Please tell me you are not supposed to record this as a rain day if
you do record 0.2mm, otherwise I've been cocking up for 30 yrs!!

I do include it Ian, in Met O returns and all other statistical
outlets.

In the Met Office return, we are simply asked to total days with 0.2mm
or more.

However, after over 20 years of sending data to the Met O, Ken taught
me something I didn't know today about the double xx before the 0.2mm
for dew/frost - a trace x is fine, but the other passed me by all this
time.

Unfortunately, the new automated system of submitting climate
returns to the Met Office, known as OWL, is not able to
differentiate between 0.2mm from rain and 0.2mm from other
hydrometeors, so this useful distinction is now more-or-less at
an end.

In my own log book I still note such events as (0.2)w for dew,
(0.2)x for hoar or rime, (0.2)fe for wet fog (where the letter
after the bracket is a subscript), as I always have done.
