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 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, ...
Torrential rain brought deadly floods to southern Brazil and Paraguay in June 2014. The top image, acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite on ...
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 ...
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 ...
A layer of haze filled China’s Sichuan Basin on January 23, 2014, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image. The haze ...
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 ...
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 Terra Science Team welcomes any feedback or suggestions as to whether to maintain the current orbit and the long-term data continuity, or lower the orbit, and therefore, shifting the crossing time ...
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 ...
Air flows like water in the atmosphere with invisible currents and waves. On April 9, 2014, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this view that ...
