Open It Up

So: 5% of the Earth's temperature is
determined by 50 (actually it's more like 30, but call it 50) thermometers
reporting daily. .05X = 50 so we have about 1,000 thermometers to determine
the Earth's land temperature. Since the land is 30% of the earth's surface,
.30X = 1000 and we have 3,333 thermometers to determine the entire
temperature of the earth. (I doubt we have that many, but it'll do for
this.) That means 3,333 data points ever hour, or 29,200,000 data points a
year. At 8 bytes per data point we're talking about 2 gigabytes of data per
year; meaning that everyone reading this has the capacity to store that much
data, and probably the computing power to do daily averages and print out
trend curves.
That's publishing a few
gigabytes of data per year, or some 10 megabytes a day. Let everyone on
earth look at the data, and do things like calculate differences between raw
and corrected data. We can all look at the trends and differences.
