Click on coloured dot on map below for related soundings. Hover cursor over dot for name and RAOB number.
Those in red normally report midnight and midday UTC. Others (yellow) are occasional although Larkhill (Blue) (for the Salisbury Plain gunnery) often sends up a balloon at 0600. Click here to load all red stations in one go.
Warning - Check date displayed to ensure currency - some stations only produce data intermittently.
Note: midnight sounding might be labelled 2300 the previous day
Once chart appears and you have
checked the date and time position cursor
on bottom line at expected temperature eg T:26 (79F) 1016 mb and then click
or right click and enter Td (Dewpoint Temp), T (expected ground temp) and P

The red hatched area width gives an indication of thermal strength. The wider it is the stronger the expected thermals.
