wind force to significantly disturb the air boundary layer.
Outside ambient temps above 40f rarely account for significant wind chills, and are thus not calculated
Daniel Gabriel Fahrenheit (1686-1736): the German physicist who invented the alcohol thermometer in 1709, and the mercury thermometer in 1714. In 1724, he introduced the temperature scale that bears his name.
The freezing point of water is 32 degrees Fahrenheit (written "32 °F"), whereas the boiling point is defined as 212 degrees. - How the seemingly arbitrary zero point was determined, is still open to debate.
Used primarily in the US.
Celsius and Centigrade:
The Celsius scale, invented by Swedish Astronomer Anders Celsius (1701-1744), is also referred to as the Centigrade scale. Centigrade means "consisting of or divided into 100".
Celsius (Centigrade) takes it's zero reference as being the freezing point of water, whereas 100 deg C is set at the boiling point of water. This equates to a temperature span of 1 deg C & K, as being precisely 1 part in 273.15 parts the difference between absolute zero and 0 deg C - or the freezing point of water at 1 atmosphere pressure.
More conducive to the metric system, degrees Celsius is more widely adopted in European countries, Canada and in engineering.
Lord William Thomson Kelvin expanded on the earlier work of Celsius and introduced the Kelvin Scale in 1848. The Kelvin Scale measures the ultimate extremes of hot and cold. -
Degrees Kelvin is the often preferred scientific notation of measuring temperature. A temperature differential of one degree Kelvin is the same temperature differential as one degree Celsius . The only difference between Celsius and Kelvin being that Kelvin uses 0 degrees to define Absolute Zero, which is -273.15°C. (thus 273.15K = 0°C).
Degrees Kelvin is used almost strictly in engineering.
Rankine °R (or °Ra).
William John Macquorn Rankine (1820-1872) was a Scottish engineer, known for his Rankine temperature scale & putting forth a thermodynamic theory stating the Law of Conservation of Energy (1853).
As with the Kelvin scale (symbol: K), zero on the Rankine scale is absolute zero, but the Rankine degree is defined as equal to one degree Fahrenheit, rather than the one degree Celsius as used by the Kelvin scale. Thus a temperature of -459.67 °F is precisely equal to 0 °R.
Degrees Rankine is used primarily in engineering.
The Réaumur scale (°Ré) is a temperature scale named after René Antoine Ferchault de Réaumur, who first proposed it in 1731.
The freezing point of water is 0 degrees Réaumur, while the boiling point of water is defined as 80 degrees Réaumur. Exactly how René arrived at 80 as being the boiling point of water, is open to some conjecture. It's is hypothesized that it was chosen since the number 80 could be halved 4 times and still be an integer (40, 20, 10, 5 making scales easier to read). By contrast, the number 100, could only be halved twice and still remain an integer (50, 25). The other is that the volume of displacement for each degree in his thermometer was to represent 1/1,000th the volume of the bulb. Using that metric, water boiled at 80 °Ré. Whatever his logic, the scale is no longer used, except in the traditional making of some Italian Cheeses.

We're often asked: How exactly do we determine the cloud base ? (height of the lowest part of the cloud (cloud base) compensated for Mean Sea Level).
In days of old, cloud base was often determined by stereoscopic instruments that used simple range finding techniques often performed by a technician, or in other cases, reported via more direct means such as live pilot reports, known as Pireps... Though reasonably accurate during daytime hours with adequate light, night-time data was most accurately derived from pireps at most major airports. In other words: cloud base (especially in reduced visibility) was often determined when the approaching aircraft finally "broke out" of the slop on an ILS (Instrument Landing System) approach to reveal either the "Rabbit" (sequenced strobes leading the approaching aircraft on final, to the runway threshold) or the runway marker lights themselves. Later optical rangefinder based systems were partially automated, but accuracy left something to be desired and cloud base data was available normally only at the major airports or Govt weather sites.
