Next message: George Huxtable: "The Online Nautical Almanac- beware!"
Thanks to Frank Reed for explaining further that when he wrote-
"By the way, since you're inland, be
advised that you should use "sea level" barometric pressure. This differs a
little from the pressure usually reported in weather reports (but not very much
unless you're at Denver-like altitudes)."
he intended that local true barometric pressure at the observer's altitude
should be used, not the pressure at sea-level. He could have fooled me (and
did). I had quite misunderstood his meaning. After the clarification, we
now seem to agree on that point.
George.
