Bob and Markus,

 

Thanks, this seems consistent with the shape of the = late-night/early-morning amplitude characteristic in the LWPC simulation = (for 43N, 75W to Todmorden) that Paul sent to the group on March 1, = 2014: a smooth, fast transition (and particularly with minimal multimode = peak/null effects).

 

It’s interesting to note this characteristic (for this month, = frequency and path), but more interesting to note consistency of = Paul’s LWPC result with last-night’s = data.

 

I don’t think that the difference in paths from Bob’s = location to Todmorden and to Markus’ location should make much = difference in the shape of the late-night/early-morning amplitude = characteristic, but I could be wrong.

 

In another example of rough agreement between VLF models and test = results in this group’s efforts (for roughly similar paths and = times of year): the shape and magnitude of the phase characteristic = measured by Paul (for 43N, 75W to Todmorden) overnight March = 1st/2nd was consistent with a published model = (Chilton 1964, based on empirical data) for a path of roughly similar = land distance and water distance. The diurnal phase characteristic for = paths of this length and orientation (43N, 75W to Todmorden) varies = considerably month by month, so it was most interesting to see the close = correspondence  between Paul’s March = 1st/2nd measurements and Chilton’s 1964 = results for a different but analogous transatlantic path in early = March.
