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 ...

How to achieve maximum data consistency and meet the needs of data users? The options available to the Terra project for using its remaining fuel expanded when the altitude-lowering criteria for ...

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 ...

For 25 years, NASA’s Flagship Earth Observing System satellite, Terra, has collected daily morning Earth observations using five different instruments: ASTER, CERES, MISR, MODIS, and MOPITT.

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 ...

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 ...
