date: Tue Nov 16 08:57:47 1999 from: Tim Osborn subject: time series for WMO diagram to: p.jones@uea The age-banded density Briffa et al. series can be got from: /cru/u2/f055/tree6/NHtemp_agebandbriffa.dat It is ready calibrated in deg C wrt. 1961-90, against the average Apr-Sep land temperature north of 20N. It goes from 1402 to 1994 - but you really ought to replace the values from 1961 onwards with observed temperatures due to the decline. Rather than give you a new file of your reconstruction (Jones et al.) that is re-calibrated, I thought it was easier to just give you the coefficients. Your original normalised file should be multiplied by 0.3856, and then subtract 0.1112 to give the calibrated time series, i.e.: CAL = (X*0.3856) - 0.1112 Cheers Tim
