Here in the San Francisco Bay Area we've had coastal clouds in the
mornings with ceilings in the 1000-2000 range recently, 10-20 miles
west of Oakland the clouds dissipate completely. I was wondering
weather there exists a reliable way of determining the cloud tops
(other than PIREPs).

TIA


A little research yielded this information:

In addition, pilots are a vital source of upper-air weather
observations. In fact, aircraft in flight are the only means of
directly observing turbulence, icing, and height of cloud tops. For
more information on PIREPs, see Section 3. Recently some US and other
international airlines have equipped their aircraft with instruments
that automatically send weather observations via a satellite downlink.
These are important observations which are used by NCEP in their
production of forecasts. 1999

Well, perhaps inquiring of the person who was responsible for TWEB,
and asking him which products now contain the cloud top data might be
fruitful: Judson Ladd, W/SR1x2, Regional Aviation Meteorologist,
(817) 978-2652 Ext. 109.

I listened to a TWEB earlier today, so they are not discontinued. (ENM).
