I'm surprised by some of the blank areas on the chart he
http://www.metoffice.gov.uk/hadobs/ I checked a month or so back that
there are stations in those areas that are currently reporting which
were also reporting sixty years ago. I can only assume that there
hasn't been a continuous record but there are techniques for solving
that problem so why haven't they been used?
