3. Instrument- or software-specific information needed to interpret the data: None. Only Excel is needed, which is a widely available tool. 4. Standards and calibration information, if appropriate: NA 5. Environmental/experimental conditions: NA 6. Describe any quality-assurance procedures performed on the data: The data was loaded into excel for plotting, where checks to confirm no NAN were completed. 7. People involved with sample collection, processing, analysis and/or submission: NA --------------------------------------------------- DATA-SPECIFIC INFORMATION FOR: NeVLFpropinclin5.dat --------------------------------------------------- 1.
