Daily range of 21.4 degC up here at Whipsnade, from 9.1 to 30.5,
which for what is essentially a hilltop site is quite remarkable. I've been
surprised at how cool the nights here have been during both hot
spells since I moved in last month. At the moment the only
instrumentation is in the garden which is located in a shallow dell
some 15m or so below the crest of the escarpment. I suspect that
may be sufficient to produce some big differences under radiation
conditions between this site and the intended observatory site on
the crest.
