How do weather services get sky conditions above the surface?

Maybe, but tests tend to stress me a lot and I don't do well on them.
I hate competition.

Competition?

You truly are a moron.

Buttman is the perfect instructor for you.

It's easy enough to establish measurement stations on the surface to measure

meteorologists to measure these things aloft? *Do they depend on PIREPs, or
expendable/recoverable probes and balloons, or satellites, or what?

Theres a little "eye" that looks up at the sky at various points. It
detects if there is cloud, or sky. The sensor is prone to errors,
though. Sometimes if it's broken, it'll say its overcast because some
of the sensors are pointing diagonally and are sensing the side of the
cloud. I had an ATC college-style text book that had a very
informative diagram of how they worked, but that book is long gone.


here is an example of one.

No imaging device there, just a couple of bolimeters.

I'm glad for your amusement, but do you think your amusement is worth the
dismantling of one of the (previously) most useful forums on aviation, by
aviators?

If you think that it is worth it, then you have too high of a value placed
on your own entertainment.

I took a 12 month vacation from RAP. He still didn't leave. When I came back
most of the posts I saw were MX, followed by bertie, followed by Max,
followed by bertie - max - bertie - max - - - - -

I'm trying to figure out how to set up my own nntp server, with my own
rules. Once I've got it up and running the way I want, I'll publish the
address.

Here's a preview:

You'll never see a post by MX, Bertie, or Max, nor will you ever see a
response to them.
You'll also never see a post by a spammer, unless a known poster decides to
spam, or if I decide it's not really spam.

You should really check out the AOPA forums; they are excellent. You
have to be a member to use them, but it is only 40 bucks a year and
WELL worth it.

That makes sense. I wonder how they estimate things like heights
and
distances, though. I suppose experience would help to come up with
educated guesses for these, but one might still be way off.
Certainly
experience would be useful in recognizing specific cloud types and
patterns.

One article I read (I think it was Wikipedia) mentioned just ten
radiosondes for the entire Caribbean, that's hardly what I'd call
high-resolution measurement. You could almost fit a hurricane
between
radiosondes.


You are an idiot.

Bertie

Maybe they use dopplar radar to tell the height of the clouds, eh?
Otherwise I assume some sort of math involving triangulation and other
difficult things.



Nah, it's easy. They compare the temperature to the dewpoint add in th
edry adiabatic lapse rate and voila, you get the cloudbase. Observation
is used for terminal areas, otherwise, though, it's still done the old
fashioned way for the most part. These days, al info is mixed together,
whihc gives a much better actual and forecasting capability.

Snort.

This is interesting. Is the OP in question saying that they have the
skills to fly a plane but *lack* the skills to configure a kilfile?
If so, this is indeed troubling news and would provide a clue as to
*why*
our skys are so unsafe today.


You're joking, of course, but in fact, you've hit the nail right on the
head.
Don't know about the OP, but a startling number of pilots today are
spoon fed idiots who need a Nintendo DS in front of them to do the
simplest flights...
