Met Office Hadley 1.6c. Anomaly -2.08c.Provisional to 6th.
Metcheck 1.23c. Anomaly -2.97c.
N-W 1.48c. Anomaly -2.73c.
Mount Sorrel 1.4c. Anomaly -2.8c.
My Mean 0.7c. Anomaly -5.1c.
Yep the CET as recorded in the estimated HADOBS dataset is shown as 1.6C (same as the current estimated value).
Again I am afraid to say I have it as 1.3C
My method is to take the the min and max from the online hourly datasets (for the 24hr period (09:00 to 08:00 the following day)) which are shown on the web. Is this correct?
So my cumulative difference so far this month is 1.6C below the ones shown by MO. A daily difference of 0.26C so far.
PS I have only started doing this calculation this month!. I do know that some fairly large adjustments at the end of the month do sometimes occur, but is this normal?
I also notice that the other inidicators of CET shown above by Art are much lower that the MO ones. My adjustments will bring them all into a similar range . Just seems odd to me that they cannot be accurate on a daily (hourly?) basis when the up to date data is always currently available. Does it mean it is calculated manually at a certain time?
Any way what do I know, as I am new to all this!
