    Dear Alicia,
         My review of this paper is attached. As you'll be able to gather I think that such
    an analysis is speculative, as volcanic events are infrequent so the sample count is
   small.
    I've made some suggestions that the authors should consider. It will be
    difficult to do what I suggest and make it convincing, but I think there
    needs to more and extracting the ENSO signal is one way to highlight what's
    left. It certainly helped with the paper in Nature in last week's issue.
    Best Regards
    Phil

     Hi Phil-
       Thanks for agreeing to help us with this manuscript.  I will send you a link to the
     manuscript and instructions for referees in an e-mail to follow shortly.
       I would be grateful if you could consider the following questions in your review.  Do
     you feel that this represents an advance in our understanding of the tropical response
     to volcanic forcing?  Tropical climate over the past 4 centuries more generally?  Does
     the record generated fully support the conclusions?
       Thanks again for your help.  I look forward to reading you comments!

     Alicia

      Alicia,
        OK. Send the manuscript or details of how to access it.
      Cheers

     Dear Professor Jones
     As you may have heard, we have recently launched Nature Geoscience, a monthly research
     journal (please see our website [2]http://www.nature.com/ngeo for more information).
     A short manuscript has been submitted to Nature Geoscience, which we were hoping you
     would be interested in reviewing. The manuscript comes from Rosanne D'Arrigo, Rob
     Wilson, and Alexander Tudhope and is entitled "Impact of volcanic forcing on tropical
     temperatures during the last four centuries". Its first paragraph is pasted below.
     Would you be able to assess the novelty and importance of this manuscript for us, within
     about 14 days of receiving the paper?
     If you are unable to help us with this, can you suggest any alternative referees who
     would have an appropriate expertise? I would also be grateful for any thoughts that you
     might have regarding other referees who would be appropriate to complement your
     expertise on this work.
     Thank you in advance for your help and I look forward to hearing from you soon.
     Yours sincerely

     Impact of volcanic forcing on tropical temperatures during the last four centuries
     Rosanne D'Arrigo, Rob Wilson, and Alexander Tudhope
     Knowledge of volcanism's impact on tropical climate is limited prior to the instrumental
     period, yet important for understanding climate variability. Here we combine 19 coral,
     tree-ring and ice core proxies into an annual composite record that provides a
     comprehensive view of volcanism's impact on tropical sea surface temperatures (SSTs)
     during recent centuries. We find an association between tropical volcanism and cold
     reconstructed tropical temperatures, although the cooling is spatially variable across
     the tropics. Only minimal cooling is observed following extratropical eruptions. Severe
     conditions following the (likely tropical) unknown1 and Tambora, Indonesia eruptions of
     the early 1800s suggest that this was the coldest sustained period of the Little Ice Age
     in the tropics. By contrast, the tropical impact of the 1600 Huaynaputina, Peru event2
     appears much weaker than at higher latitudes, but the number of tropical proxies at this
     time is low. Our
     results have implications for how the tropical ocean-atmosphere system responds to
     natural and anthropogenic radiative forcing.
