A little food for thought

As we all know, the "temperature of a day" at a location is determined by taking the high temperature for the day and adding to it the low, then dividing by two.

But what defines a "location?"

New Orleans has two airports. Only data from one determines the temperature of New Orleans, according to NOAA. At any given point in time, it is not unusual for them to be reporting temperatures that are 2, 3, 4 or more degrees different. Cloud cover, rain storms, and frontal movements are among the factors that play into variations of measurements between the two airports. Also, those temperatures are whole numbers, rounded off.

This is just a small example of the ambiguous data NOAA gathers. To use this data to say the earth has warmed or cooled hundredths of a degree is absurd.

1. And then we have morons comparing today's temps to those recorded back in 1880...

...as if the thermometers used back then were as accurate as the ones being used today.

2. The ones today are supposed to be accurate to within plus or minus 1 degree

That's not very accurate

7. laugh if you like

but the us navy has been collecting oceanographic data, including sea surface temperature, since 1838.

9. of course not

but increased accuracy, and precision of thermometers has been, to some extent, been driven by our defense needs.

17. Global warmers have fixed the accuracy of ocean temperature measurements

They decided the older measurements were too high. It made their current data look bad, so they "adjusted" the older measurements to reflect ocean warming.

20. the accuracy of ocean temperature measurements is determined by the military requirement

to find, identify, track and destroy man made objects under water.

anything else is incidental.

22. i linked to many of the data bases yesterday.

when capt wilkes (see "trent affair") began ocean temperature measurements (in 1838) i'm sure the interest was finding and measuring ocean currents. wilkes was still an active officer when the first submarines were launched.

13. it converged to the integral over space and time of the individual measurements

same as today.

with more data points, todays estimate is undoubtably closer.

10. Satellite Data

Satellite Data


The National Oceanic and Atmospheric Administration (NOAA) manages a
constellation of geostationary and polar-orbiting meteorological spacecrafts.
These satellites are distributed among three operational programs: the
Joint Polar Satellite System (JPSS), the Geostationary Operational Environmental
Satellite Program (GOES), and the Polar Operational Environmental Satellite
Program (POES). The U.S. Department of Defense operates the satellites of the
Defense Meteorological Satellite Program (DMSP) and NCEI archives and
distributes the data under the Shared Processing Program.

Geostationary and polar-orbiting satellites provide raw radiance data that are
collected by ground stations and archived by NCEI. These continuous global
environmental observations are then derived to produce various geophysical
variables that help to describe the Earth's atmospheric, oceanic, and terrestrial domains.

Geostationary satellites help monitor and predict weather and environmental
events including tropical systems, tornadoes, flash floods, dust storms, volcanic
eruptions, and forest fires. Polar-orbiting satellites collect data for weather, climate,
and environmental monitoring applications including precipitation, sea surface
temperatures, atmospheric temperature and humidity, sea ice extent, forest fires,
volcanic eruptions, global vegetation analysis, as well as search and rescue.
NOAA's satellite data improve the Nation's resilience to climate variability, maintain
our economic vitality, and improve the security and well-being of the public.

You do realize the data is still measured by mostly volunteers at ground based stations, right?

18. You've been whining about that since I got here.

What have you done about it beside try to convince people on the Internet that you know more about the methodology and it's accuracy than the people that can actually put things into orbit to study it?

Complain complain complain.
Get info from blogs that misrepresent or lie about data.. all been proven many times before.
Oh well, everyone needs something I guess...
