sorry,this is wrong.
always wind measurements takes & report (metar,synoptic etc) 10m above the ground ;)

We want to see "İstanbul New Airport" on Airport Metar section.
İt's call LTFM with ICAO code

in picture shows LTFA 1250Z METAR at 19:00 UTC, and tagged as 1h ago !!
(see picture)

the cause of the bug;
***LTFA's last METAR made at end of day (at sunset)
***LTFA ( C Type meteorology service , day VFR)
***LTBL ( A Type meteorology service , 7/24 )

info;
***3 km between the two airports
***info boxes takes at same time,

for your info,sincerely

Hmm, I found this MADIS site.but I have no idea what it says :)

Notes 5 - MADIS Surface Variables
"Wind speed and direction are reported and stored in the database. The user can optionally select u & v wind components and those will be calculated and returned. The QC results from speed and direction will be used In either case, and if one of the map projections has been selected via the MSETDOM call, the winds will be rotated to match the projection. The documentation in the COOP cdl was changed to remove the height of the anemometer. All anemometers are at 10 meters heights except for (GYX, TANM3, and STYN6) which are at 3 meters."

**ok.problem is moving operation between LTBA and LTFM.
**When the work is finished ;LTFM use IST IATA code (LTBA is still using this)
**LTFM METAR&TAFs distributing from met servise to all.
** this situation explained with latest NOTAMs for ourairports.com team

what do u mean "meteo info" for LTFM ?
How can i add meteo ?

@Gkikas-LGPZ
