Sentences with phrase «cool bias»

Moreover, they suggested that if there was any residual bias, it was probably a slight cooling bias!
This shift has resulted in a well documented increasing cool bias over the last several decades and is addressed by applying a correction to the data.
This shift has resulted in a well documented increasing cool bias over the last several decades and is addressed by applying a correction to the data.
A recent paper by Hausfather et al found that NOAA's new SST version ERRSTv4 matched sea surface temperatures from buoys (and satellites) quite well from 1997 until present, whereas HadSST3 had an apparent residual cooling bias in the same period.
«We found all three agree almost perfectly with the new NOAA record, [and] show a strong cooling bias in the old NOAA record,» Hausfather said.
The HadSST2 record included a «bucket correction» for data collected before 1942, to correct for a known cool bias in the data.
Both series show a weak warm bias around 1998 followed by a rapid transition to a strong cool bias driven by the missing data from both poles.
The existence of two distinct cool biases in different versions of the temperature record may of course have contributed to the fact that the problems went undetected.
In addition, some Argo floats have had pressure sensor issues which impose a further cooling bias.
IMHO, I believe both TMT and TLT are somewhat influenced by a cooling stratosphere (e. g. cooling bias).
Menne (2010) addressed this concern and found a slight cool bias in poorly - sited stations.
«We found all three agree almost perfectly with the new NOAA record, [and] show a strong cooling bias in the old NOAA record.»
These effects both contribute to an increasing cool bias in the HadCRUT3 data.
Given the considerable technical challenges involved in adjusting satellite - based estimates of TLT changes for inhomogeneities [Mears et al., 2006, 2011b], a residual cool bias in the observations can not be ruled out, and may also contribute to the offset between the model and observed average TLT trends.»
The study also suggests two other widely - used sea surface temperature datasets, the Hadley Centre's HadSST3 record and the Japanese COBE - SST record, have significant «cool biases» due to treating all measuring instruments equally.
The radiosonde record is markedly less spatially complete than the surface record and increasing evidence suggests that it is very likely that a number of records have a cooling bias, especially in the tropics.
Early estimates of ocean heat from the Argo showed a cooling bias due to pressure sensor issues.
However, there have been teething problems with the Argo buoys experiencing pressure sensor issues that impose a cooling bias on the data.
Recall that in 2015, NOAA corrected a cooling bias arising from the failure to account for the changing ship - buoy mix in the ERSST data set.
In essence, the paper, On the Reliability of the U.S. Surface Temperature Record (pdf), concludes that the instrument issues, as long acknowledged, are real, but the poor stations tend to have a slight cool bias, not a warm one.
We present scientific evidence that any effect which reduces the slope of the vertical temperature profile within a stably stratified surface boundary layer will introduce a warm bias, while any process that increases the magnitude of the slope of the vertical temperature profile in a stably stratified surface boundary layer will introduce a cool bias, remains a robust finding based on boundary layer dynamics.»
Nevertheless, contrarians continue that the lower atmosphere isn't warming as fast as it should be, or that the surface thermometer measurements are biased hot (recent research has shown they actually have a cool bias).
