In advance of my September 2018 global surface and lower troposphere temperature anomaly update, this is a very quick introduction to the new (over a year old) lower troposphere temperature anomaly data from RSS (Remote Sensing Systems)…just three graphs.
As you likely know, I haven’t published a monthly global temperature update in almost 2 years. Since then, in July 2017, RSS released their version 4.0 lower troposphere temperature (TLT) anomaly data. See the RSS webpage FAQ about the V4.0 TLT Update for more insights.
While preparing this month’s global temperature update, I downloaded the new global RSS TLT version 4.0 data for the first time and compared it to the UAH TLT data and to the three surface temperature datasets from NASA GISS, NOAA NCEI and the UKMO Hadley Centre—with all datasets starting in January 1979 and all referenced to the base years of 1981-2010. The new RSS TLT data shocked me, to say the least. (Expletives deleted.) See Figure 1.
Figure 1
Note that, from January 1979 to October 2018, the new RSS TLT warming rate is even higher than all three surface temperature datasets. Un-flip-flopping-believable!
That prompted me to compare the global (70S-85N) RSS TLT data version 3.3 data (still available here) to the new version 4.0 data (available here). See Figure 2. As illustrated, the new data has a noticeably higher warming rate. I actually said, “Wow!” aloud when EXCEL produced the graph.
Figure 2
And for anyone interested, Figure 3 presents the difference between the two RSS TLT datasets with the version 3.3 data subtracted from the version 4.0 data.

WHAT DR. ROY SPENCER HAD TO SAY!
Dr. Roy Spencer, co-author of the lower troposphere temperature anomaly dataset from UAH, published a couple of posts about the new RSS TLT data.
- Comments on the New RSS Lower Tropospheric Temperature Dataset, which was cross posted at WattsUpWithThat here.
- Warming in the Tropics? Even the New RSS Satellite Dataset Says the Models are Wrong
COMMENTS ABOUT THE NEW RSS TLT DATA, ANYONE?
I have a funny feeling this post will generate a couple of comments…hmmmm probably lots of comments at WUWT. Have fun!!!
That’s it for now. I’ll publish the full monthly update very soon. It’s almost ready. I just have to rewrite the text for the RSS data. Oy! I’ll try to remain civil.
STANDARD CLOSING REQUEST
Please purchase my recently published ebooks. As many of you know, this year I published 2 ebooks that are available through Amazon in Kindle format:
- Dad, Why Are You A Global Warming Denier? (For an overview, the blog post that introduced it is here.)
- Dad, Is Climate Getting Worse in the United States? (See the blog post here for an overview.)
Be back soon.

Just out of curiosity I made this graph. I was looking for the closest temperature dataset to UAH and RSS. Something changes around 2002.
As a scientist, I must say that I only believe my own results which show we are cooling, looking at minimum temperatures:
Reblogged this on Climate Collections.
Bob have you looked at HAD Crut 4 data since Dr Jones’s BBC Q&A in 2010? Any comments?
I’ve checked the HAD Crut 4 temp trends before, but it seems to have changed a lot since Phil Jones’s Q&A with the BBC in 2010, after the Climategate scandal.
In 2010 he listed 4 warming trends since 1850 and there wasn’t much difference in the trends. The 4 trends were—-
1860 to 1880- 0.163c dec
1910 to 1940- 0.150 dec
1975 to 1998- 0.166 dec
1975 to 2009- 0.161 dec.
Today the York Uni tool has the SAME 4 trends for Had 4 Crut at—–
1860 to 1880- 0.156c dec lower
1910 to 1940- 0.137 dec lower
1975 to 1998- 0.191 dec much higher
1975 to 2009- 0.193 dec. much higher
So just 8 years after Jones’s BBC Q&A we see both earlier warming trends have been adjusted down and the two later trends have been adjusted up. And people wonder why we don’t trust these temp data-sets?
And this is the temp data-set that the IPCC uses to try and convince us to waste endless billions $ for zero gain. Who are they trying to fool? And why hasn’t one of their top scientists noticed this and blown the whistle?
Here’s Dr Jones’s 2010 BBC Q&A. See question A.

Here’s the YORK UNI tool using HAD 4 Crut krig global.
Sorry here’s the York uni software. I hope you can find time to look at this Bob?http://www.ysbl.york.ac.uk/~cowtan/applets/trend/trend.html
What’s landed me in moderation?
ngard2016, thanks for the links. I approve all comments here. There aren’t that many.
Sorry for the delay. I spent the day in the yard…lots of leaves this time of year, a plethora of them..

Hi Bob,
I just thought I’d let you know that I’ve been downloading complete sets of RSS and UAH temperature data month by month for a few years now. I do this because I decided to monitor the Gosselin-Honeycutt climate bet which they agreed would be based on the average of those two series.
I store all the spreadsheets which contain all the downloaded data in my Google Drive. Links to the downloadable spreadsheets are available at this page.

Cheers and keep well,

Robin.
Thanks, Robin.
Cheers,
Bob
Same story. Looking at data for even up to a century does not reflect what is going on
with Earth’s climate. Only the life of Earth, over 4 billion years is a reasonable baseline
for temperature changes and climate changes on Earth. Which means geologists who
have studied temperature and climate changes as far back as they dare are the only
ones with a reasonable picture of what is going on with temperature and climate. Just because the relevant data is earlier than human measurements does not change what went on before human measurements; which is important in understanding what the range of Earth climate and temperatures has been on Earth; and what humanity needs to be prepared to deal with.

Hi bob i am in india, and focus on agriculture, the weather has a huge impact on crop and hence very keen to know how we can get the data sets which can help us get greater understanding of impact of weather , ie if we can get some weather data sets based on lat long etc for india
ravishankar mantha, I use the KNMI Climate Explorer:
https://climexp.knmi.nl/start.cgi
They have a good number of datasets under the heading of “Monthly Observations” that are available by entering the latitudes and longitudes you desire.
Regards
Bob
ravishankar mantha, regarding recent request,
sorry, I don’t exchange email addresses with people I do not know.

Bob

I deeply appreciate your views. only thing is that we are trying to see how well we can use open source weather data to incorporate its impact on the Indian agricutlure. As a startup , we want to be away from paying to any large entity. We want to use your help to address the domestic agriculture issues specially since weather has a large bearing on the small farmers. Trust you would understand our challenge.
ravishankar mantha, I am not the person you need.
Sorry,
Bob
ravishankar mantha, In answer to your most recent and unpublished comment, I tried to be nice with my prior answer. Let me make this very clear.
I will not do it. You are wasting your time pursuing me. Fine someone who is local to you to help you.
Good-bye
Understood, point taken. my apologies, though never meant to hurt. always look forward to reading your research.
