NASA's Aura Satellite measures pollution from New Mexico, Arizona fires

04.07.2011
NASA's Aura Satellite has provided a view of nitrogen dioxide levels coming from the fires in New Mexico and Arizona. Detecting nitrogen dioxide is important because it reacts with sunlight to create low-level ozone or smog and poor air quality.

The fierce Las Conchas fire threatened the town and National Laboratory in Los Alamos, while smoke from Arizona's immense Wallow Fire and the Donaldson Fire in central New Mexico also created nitrogen dioxides (NO2) detectable by the Ozone Measuring Instrument (OMI) that flies aboard NASA's Aura satellite.

An image showing nitrogen dioxide levels from June 27 to 29, 2011 was created from OMI data using the NASA Giovanni system by Dr. James Acker at NASA's Goddard Space Flight Center in Greenbelt, Md. The highest levels of NO2 were from the Las Conchas fire. The NO2 is measured by the number of molecules in a cubic centimeter.

Low-level ozone (smog) is hazardous to the health of both plants and animals, and ozone in association with particulate matter causes respiratory problems in humans.

On July 1, Inciweb reported that the Las Conchas fire is currently burning on 93,678 acres and was three percent contained. An infrared flyover at 4 a.m. MDT on July 1 reported 103,842 acres burned. InciWeb is the "Incident Information System" website that reports wildfire conditions throughout the country.

The Donaldson fire is estimated to cover 72, 650 acres and is located to the southeast of the Las Conchas fire. Inciweb reported on July 1 that the fire is burning in the Lincoln National Forest and Mescalero-Apache Tribal lands and is not accessible. The terrain is steep and rocky. It is located about 10 miles northwest of Ruidoso Downs, N.M.

Inciweb reported on July 1 that "smoke from the fire is impacting the communities of Ruidoso, Ruidoso Downs, Capitan, Lincoln, Hondo, Fort Stanton, Picacho, Tinnie, San Patricio, Glencoe and other surrounding areas." In east central Arizona, the Wallow Fire is now 95 percent contained, according to InciWeb. Total acres burned are 538,049, including 15,407 acres in New Mexico.

Emissions from coal-burning power plants located in northwest New Mexico were also visible in the image.

OMI data is archived at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), and is provided by KNMI, the Koninklijk Nederlands Meteorologisch Instituut (Royal Netherlands Meteorological Institute). Dr. P.F. Levelt is the Principal Investigator of OMI, Dr. J. Tamminen is the Finnish Co-PI, and Dr. P.K. Bhartia leads the U.S. OMI science team. Dr. James Gleason (NASA) and Pepijn Veefkind (KNMI) are PIs of the OMI NO2 product.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
