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 ...

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 ...

How successfully do rain gauges catch rainfall patterns? Do the satellites record the same patterns of data as the ground-based gauges? How many gauges are required in order to observe regional ...

For many residents of North America, the winter of 2013-14 has felt like one of the coldest in many years. Waves of Arctic air brought extended periods of cold weather and above-average snowfall to ...

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 ...

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.

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 ...

China suffered another severe bout of air pollution in December 2013. When the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image on December 7, 2013, ...

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, ...

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 ...

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 ...

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this image of farmland near LaCrosse, Washington, on July 24, 2008. The false-color image ...
