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 ...
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 ...
MODIS website informs a broad audience about MODIS data and products. The MODIS instrument is operating on both the Terra and Aqua spacecraft. It has a viewing swath width of 2,330 km and views the ...
When energy from the Sun reaches the Earth, it warms the atmosphere, land, and ocean and evaporates water. The movement of water from the ocean to the atmosphere to the land and back to the ocean—the ...
Carbon is a fundamental part of the Earth system. It is one of the primary building blocks of all organic matter on Earth and a key element in setting Earth’s temperature. Carbon moves from the ...
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 ...
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 ...
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 ...
Terra collects data about the Earth’s bio-geochemical and energy systems using five sensors that observe the atmosphere, land surface, oceans, snow and ice, and energy budget. Each sensor has unique ...
No matter where you live-along the coast, in the heartland, or somewhere in between-your life is affected by water quality. Water quality issues raise many questions that are important to us all at ...
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 ...
