Global Temperature Report -- October 2009

19.11.2009
An El Nino Pacific Ocean warming event that caused the second warmest tropical October in 31 years didn't stop the continental U.S. from seeing its second coldest October in that same time, according to Dr. John Christy, professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville. The National Oceanic and Atmospheric Administration reported that October 2009 was the third coldest October in the continental U.S. since 1895.

The only October in the past 31 that was warmer in the tropics than last month was October 1987, when the average temperature in the tropics was 0.53 C (about 0.95 degrees Fahrenheit) warmer than seasonal norms. The October 2009 average temperature in the tropics was 0.33 C (about 0.6 degree Fahrenheit) warmer than seasonal norms.

At the same time, the average temperature over the 48 contiguous states was 1.45 C (about 2.61 degrees Fahrenheit) cooler than seasonal norms for October. The coldest October in the past 31 was in 2002, when average temperatures dropped 1.48 C (about 2.66 degrees Fahrenheit) below normal. By comparison, the next coldest October was in 2006, when temperatures in the continental U.S. were only 0.8 C cooler than normal.

Global climate trend since Nov. 16, 1978: +0.13 C per decade

October temperatures (preliminary)

Global composite temp.: +0.28 C (about 0.50 degrees Fahrenheit) above 20-year average for October.

Northern Hemisphere: +0.27 C (about 0.49 degrees Fahrenheit) above 20-year average for October.

Southern Hemisphere: +0.30 C (about 0.54 degrees Fahrenheit) above 20-year average for September.

September temperatures (revised):

Global Composite: +0.42 C above 20-year average

Northern Hemisphere: +0.55 C above 20-year average

Southern Hemisphere: +0.29 C above 20-year average

(All temperature variations are based on a 20-year average (1979-1998) for the month reported.)

As part of an ongoing joint project between The University of Alabama in Huntsville, NOAA and NASA, Christy and Dr. Roy Spencer, a principal research scientist in the ESSC, use data gathered by microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas for which reliable climate data are not otherwise available.

The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a "public" computer file for immediate access by atmospheric scientists in the U.S. and abroad.

Neither Spencer nor Christy receives any research support or funding from oil, coal or industrial companies or organizations, or from any private or special interest groups. All of their climate research funding comes from state and federal grants or contracts.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
