The record high United States temperature would fail MADIS’s range test, although it would pass MesoW- est’s test. Both MADIS and MesoWest further employ a suite of tests that go beyond their simple range tests. “Bud- dy” tests compare an observation to neighboring observa- tions. MADIS uses Optimal Interpolation in conjunction with cross-validation to measure the conformity of an ob- servation to its neighbors [2]. MesoWest estimates observa- tions using multivariate linear regression [5]. A real obser- vation is compared to the estimate, and if the deviation is high, then the real observation is flagged as questionable. These approaches are flawed in that they do not account for bad metadata, such as incorrect timestamps or incorrect locations. They do not account for chronically bad sites which produce bad data including data that may sometimes appear correct. Of even greater concern, they may not do a good job in assessing accuracy and may be incorrectly la- beling bad data as good and good data as bad. The consequences of ignoring data quality are great. How can we trust our applications and models if the inputs are bad? In turn, how can we better assess data for quality so that we can be confident in its use? In this paper, we present new evaluation results for our previously-published method including evaluation with several new data sets. These results are significant in that they demonstrate the challenges of evaluation of methods for data quality assessment of spatio-temporal weather sen- sor data. The rest of this paper is organized as follows: Sec- tion II presents relevant literature, Section III identifies general challenges, Section IV defines our approach, I've always thought that the gladestone quality checking isn't really correct/ done the best in some occasions. For example, my nearest is usually the station at Grabreski , which temps etc can vary fairly drastically at times versus mine. Link to comment Share on other sites More sharing options...

If the Abnormal Extreme has become expected, isnt its absence noteworthy? Im certainly talking about it thus far! 65F this morning in Westchester.
