• 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
