I supposed balloons were used only for atmospheric sounding anymore.
I didn't know they were still used *anywhere* as a substitute for = ceilometers. I'm pretty sure I remember ceilometers being deployed 45 or more years = ago. "J Haggerty" wrote in message = news:Qk_Bd.4488$2_4.750@okepread06... Most weather ceilings are now determined by machine (a laser=20 ceilometer), even if it's relayed by a human. The old balloon method=20 that determined ceilings by how long it took for the balloon to enter=20 the clouds is only used these days at those sites that don't have a=20 working ceilometer. =20 JPH =20
