To improve air quality, it is important to know what contributes to polluting the air. Haze comes from a variety of sources. Your skies may be hazy from local traffic, or industry such as for example ...

Forecasts indicate that Japan can expect widespread rain as Typhoon Phanfone nears the nation over the weekend. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite ...

In June of 2016, Dr. Helen Worden became the U.S. Principal Investigator for MOPITT. She is interested in multi-decadal trends of carbon monoxide that indicate changing emissions of pollution with ...

If you live in the northern hemisphere, the past few weeks have been strange. In places where it should be seasonably hot—the eastern and southern United States and western Europe—it’s just been warm.

The winter of 2013–2014 was a study in contrasts between mountains in the far western United States and in the interior West. While people waited in vain for winter snow in California and the Pacific ...

A layer of haze filled China’s Sichuan Basin on January 23, 2014, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image. The haze ...

Rarely do weather patterns and satellite overpass schedules align to provide cloud-free views of Western Europe in the spring. However, a high-pressure pattern kept skies spectacularly clear over the ...

Testing for nitrogen in your local watershed can help identify potential “œhot spots” in your community that may be contributing to nutrient loading downstream. With a simple, inexpensive field test ...

A wall of dust was barreling across northern China on April 23, 2014, when the Moderate Resolution Imaging Spectroradiometer (MODIS) acquired these images from NASA’s Aqua and Terra satellites. The ...

The map above shows land surface temperature anomalies in North America for January 1-7, 2014. Based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, ...

The Science Team Leader for ASTER, Dr. Yasushi Yamaguchi, is a professor at the Graduate School of Environmental Studies, Nagoya University, Japan. He graduated Tohoku University, Japan, and obtained ...

There are many ways to gauge air quality. The most common measure is visibility, since most of the constituents of air pollution form visible haze. You can use your own observations and a digital ...
