Default Question - Melted Hoar Frost/Rime - is it counted in Rainfall Totals?

Thanks for your help Ken - I will note it in the Notes column of my Davis
database.

I did some Observing in the Met Office back in the 60's & 70's, but some of
the detail of entering the data has long gone from my memory!
I still have an old RAF Form 2050B Daily Register (January 1964). The hours
I spent checking the entries of the previous shift! Probably all shredded
by now!

A question ( I'm sure I used to know the answer!)

Should I count the 'rain' recorded by my tipping bucket by melted frost
in
my rain totals, or should I note it but delete from totals?
I have had one 'tip' for today and one yesterday (i.e. 0.2mm each)


Hi, Roy,
It should be added to your monthly total and a daily note made that it
was dew or hoar.
Met O practice is to enter XX and the amount,
thus 0.2mm dew/hoar etc would be entered XX02
If rain has fallen, but none in the gauge, enter trace, (Met O form X
in the left hand column)
There are lots of other rules that I will let you know if and when a
problem arises
