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 ...
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 ...
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 ...
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 ...
Posted on September 19, 2013 by Sciencecodex.com The MODIS instrument, or Moderate Resolution Imaging Spectroradiometer aboard NASA’s Terra satellite captured an amazing image of Typhoon Usagi on Sept ...
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 ...
As most data users are aware, the Terra satellite has recently been experiencing power-based limitations caused by orbital changes and solar array efficiency. In order to maintain power margins, the ...
A low-pressure system brought strong winds—gusting to 55 miles (85 kilometers) per hour —to the Southern Plains on March 18, 2014. The winds picked up exposed soil from the parched landscape, ...
