About sea-level pressure and QNH
Sea-level pressure is kept as given: the model’s own, or the figure entered from a forecast or report. QNH is that pressure the way an altimeter setting means it, through the standard atmosphere, and is what the adjusted apogee and the adjusted CSV use.

The log
Other makes of altimeter keep their settings on the device and do not write them into the log, so there are none to show here. This is what the file itself told us.

Same app and same export as the Mini. Use "Download Data (.csv)" on the flight page.
Files
Where the altimeter signs its log, the file carries that signature and a tick beside it. A tick means the data is unchanged since the device wrote it, which is what a record claim needs.
CSV
2971.csv
The log as columns of text. Opens in a spreadsheet, and in every simulator that reads flight data.

The weather for 48 hours either side of the launch, within 15 km of the launch site: NOAA GFS every hour, at the surface and up to about 31 km, and the NOAA GEFS ensemble where this site holds it. JSON, gzip compressed. Weather data by Open-Meteo.com (CC BY 4.0) and NOAA. For 2026-09-22 12:00 local time at 47.7059, -122.1385.

Adjusted CSV2904 recalculated in your browser
The log recomputed for your own sea-level pressure and temperature. Columns: time, altitude as recorded and adjusted, raw altitude as recorded and adjusted, pressure.
This file is built here from the signed log, so it carries no signature of its own. Anyone verifying a claim should be sent to the flight page and build their own from the original.
Share this flight
Anyone with the link can view this flight; nothing else on your account is shared.
Chart snapshot
A PNG of the chart exactly as you have it set right now: the series you have switched on, your zoom, your labels and any pressure correction applied.
Hotlink images
Stored images of the whole flight, altitude only, not your current chart view. Transparent, regenerated whenever the flight changes, and safe to hotlink on a forum.
