cc: mas@noc.soton.ac.uk ,"Janice Darch" date: Mon Sep 8 12:27:57 2008 from: Keith Briffa subject: NERC/T/S/2002/0040 - extension request re. final report to: snbl@nerc.ac.uk To Sasha Leigh Natural Environment Research Council Polaris House North Star Avenue Swindon SN2 1EU Dear Sasha following our initial phone conversation this morning, I am now following up with a more formal request for an extension - see below. ------------------------------------------------------------------------------------------- ------------------------------------------------------------------ Please can we formally request a 2-month extension to the deadline for submission of the final report of our NERC (Rapid Climate Change) grant NER/T/S/2002/00440 "Quantitative applications of high-resolution late Holocene proxy data sets: estimating climate sensitivity and thermohaline circulation influences". The report submission deadline is 29th September 2008. We would like to request an extension of this deadline until the last day of November 2008. The reason/justification for this request is that it would allow us to complete another suite of energy balance model simulations that we are currently undertaking in order to better apply a maximum likelihood approach for constraining climate model parameters based on comparison with pseudo-proxy and actual temperature reconstructions. We undertook related model simulations during spring 2008 but have subsequently decided that the analysis will benefit from additional model simulations. Tim Osborn and myself are currently making these runs but we envisage another month or so after which time we will need to analyse the results. We are very anxious to incorporate at least preliminary findings of these runs in the final project report. It is for this reason that we are requesting a 2-month extension. ------------------------------------------------------------------------------------------- ------------------------------------------------------------------ I am also cc'ing this request to Dr. Meric Srokosz for information (I understand that he is prepared to sanction this request) and Dr. Janice Darch (our Research Administrator - who will forward it to the relevant parties in the UEA Research Office). with thanks Keith -- Professor Keith Briffa, Climatic Research Unit University of East Anglia Norwich, NR4 7TJ, U.K. Phone: +44-1603-593909 Fax: +44-1603-507784 [1]http://www.cru.uea.ac.uk/cru/people/briffa/
