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 ...

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 ...

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 ...

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 ...

Terra has consistently orbited Earth from Pole to Pole for over twenty years, collecting important data about Earth’s systems. Crossing the equator at 10:30 am mean local time allowed Terra’s five ...

Climate is the sum of weather over time, the average temperatures and rainfall of a place. Earth’s climate—how hot our planet is on average—is set by the Sun. Anything that changes the amount of solar ...

Dr. Nyssa Rayne is an Outreach Coordinator on contract at NASA Goddard Space Flight Center through Global Science and Technology. She manages the Terra Mission website, providing the public with ...

ASTER website informs a broad audience about ASTER data and products. ASTER data are are available from several archives: ...

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 ...

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 ...
