Caution should be taken when accepting any extreme values reported from after 31/12/2021, as they will be from the non-quality controlled SYNOP dataset, whilst extremes from before 31/12/2021 have a much higher
likelihood of being correct (although still not 100%, if it is a site for which SYNOP records have been appended). Also note that the climatological day for which temperature records are valid is 09Z-09Z, values from MIDAS will adhere to this, values from SYNOP will do where possible, but may be approximated by a 12 hour extreme value.
Finally, there are some older records which have not been digitised and are thus not even present in MIDAS. To be absolutely certain, I recommend you check figures given here with NCIC and the Met Office.
Ticking the "Remove" box will constrain the map to only show sites which have an observational record up to the latest possible day, month or year.
This will eliminate both stations which are now closed, and manual climate stations which do not report a SYNOP but are present in MIDAS. It will also eliminate stations where an up-to-date SYNOP has not yet been received (typically a 99xxx site if in/near real time). Daily records should automatically update each day, as relevant observations are received.
Ticking the "broke record on latest ob" box will cause the map to only show stations which set their daily extreme record on the most recent ob.
Clicking on an individual site/temperature icon will open a pop-up, displaying site details including the record-span and year in which the extreme was recorded.
