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 ...
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 ...
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 ...
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 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, ...
