Let's do the time warp....

Let's do the time warp....
Excuse me while I use this balloon launch to also launch into reminiscence.

The Met. Office staff treated me as a VIP visitor and gave me a great personal tour of the office, new equipment and the station itself (visiting areas that tourists don't normally reach).

This balloon launch shows how technology has moved ahead in the 37 years since my term on the island. The inset note shows how it was done in the "old days", with a giant radar reflector. No need for that now, the radiosonde contains a GPS which sends back the height and position. Intstead of two people frantically calculating results for temperatures and wind, that is now done with a computer. So the sequence becomes launch, then return indoors for a coffee. The other change I really noted was the far greater emphasis on safety - we didn't think about protective gear!

Many thanks, Michael. The Weather Bureau provided the balloons. The one in the inset was a special high altitude type weighing 1200gm. The old radiosondes sent back only temperatures and pressures, so the balloon had to be tracked with a radar - now they also have a GPS sending the position and height: so a computer can then compute all the data.
