Correction involves adjusting older temperatures upward or downward (and more often downward) relative to current temperature enough to eliminate the breakpoint. Sometimes breakpoints are caused by changes in the time of day min-max thermometers are read and sometimes by station moves or changes in the station's surroundings. Problems that develop slowly and are corrected all at once represent a return to normal observing conditions and their correction biases the record. BEST creates two separate records at a breakpoint, thereby retaining any bias that develops slowly.

Ice Bath.<br />Kids these days are allowed to make psuedo-scientific weathercasts based on bad data and bad 'model-analysis' and scrutinize climate and coin phrases like climate crisis and 'superstorm this or that', when simple fundamental understanding of measurements and calibrations are lost. It's only basic science folks. Initialization is imperative to a sound forecast.Anonymoushttps://www.blogger.com/profile/04459190124574668943noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-47446197048047408682014-04-14T09:10:24.536-07:002014-04-14T09:10:24.536-07:00This is a stupid question (like: "..is the ap...This is a stupid question (like: "..is the appliance plugged to outlet?..."), but is there a chance that the sensors located at airports where large jet aircraft move around get "cooked" or "dirtied" by jet engine exhaust?

The simplest is cross checking with other instruments. Outliers need to be tossed, or at least investigated. And in any event unexplained outliers should generally not be used in averages and determining trends.RLLhttps://www.blogger.com/profile/13850927095383579725noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-40575955239226819862014-04-13T07:24:26.469-07:002014-04-13T07:24:26.469-07:00It surprises me that there are not redundant senso...It surprises me that there are not redundant sensors installed at a critical observation point like this.
