Thank you
Sorry, don’t want to start a new thread, though someone else certainly could...from one of the emails:
“We are using the combined dataste for the estimation as this
should produce better rbar values around coasts and islands. If we
used the land only dataset we would have real problems with
isolated islands and with some coasts ( where all neighbouring
boxes will be in one direction from the coastal box).
2) Having got fields of the monthly rbars we’ll then apply the
formula to the land-only dataset. As you’re doing something
similar with the marine dataset, we can remerge the two
variance corrected datasets using David’s merging ( growing
land and neighbour checking) program.
3) We will then write this up as a small paper for GRL, about
the land only results. Both of you can be on this if you want.
We can decide later what to do about the merged dataset.
4) applying the correction in real time in the future will mean
that we will always be slightly changing approximately the last
15 years data - because of the filter end effects. Best would
seem to be to maintain the present version we have and apply
this variance correction every few years ( eg the IPCC cycle !).

also, “variance problem” may be a good keyword
