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 ...
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 ...
Between late November 2012 and early January 2013, China recorded its lowest temperatures in 28 years. In northeastern China, air temperatures dipped to -15.3°Celsius (4.5°Fahrenheit), according to ...

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 ...
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 ...
Nutrients such as nitrogen and phosphorous are not directly measurable with satellite observations. However, satellites can measure chlorophyll concentration, which can act as somewhat of a proxy for ...
When the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA’s Terra satellite passed over northern Minnesota on May 12, 2013, spring had transformed winter’s snowy white ...
On July 27, 2013, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of the Mile Marker 28 fire burning about 15 miles northeast of Goldendale, ...
It’s all a matter of perspective: measuring rain from the ground. Citizen scientists can contribute much to the understanding of rainfall patterns by reporting precipitation totals at their location.
