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: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
