I can't get that to work, keeps asking me to enter the dewpoint temp
and units (which is a radio button with one enabled anyway). Isn't
it
supposed to be working out the dewpoint given the pressure,
temperature, wet bulb and RH?

.... As the question earlier in the thread was how to work out the *wet
bulb*, given the dry bulb and dew point, then this is the appropriate
link. However, for other requirements, you need to choose from this
list ....

for practical meteorologists like what I am, this is the 'wrong' way
round of course, because we usually start with the dry bulb and wet
bulb, then require the other parameters which is probably what you
were expecting.
