Is there any equipment that us home weather broadcasters can get hold of
that can determin cloud height, I have read that it is usaully determined by
infrared from the ground. Or is there another way we can do it, besides
just guessing?

thnx

Found it some place on the net:

CLOUD HEIGHT

The cloud height on this site is an estimate of cumulus clouds using a formula based on temperature and dew point. Actual measurements of cloud height are made with a Micropulse Lidar (MPL). This device fires a laser into the sky and measures the backscattered signal. Costs for such a device are beyond the scope of weather hobbyists.
You can use the following formulas to calculate the height (H) of a cumulus cloud base given surface temperature and dewpoint.

A) H(meters)=125*(Tc-Tdc)

B) H(feet)=222(Tf-Tdf)

Note:
A) Tc and Tdc in formula are temperature and dewpoint in degrees Celsius.
B) Tf and Tdf in formula are temperature and dewpoint in degrees Fahrenheit.

Dickie,

Of course their is equipment available, just depends on how much we are willing to spend on our hobby :>

Check this out, doesn't have a price, but if you have to ask I guess you can't afford it, isn't that the saying?

http://www.allweatherinc.com/meteorological/8339_ceilometer.html

Or if you don't want to spend any money here is another method:

http://asd-www.larc.nasa.gov/SCOOL/lesson_plans/altlab.html

Now there is also ballons, they can be fun ! Need to know how fast they rise and you can do the calculations, but you could also put them on a long string marked with measurement intervals.

Actually everything I have read is that for us hobby folks is to estimate based on the type of clouds and use the Metar reports from a location close to us.

• Thnx Steve, I saw the first one when i was looking today, I figured since the price isnt listed, it means we cant afford it...lol Dickie ... From:

Message 6 of 6 , Jan 27, 2007

I have been looking for something like this for almost a year.  Is there anything that will work as well for stratus, cirrus or some of the other cloud types?

Thanks for this one though
