Fundamentals of Remote Sensing – An interactive online tutorial on remote sensing technology and its applications from the Canada Centre for Mapping and Earth Observation, Natural Resource Canada.

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 ...

The CERES website informs a broad audience about CERES data and products. The CERES team has been collecting ERB data since 1997, when the first CERES instrument was launched aboard the Tropical ...

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 ...

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 ...

Terra by the numbers – Click on image to enlarge. Terra’s different science focus areas. Each circle size represents the relative number of data products in each of these science areas. – Click on ...

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 ...

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 ...

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 ...

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 ...

It’s all a matter of perspective: measuring rain from the ground. Citizen scientists can contribute much to the understanding of rainfall patterns by reporting precipitation totals at their location.

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, ...
