Not much ppt is Shap - I think it still needs an observer to go and measure the snowfall on a daily basis.

Great list, thanks for that.

I also thought the precipitation for Shap must be wrong, presumably due to non-measurement of snow?

Re Shap - there was an entry for every day of the month, many were just "trace"

I will see if I can confirm, but the data did appear to have been quality controlled checked .

Paul - just realised that your WL mean temp' is calculated by integration.

thought you might have at least commented on my contribution to the letters page of COL re calculating mean temps.

I wonder which of integration or the standard calculation on WL would match your screen monthly means the best?

Darren - I did see your letter. To be honest I dont understand it ( or the reply you got ). I tend not to compare my mean temps that weatherlink produce in comparison with my screen data as there change over time is midnight. ? I may look at a yearly data set to see if there is any major differences but from month to month I stick to the screen data backed up by "Cumulus" as its runing 0900-0900hrs

basically it is how Wl can be set to calculate a monthly mean temp' - mine, as is yours, was set to calculate it by 'integration' ie: it uses all the days data (mine is set for every 5 mins - so add up the low+high temp in those 5 mins 288 times and divide by 288).

standard way we all know.

what i didn't know was that WL can be changed to the standard way - that is what the reply was about - i have now changed WL from integration to standard, but you can 'toggle' between the two.

You just then have to decide the merits of both - and in part that is what my letter was about.

integration is a more honest way and more precise
Standard is the way its always been done.
