07.04.2011
Global Temperature Report: March 2011

Global climate trend since Nov. 16, 1978: +0.14 C per decade

March temperatures (preliminary)

Global composite temp.: -0.10 C (about 0.18 degrees Fahrenheit) below 30-year average for March.

Northern Hemisphere: -0.07 C (about 0.13 degrees Fahrenheit) below 30 year average for March.

Southern Hemisphere: -0.13 C (about 0.23 degrees Fahrenheit) above/below 30-year average for March.

Tropics: -0.35 C (about 0.63 degrees Fahrenheit) below 30-year average for March.

February temperatures (revised):

Global Composite: -0.02 C below 30-year average

Northern Hemisphere: -0.04 C below 30-year average

Southern Hemisphere: ±0.00 C above/below 30-year average

Tropics: -0.35 C below 30-year average

(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)

Notes on data released April 5, 2011:

Driven by the La Nina Pacific Ocean cooling event, global average temperatures in March 2011 were the coolest March since 1999, according to Dr. John Christy, professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville.

It was the fifth coolest March in the tropics, where the average temperature fell 0.35 C (about 0.63 degrees Fahrenheit) below seasonal norms. Three of the five coldest tropical Marches in the 33-year satellite temperature record have happened in the past dozen years: 5th, 2011, -0.35 C: 3rd, 2000, -0.42; and 2nd, 2008, -0.58 C.

As part of an ongoing joint project between UAHuntsville, NOAA and NASA, Christy and Dr. Roy Spencer, a principal research scientist in the ESSC, use data gathered by advanced 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 where 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 Christy nor Spencer 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 federal and state grants or contracts.

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...
