CRU data - Mann's code

[bo-no]

calibrate_correctmxd.pro

; We have previously (calibrate_mxd.pro) calibrated the high-pass
filtered
; MXD over 1911-1990, applied the calibration to unfiltered MXD data
(which
; gives a zero mean over 1881-1960) after extending the calibration to
boxes
; without temperature data (pl_calibmxd1.pro). We have identified and
; artificially removed (i.e. corrected) the decline in this calibrated
; data set. We now recalibrate this corrected calibrated dataset
against
; the unfiltered 1911-1990 temperature data, and apply the same
calibration
; to the corrected and uncorrected calibrated MXD data.

pl_decline.pro

; Now apply I completely artificial adjustment for the decline
; (only where coefficient is positive!)

Artificially removing or "adjusting" an inconvenient "decline" in a
data set is scientific fraud.
