RSS a trend of 0.078 C / decade.
RSS: 0.52 So, in conclusion, warming since — oh wait,
our RSS trend is from 1994 to now.
We find that GISS disagrees with both RSS and UAH satellite trends on 17 - year spans (and they disagree with each other), but that there is symmetry: GISS agrees broadly more with UAH trend (though not amplitude) for the 17 years ending 1997, but more with
RSS trend in the last 17 years (though again not with amplitude).
The RSS trend fits a linear regression rather well with a significantly positive trend.
The RSS satellite's orbit could continue to decay and
the RSS trend could continue to be the outlier.
RSS satellite data sets were first published in 2001; by July, 2004,
the RSS trend stood at 0.13 °C per decade.
In fact, the UAH data from January 1998 through present (April 2007) is (a non-significant) 0.072 ºC / decade and
the RSS trend for the same period is (a non-significant) 0.012 ºC / decade (overall, from the start of the record until now, the UAH and RSS global lower tropospheric trends are (a significant) 0.15 ºC / dec and 0.18 ºC / dec, respectively).
No, you are wrong, RSS is consistent with models only if we look at global trends, but
RSS trend for tropical «hot - spot» is out of 2 standard deviations limit of the model mean, just like UAH and all «uncorrected» radiosonde data sets.
RSS trend for 1979 - 2004 is outside 2 sd of model mean (see Douglas et al 2007, figure 1)(why do you use 1979 - 1999 period?).
RSS trends are actually negative since 1988.
The RSS trends are just within the range of model solutions
Also, the size of the difference in the UAH 5.6 and
RSS trends suggests someone is doing something wrong.
RSS trends showing the millennial cycle temperature peak at about 2003 (14) Figure 4 illustrates the working hypothesis that for this RSS time series the peak of the Millennial cycle, a very important «golden spike», can be designated at 2003.
I'm not sure there's much point asking for comments about the general discrepancy between UAH and
RSS trends, as this has been known for some time and appears to be largely related to inter-satellite calibration issues.

For 1979 - 1999, the model's tropical T2
trends are 0.2 + / - 0.26 (95 %),
RSS is 0.14 + / - 0.26, for T2LT, models 0.22 + / - 0.26,
RSS: 0.17 + / - 0.26 (95 % CI, corrected for temporal autocorrelation).
It is much better to use both UAH and
RSS, or HadCRUT and GISTEMP (and NCDC) than it is to simply pick the one that gives you the
trend or character you prefer.
That's about to be the record showing the lowest
trend, once
RSS implements their newly - corrected algorithm in the TLT product.
The UAH data is showing a decreased
trend, similar to
RSS in timing, but less in magnitude.
«Using the [cherry flavored &; >)
RSS data, which Santer used in determining his 17 - yr minimum time needed for a human global warming signal, the most recent 17 - yr

I thought he might be unhappy to see: — the adjustment (in the new paper) losing the 1998
RSS high temp shown in Zeke Hausfather's older graph, so the «cooling
trend» argument gets hurt, or — the newer graph having one more recent data point than the older, so the «cooling
trend» argument gets hurt, or — the newer graph showing a shorter time span and so not showing the lower temps in earlier decades, so the «cooling
trend» argument gets hurt, or — the newer graph isn't directly comparable to an older graph he prefers to look at without thinking about the numbers along the side, or — I du n no.
As far as I know, the 2 main sources of satellite data for temperatures in the lower troposphere are UAH and
RSS, and they vastly differ in their
trends in the tropical troposphere, with
RSS's
trend being twice as warming as the UAH
trend, although they show the same
trends in the remaining troposphere, resulting in a Global difference of only 0.035 C / d
trend.
So you want to say that flat
trend since 1996/97, according both UAH and
RSS, is consistent with models?
My figure b agrees with Dan's observation that for
RSS the recent
trend is the lowest — .
On your further claim that the
RSS data is consistent with the models, please provide us with GISS plots of the tropospheric and lower stratospheric layer average temperature data
trends (corresponding to their weighting functions TLS; TTS; TMT and TLT).
If one plots the records from GISS, HADCru,
RSS and UAH; GISS is the outlier, and three of the four primary global temperature measuring systems show a decrease over the most recent six years and a downward
trend over the past decade; not that this establishes a significant
trend yet.
In this conversation you cite unceratinty of
RSS data that are almost twice larger than
trend (+ -0,26), although Mears and Weinz (2005) state that error range of
RSS T2LT is 0.09!!!
or
RSS showing the lowest 17 - yr
trend ever?
Yes, you have read correctly, the published official
trend of UAH ignores the first two years of data, and so does
RSS.
Tropical SST
trends in HadISST are 0.1 deg C / dec, HadCRUT3v 0.11 deg C / dec,
RSS T2LT is 0.17 deg C / dec.
The way to transform it into temperatures is unclear enough as to give temperature
trends from UAH and
RSS that differ in 0.035 C per decade.
In their
trend from 1998, the two satellite series contradict each other: UAH shows +0.05 ° C per decade (a bit more than HadCRUT4),
RSS shows -0.05 ° C per decade.

The current differences between S+C 2LT (v5.2) and
RSS 2LT
trends are large precisely because of this.
One estimate of that error for the MSU 2 product (a weighted average of tropospheric + lower stratospheric
trends) is that two different groups (UAH and
RSS) come up with a range of tropical
trends of 0.048 to 0.133 °C / decade — a much larger difference than the simple uncertainty in the
trend.
The new
RSS version of the 2LT record still shows a higher
trend (0.19 deg / decade), with the difference being due to the methodology used to splice the different satellites.
RSS now shows a 207 month period with 0.0
trend.
But the more basic point here is that the Cowtan paper does not use the satellite time
trend (which is somewhat unreliable — remember the long history of corrections, and the difference in
trends between the UAH and
RSS products), it only uses the satellite spatial pattern to fill the data holes.
Third, the
trend for the entire
RSS MSU data set is 0.18 + / - 0.06 K / decade.
So, concerning solar factor, their results confirm what we allready know from UAH and
RSS cooling
trends for stratosphere 1979 - onward.
To tamino # 135 — I'm guessing you rounded the figures from
RSS while I used all the data and a statistical package to derive the
trend.
Over the area that these cover, the satellite data
trends in UAH and
RSS are pretty much the same, thus verifying the data extraction algorithms of the satellite temp series.
It says in the abstract that models overestimate warming in the troposphere, and in the main text «The multimodel average tropospheric temperature
trends are outside the 5 — 95 percentile range of
RSS results at most latitudes.»
As the science continues to mount up against AGW (i.e. latest Aqua satellite data supporting «negative» feedback and GISS, UAH,
RSS, Hadley data showing no warming since 1998 and a
trend towards cooling), I see «doubters» getting rounder and rounder, and Pachauri, Gore, Hansen, et al getting flatter and flatter.
GISS, HadCRUt3,
RSS and UAH all show no statistically significant
trend in mean gobal temperature at 95 % confidence limits for the most recent 15 years.
Of course, everyone likely knows by now that the big news of late has been the v4 update to the
RSS satellite data set, which raised the
trend in their data by about 60 %.
If you plot satellite data (UAH or
RSS) over same years there is no
trend to speak of after a margin of error is included.
