I'm not discussing the merits of the Folland canvas -
wooden bucket adjustment pre-1941, but the schedule of the implementation of the engine inlet adjustment.
Not exact matches
Yet a presumed change - over from
wooden to uninsulated canvas
buckets was the basis for the
adjustment that reduced the late 19th century cooling trend.
Note the significant warming
adjustment in the earlier half of the record that «corrects» for a change - over from
wooden buckets that were never known to have been used for temperature sampling in the first place.
A combined physical - empirical method (Folland and Parker, 1995) is used, as in the SAR, to estimate
adjustments to ships SST data obtained up to 1941 to compensate for heat losses from uninsulated (mainly canvas) or partly - insulated (mainly
wooden)
buckets (see Box 2.2).
As a result, Folland et al introduced an abrupt
adjustment of 0.3 deg C to all SST measurements prior to 1941 (with the amount of the
adjustment attenuated in the 19th century because of a hypothesized use of
wooden rather than canvas
buckets.)
The «scientific» circus of surface temperature measurement based on cool canvas
buckets, hot
wooden outhouses, ice - covered balloons and endless ad hoc «
adjustments» is ripe for a Feynman - type send - up.
