250k maps of ionospheric characteristics generated by [IRI-2020](https://irimodel.org/) spanning random dates 1958-2024 and random SSN 0-200 (not the true SSN for that date), with the goal of training a diffusion inpainting model to extrapolate plausible ionospheres. |
|
|
|
|
|
All maps are 1°x1° gridded, 361x181 with 180°W at the left, 180°E at the right, 90°N at the top, 90°S at the left. IRI settings are `JF(4:6)`, `JF(21:23)`, `JF(28:30)`, `JF(33:36)`, `JF(39:40)`, `JF(47)` false, all other JF true. |
|
|
|
|
|
Each file contains in PNG metadata `Datetime`: the date/time passed to IRI, as an ISO8601 string, and `Ssn`, the RZ(12) passed to IRI. |
|
|
|
|
|
`foe` is FoE, scaled to 0 = 0.5 MHz, 255 = 5 MHz. |
|
|
`fof2` is foF2, scaled to 0 = 1.5 MHz, 255 = 15 MHz. |
|
|
`hmf2` is hmF2, scaled to 0 = 150 km, 255 = 450 km. |
|
|
`mufd` is MUF(3000km), scaled to 0 = 5 MHz, 255 = 45 MHz. |
|
|
|
|
|
`combined` is an fof2 map in rows 0-180, a mufd map in rows 182-362, and an hmf2 map in rows 364-544. The intervening rows are cyan. |
