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 ...

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 ...

Summer rains have swollen rivers throughout northeastern China, including the Songhua River. Water levels peaked in Harbin on August 27 and have remained high. The Songhua River is one of many ...

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 ...

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, ...

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 ...

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 ...

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.

In early April 2013, clouds stretched in parallel rows for hundreds of kilometers over the Bering Sea. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this ...

A dust storm blew out of Libya and across the Mediterranean Sea in late March 2013. Southwest of the coastal city of Banghazi (Benghazi), an especially thick dust plume spanned roughly 100 kilometers ...