Today, such cloud base measurements have been replaced with LIDAR (LIght Detection And Ranging) that emits a pulsed laser beam, and measures the time it takes for any reflection from the cloud base to be returned. Perhaps a bit over-simplified (ok... way over-simplified), but nothing more than an over glorified laser pointer/cat laser toy, but aimed vertically. Only real difference is that the laser is pulsed & the ceilometer microcode simply measures the time it takes for any reflection off the cloud base to be returned. Conceptually, the same as radar, but instead, uses light in the form of a pulsed laser, instead of microwaves. Since the speed of light in our atmosphere is known to a great deal of precision, the time it takes for any reflection from the cloud base to be reflected back & reach the sensor, equates to a highly accurate measurement. Cloud base measurements are now automatically determined, often accurate to within +/- 14 feet, & up to a height of 60,0000 feet and available 24/7. (the CL3 is only capable of up to 25,000 ft).... Since the base of many cloud types are not well defined, the software averages the past 20 samples to calculate the height of the lowest cloud layer. LIDAR technology makes accurate cloud/ceiling measurements, affordable even to the private /personal weather stations... The pulsed beam instead of being visible, operates at a wavelength of 910nm which is solidly into the the infrared - just outside the visible spectrum of from 380 to 750nm. The long wavelength, also is much better able to penetrate and negate the effects of haze. Thus there is no visible laser beam to draw attention or aggravate our neighbors ! (though much more powerful than a tv remote, it's visibly as innocuous as the laser "beam" emitted by your TV remote control )...
A visibility measuring device was also considered for this station, however the WebCam image would seem to more than suffice for practical purposes !
Groundhog Day - Candlemas
Perhaps in light of the CRU and the IPCC falsifying data to fit their political agendas, perhaps in some twisted way, Punxsutawney Phil on Groundhog Day may be a far better prognosticator of future weather conditions. At least he doesn't call sunny, overcast, or pouring down rain, sunny conditions... and its doubtful he has any knowledge of hockey stick graphs !
Anyways, It's no accident that Groundhog Day and Candlemas are celebrated together, for both are closely related... each signifying the triumph of light over darkness, spring over winter.
Candlemas was originally a Celtic festival
marking the midpoint of the season. Why Feb 2nd ??? Feb
2nd most years marks the Sun's declination as being halfway in its advance from
the winter solstice to the spring equinox. It was not without religious
ties as well... The Christian church expanded this festival of light to
commemorate the purification of the Virgin Mary and her presentation of the
infant Jesus in the Temple. Candlelit processions accompanied the feast day. A
central part of the festivities was the forecasting of either the arrival of an
early spring or a winter that would linger. Sunshine on Candlemas was said to
indicate the return of winter. Similarly, "When the wind’s in the east on
Candlemas Day , there it will stick till the second of May."
A bear was the "bearer" (pun brazenly intended) of the forecast to the people of France and England, while those in Germany adopted the badger as their prognosticator. In the 1800s, German immigrants to Pennsylvania brought with them their Candlemas legends. Problem was; seems there were no badgers in the area ! What to do ??? There were however lots of groundhogs. Ergo: the groundhog became the New World's recognized prognosticator of whether or not we would have an early or late spring.
Today that lore has grown into a full-blown festival in no other than Punxsutawney, Pennsylvania, with Punxsutawney Phil presiding for over the past 120 years as of 2010. For all things groundhog, visit the folks at Punxsutawney and see what Phil is predicting this year. Beware: on Feb 2, it might be difficult to establish a connection, as their servers get "pounded"... Also Wikipedia has some interesting information including Phil's historical predictions dating from 1887 to 2010. http://en.wikipedia.org/wiki/Groundhog_Day
Punxsutawney Phil isn't the only groundhog to make predictions....

Phil with his observations.
If Candlemas be fair and bright,
Winter has another flight.
If Candlemas brings clouds and rain,
Winter will not come again.
