Hi Climate Auditors
Since you appear to be coming in here, Eli and the anonymice would be happy to exchange comments with you. We appear to have intermittent and strange problems posting over there and frankly life is too short, and the weather too fine to try and fix the broken Audit filter. And so to bed.
UPDATE: TAC asks me to post some comments here on what Steve posted. Since it is late, Eli will simply point to the de Bilt site which discusses the adjustments and has links to papers that discuss the adjustments. I am sure Steve will now read them. This particular page was not linked by Steve nor Hans Erren directly.
Technical descriptionCorrections have been made for:
Please note the following:
- relocation combined with a transition of large open hut to a wooden Stevenson screen (September 1950).
- relocation of the Stevenson screen (August 1951).
- lowering of Stevenson screen from 2.2 m to 1.5 m (June 1961).
- transition of artificial ventilated Stevenson screen to the current KNMI round-plated screen (June 1993).
- warming trend of 0.11°C per century caused by urban warming.
- the transition of the wooden Stevenson to a PVC Stevenson screen (August 1980) did not have a noticeable effect on the daily mean temperatures; consequently no corrections had to be applied.
- from 1951 onwards, KNMI shifted from so-called climatological temperature measurements to synoptical measurements. However, the climatological measurements continued to 1970. For the 1951-1970 period these measurements may be considered as more reliable than the synoptical measurements. Therefore, in the homogenized series the climatological measurements extend to 1970.
- the present version of the series may change as soon as new results come available from the efforts of KNMI to homogenize the temperature series of De Bilt on a daily base, taking into account weather-dependent corrections.
