@John Smith <[email protected]> glad that worked for you. Everyone: all of this led me to take a look at what the UK WOW wants <https://wow.metoffice.gov.uk/support/dataformats#pressure>. It's even more confusing. Rather than have a well-defined API, they let the user choose what "baromin" means.
Pressure & MSLP: Some weather stations record Mean Sea Level Pressure, and some record Station Pressure (also referred to as Air Pressure). The Site Definition in WOW will be used to determine which pressure measurement to use. If your site specifies a unit for Air Pressure, and MSLP is marked as 'Not Captured', then baromin will be treated as an Air Pressure reading. Otherwise it will be treated as an MSLP reading. To edit your site definition and ensure the correct pressure is selected, visit the edit pages of your site and the options for pressure will be near the bottom. Ensure one is set to 'hectopascals (hPa)' and the other is set to 'not captured'. WOW will then automatically work out the other measurement and store it for you. I don't know what they mean by "If your site specifies a unit for Air Pressure." In any case, we send "barometer", which is pressure corrected for altitude and temperature. Reading this very confusing passage, I think we should send "altimeter" and remind users to mark MSLP as "Captured." Any other opinions? -tk On Thu, Sep 25, 2025 at 4:14 AM Jimi Lawson <[email protected]> wrote: > @Ton vanN & @steepleian > I came to the same conclusion after an extensive internet search (I only > found 2 references to this, 1 on this thread and 1 on WOW-BE) and I also > contacted the UK MET Office and asked the following questions > > 1.
