Climate paper to: "Malcolm Hughes" , Tim Osborn , Briffa Keith Malcolm/Tim/Keith, As I go over the comments of the reviewers on our manuscript, I realize that one thing we clearly have to establish is the degree of potential overlap between the data used by MBH98 and the Briffa et al MXD network. At some level the data are clearly different--the gridding and standardization method applied to the MXD data underlying the Briffa et al network, if nothing else, is completely distinct from anything used by MBH98. On the other hand, MBH98 did use a certain number of density series. SEe the attached MBH98 data list (I believe the ITRDB data with an "x" in the title are density data). Can we clarify which data may be in common between the two datasets? Thanks in advance for the help, Mike ______________________________________________________________ Professor Michael E.
