Analysis / Upper-Air / Europe

Upper-left: temperature in deg C
Lower-left: dewpoint in deg C
Upper-right: abbreviated geopotential height (this is the last three digits of the height value). If below 500 hPa, value is in meters, otherwise it is in dam.
Wind barb: wind speed in knots and wind direction

Black solid lines: geopotential height each 6 dam analyzed with Barnes algorithm from upper-air observations and first guess model data
Filled color contours with dashed lines: temperature each 4 deg C analyzed with Barnes algorithm from upper-air observations and first guess model data

Decoding time stamp example:

240416/1400

240416/1400: year=2024; month=04 (April); day=16; 1200=12:00 UTC
