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 ...

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 ...

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 ...

At approximately 6:45 a.m. on April 18, 2014, a block of ice tumbled from the edge of a hanging glacier onto a popular climbing route on the south face of Mount Everest. The ice, which weighed as much ...

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 ...

On January 6, 2014, the Moderate Resolution Imaging Spectroradiometer MODIS on NASA’s Terra satellite captured this natural-color image (top) of fog forming over the lakes and streaming southeast with ...

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 ...

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 ...

The natural-color satellite image below offers both a modern and historical context. Captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, it shows heavy ...

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, ...
