Is there any Web site where you can find the daily mean temperatures for major weather stations that use the 24 hourly readings—or maybe even more than 24 readings for a day? In this day and age, with all our computers, averaging the daily high and low just seems ludicrously primitive.
For instance, where I live, if you just averaged the high and low yesterday, the average temperature would have been 58. But if you used the hourly readings, the average was 55.7—a pretty big difference.
Anyway, surely there's some place online where we can find more accurate data for daily mean temperatures.
If anyone can offer any further info, I would greatly appreciate it.
