From the NASA - GPM / CoCoRaHS webinar back in February:
"All the rain gauges in the world would fit on 2 basketball courts"
(excluding CoCoRaHS)
if I did the math right, that's 84600 four inch gauges world-wide.
CoCoRaHS this morning listed 45588 station records, or ONE + BASKETBALL COURT(s) of CoCoRaHSian gauges.
That means all the rain gauges in the world fit on 3 basketball courts, and CoCoRaHs has a third of them!"
(sadly, only 20-25% make consistent reports).
Of the 45000+ about 19000 are considered 'active', with about 50% reporting consistently).
And I wonder if the NASA guys have any idea how many of us are on this forum, and if they're counting all us 'station' operators that aren't also CoCoRaHS????
