How does Weatherlink deal with this?

The reason I ask is that my VP2 console say's since midnight I have had 10.4mm, yet WL downloaded back to my computer only say's 9.2mm. And adding up the individual entries it does add up to 9.2mm.

The first rainfall recorded was 03:30, yet looking at my old WMII, which is never changed from gmt, it rained between 00:45 and 02:00 in the morning. My suspicion is that it has fallen through the net, so to speak, in fact my WMII had a total of 11.2mm and normally they record very close as they sit next to each other.

Not the end of the world, but somethings adrift here I thinks.

For big data also
eg pompey at

There seems to be an offset in the surge predictor, if you look back
into the
archives , not observable on a day to day basis because of
meteorlogogical variability. Part of the year gives good agreement, on
averag, and then the other part of the year an offset bias observable in
the quasi-random pair plots.
GMT/BST vertical offset of about 0.15m problem, the transition step
seems to drift in a week or two after GMT-BST and then a week or two
after BST-GMT change. Perhaps due to the asymetric nature of tide plots
it gradually feeds through to a full step shift.

The only explanation I've got from anyone at the NOC is that the people
who set up the surge predictor, no longer work at the NOC , and there is
no one around to correct the code/data feed or whatever.
If it aint actually broke, don't fix it.
