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 ...

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 ...

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 ...

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 ...

This article from IEEE talks about how satellite data can predict agricultural output and famine. Terra plays a large role in measuring the National Data Vegetation Index (NDVI), which is measured ...

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, ...

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 ...

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, ...

The Science Team Leader for ASTER, Dr. Yasushi Yamaguchi, is a professor at the Graduate School of Environmental Studies, Nagoya University, Japan. He graduated Tohoku University, Japan, and obtained ...

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 ...
