Jennifer Marohasy on TNTRADIO.LIVE: Mercury Thermometers Versus Probes in Automatic Weather Stations

I will be talking about these issues this afternoon on TNT radio with the legendary Chris Smith.

Uncertainty Estimates for Routine Temperature Data Sets Part Two.

In short, what is the proper magnitude of the uncertainty associated with such routine daily temperature measurements?

Systemic Error in Global Temperature Measurement

The result is a reduction of the temperature change between the decades 1880-1890 and 2010-2020 from 1.43°C to 0.83°C CI(95%) [0.46°C; 1.19°C].

BOM Buries Record Daily Rainfall During Lismore Floods

Curiously this 24-hour rainfall total, what should be recognised as a new 24-hour rainfall record for Lismore of 467 mm, has not been entered into any of the official reports or into…

Uncertainty Estimates for Routine Temperature Data Sets

Modern climate research commonly fails adequate recognition of three guiding principles about uncertainty.

UN: “The World is Going to End” – Kink Analysis Says Otherwise

This technique will identify a curved line (such as a logarithmic curve) as having a kink. Also, at this point I have no statistical method by which to place a…

Monitoring Arctic Permafrost with Satellites, Supercomputers, and Deep Learning

“The ice wedges form from the freezing and melting of soil in the tundra,” said Liljedahl. “Some of them are tens of thousands of years old.”

Claim: Air Bubbles Sound Climate Change’s Impact on Glaciers #ASA181

“Recording the underwater sounds from a melting terminus will open the door to long-term acoustical monitoring of ice loss, and how it is linked to water temperature,” said Deane. “The…

Claim: Climate Change is Making One of the World’s Strongest Currents Flow Faster

Study co-authors said it is also likely that the speed of the current will increase even more as the Southern Ocean continues to take up heat from human-induced global warming. 

The U.S. Could Have Wildfire Smoke Radar

Imagine the ability to determine the three-dimensional distribution of wildfire smoke across the United States in real-time.

An Unmanned Saildrone Takes Weather Observations in the Center of a Hurricane

On Thursday, September 30, an autonomous (unmanned) sailboat, called a Saildrone, made it into the center of Hurricane Sam, a category four tropical cyclone, measuring extraordinary winds and seas.  

A song of ice and fiber

This is the first time a distributed acoustic sensing interrogator system had been used to capture data on the seafloor of the Arctic or Antarctic oceans, and the team sees…

Broken Water Pipe Takes Out U.S. Buoy Data

A broken pipe and flooding has closed down a key NOAA data facility in Silver Spring, Maryland, and there is no estimate of when this data source will become available.…

The Revolutionary Weather Observers

Reposted from the Cliff Mass Weather Blog It is not well known that the founders of the American republic were avid amateur meteorologists, with many of them taking weather observations…

Preparing the Sentinel-6 Michael Freilich Satellite for Launch

A U.S.-European partnership, the Sentinel-6 Michael Freilich spacecraft will begin a five-and-a-half-year prime mission to collect the most accurate data yet on global sea level and how our oceans are…

Caution: Pretty Pictures Can Fool You

Guest Essay by Kip Hansen   In today’s digital and Internet-of-Things  world, it is easy to transform information into images — graphs, charts and other visuals that are colorful and…

In Search of the Standard Day

By Dr Fabio Capezzuoli Recent posts and discussions on WUWT regarding air temperature sampling frequencies and their influence on the daily average – propagating to monthly and yearly trends – demonstrated…

Sharpening a Cyclical Shovel

Guest Post by Willis Eschenbach There are a number of lovely folks in this world who know how to use a shovel, but who have never sharpened a shovel. I’m…

Weather Observers Misread Wind Speeds, Skewing a Major Hazards Database

Weather spotters who report storm measurements and observations to a U.S. national compendium of storm data often exaggerate winds speeds—by about one third, on average. By Elizabeth Deatrick  EOS.org People…

Mauna Loa Daily Meteorology

Guest Post by Willis Eschenbach As a confirmed data junkie, I’m fond of hourly data. The interesting processes in the climate system unfold on the scale of minutes and hours,…

What Are They Really Counting?

Guest Essay by Kip Hansen WARNING: This is not a technical essay. There is almost no science in it. It is not about AGW or any issue involved in the…

Are We Chasing Imaginary Numbers?

Guest Essay by Kip Hansen    Spoiler Alert: This essay is not about the mathematical entity the imaginary number. I do think that an essay here about imaginary numbers of…

Approximately 92% (or 99%) of USHCN surface temperature data consists of estimated values

An analysis of the U.S. Historical Climatological Network (USHCN) shows that only about 8%-1% (depending on the stage of processing) of the data survives in the climate record as unaltered/estimated data.…

Winners and losers in the GHCN estimation derby

Guest essay by John Goetz As noted in an earlier post here, approximately 66% of the GHCN record is estimated after processing by the GHCN adjustment models. In the current…
