   Dear Saburo Miyahara,
   I am willing to review this manuscript, but will be away on holiday for the next 3 weeks
   and thus wouldn't be able to return my review until mid-June or soon after.  If that's
   adequate then let me know and I'll click on "accept"; if it's not then please find another
   reviewer (Prof. Phil Jones, p.jones@uea.ac.uk, is suitable as he has done some v. closely
   related work, but he is away for the next 1 to 2 weeks too).
   Regards
   Tim

     Dear Dr. Osborn:
     Would you be willing and available to review "Are temperature-sensitive proxies adequate
     for North Atlantic Oscillation reconstructions?" by Eduardo Zorita, Eduardo Zorita,
     Fidel Gonzalez-Rouco, submitted for possible publication in the Geophysical Research
     Letters.
     The manuscript's abstract is:
         Recent reconstructions of the North Atlantic Oscillation
     Index(NAOI) for the last few centuries
     are mostly based on statistical models linking this
     index with proxy
     records. The underlying assumption is that the
     statistical relationship between the NAO and the
     indicators are
     stable in time and independent of time scale. This assumption
     might not be physically substantiated, since at  time scales of
     centuries,
     other processes, such as solar variability, might
     disturb the link
     between the NAOI and temperature-sensitive proxy indicators.
     The statistical approach for NAOI reconstructions was tested
     using a
     climate simulation with a state-of-the art climate model driven
     by
     external forcing of the last 490 years as a surrogate for the
     real climate.
     Two kinds of  indicators were tested, temperature-sensitive and
     precipitation sensitive. It was found that, in this surrogate
     climate, the
     NAOI reconstructions based on precipitation-sensitive proxies
     are  more reliable than the reconstructions based on
     temperature-sensitive proxies.
     If you agree to review this manuscript, I would ask for your comments within 14 days
     from your acceptance.
