The Ocean’s Carbon Balance NASA Earth Observatory

And in late 2008, NASA will launch the Orbiting Carbon Observatory, which will track the abundance and distribution of carbon in the atmosphere. The technology has evolved over the past decade as scientists realized that to understand the ocean carbon cycle, they are going to have to look for the human fingerprint in ocean circulation and biology, not just in ocean chemistry. “When I started ...

Carbon Dioxide Sources and Sinks Activity | UCAR Center ...

Carbon dioxide (CO 2) is an important gas in our atmosphere and is part of a natural biogeochemical activities, like burning fossil fuels, also emit CO 2 into the atmosphere. The amount of CO 2 in the atmosphere is increasing because of human activities, which have an impact on global climate. In this lesson, students will investigate some of the ways CO 2 gets into and out of the ...

Sick Classrooms Caused by Rising CO2 Levels

· Sick Classrooms Caused by Rising CO2 Levels. “Exposure to CO2 can result in drowsiness, eye irritation, and inability to concentrate. If a ventilation system provides inadequate freshair intake, levels of CO2 in the classroom can rise dramatically during the course of a classroom session.”. Brian W. Smith.

CO2 Control In School Classrooms AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that overventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...

Suggested CO Control Sequence Of Operation

2 Control Sequence Of Operation Installation Coverage: One sensor should be used for each zone of major occupancy or per air handling device if a number of devices serve a large zone. If occupancy density/patterns/usage are different in two adjacent areas each area should be considered a separate zone. Generally one sensor can serve up to 5,000 sq feet. Larger coverage is possible in theaters ...

The 2019 Guide to Demand Control Ventilation

· Carbon dioxide (CO2) is an excellent indicator of occupancy, since all human beings produce similar amounts per hour. In addition, a DCV system with CO2 concentration sensors can tell not only the total occupant load, but also how they are distributed among indoor spaces. This way, the ventilation system can control the total airflow provided, and also how it is split among various zones.
