Roy Spencer’s Blog June 9th, 2021 by Roy W. Spencer, Ph. D. HadCRUT5 shows 14% more global warming since 1850 than HadCRUT4 – Watts Up With That? By Christopher Monckton of Brenchley They’re at it again.
The old lady of temperature datasets – HadCRUT, the only global dataset to reach back to 1850 – has released its revised monthly global mean surface temperature anomalies for 1850-2020.

Roy Spencer’s Blog April 23rd, 2019 by Roy W. Is Satellite Altimeter-based Sea Level Rise Acceleration from a Biased Water Vapor Correction? SUMMARY: Evidence is presented that an over-correction of satellite altimeter data for increasing water vapor might be at least partly responsible for the claimed “acceleration” of recent sea level rise.
UPDATE: A day after posting this, I did a rough calculation of how large the error in altimeter-based sea level rise could possibly be. The altimeter correction made for water vapor is about 6 mm in sea level height for every 1 mm increase in tropospheric water vapor. The trend in oceanic water vapor over 1993-2018 has been 0.48 mm/decade, which would require about [6.1 x 0.48=] ~3 mm/decade adjustment from increasing vapor.
Weather satellite wanders through time, space, causing stray warming to contaminate data. In the late 1990s, the NOAA-14 weather satellite went wandering through time and space, apparently changing the record of Earth's climate as it went.
Designed for an orbit synchronized with the sun, NOAA-14's orbit from pole to pole was supposed to cross the equator at 1:30 p.m. on the sunlit side of the globe and at 1:30 a.m. on the dark side, 14 times each day. One of the instruments it carried was a microwave sounding unit (MSU), which looked down at the world and collected data on temperatures in Earth's atmosphere and how those temperatures changed through time. UAH finds a warming error in satellite data, lowers “tropical hotspot” temperature trend, contradicts IPCC models. From the University of Alabama, Huntsville via email from Dr.

Roy Spencer On Satellite v Surface Data. By Paul Homewood With the continuing divergence of surface and satellite temperature records, it is worth revisiting what Roy Spencer had to say on the issue in 2014: Much is being made of the “global” surface thermometer data, which three-quarters the way through 2014 is now suggesting the global average this year will be the warmest in the modern instrumental record.
I claim 2014 won’t be the warmest global-average year on record. ..if for no other reason than this: thermometers cannot measure global averages — only satellites can. Mystery solved: Rain means satellite and surface temps are different. Climate models didn’t predict this… A funny thing happens when you line up satellite and surface temperatures over Australia.
A lot of the time they are very close, but some years the surface records from the Australian Bureau of Meteorology (BOM) are cooler by a full half a degree than the UAH satellite readings. Before anyone yells “adjustments”, this appears to be a real difference of instruments, but solving this mystery turns up a rather major flaw in climate models. Bill Kininmonth wondered if those cooler-BOM years were also wetter years when more rain fell. So Tom Quirk got the rainfall data and discovered that rainfall in Australia has a large effect on the temperatures recorded by the sensors five feet off the ground.
