Tuesday (14), Atmospheric physicists and NASA employees explain how TIME worksIt is an acronym for “Tropospheric Emissions: Pollution Monitoring”, a new spacecraft in the final stages of deployment that promises to be a decisive step in monitoring atmospheric pollution in North America.

TIME, according to NASA, “It is an ultraviolet and visible spectrometer to be housed on the Intelsat 40e., a commercial satellite built by Maxar Technologies. “TEMPO’s sensors will enable it to observe the spectral signatures of air pollutants, including ozone and nitrogen dioxide, by measuring sunlight reflected and scattered by the Earth’s surface and atmosphere.”

The result of a partnership between the US space agency and the Smithsonian Astrophysical Observatory, TEMPO will be on a stationary satellite, meaning it stays in a fixed position relative to the Earth’s surface. Working during the day, it will observe sunlight reflecting into Earth’s atmosphere and provide subsidies for scientists to identify present pollutants and their locations.

What does TEMPO offer again?

The big difference of TEMPO compared to traditional satellites This is because scientists can observe emissions around the clock throughout the day. “The satellites we currently use orbit the Earth about 14 to 15 times a day, about 700 kilometers above the surface,” said Harvard & Smithsonian physicist Caroline Nowlan at the presentation.

This orbital mobility means that each of these spacecraft passes a specific point on Earth at the same time of day, providing a single daily measurement, usually at the same time of day. TIME revolves “with the planet”that is, it shows a large variability of pollution at small scales. This can be done both in big cities like New York and in small urban areas in North America.

As different gaseous emissions take on characteristic colours, the device’s ultraviolet light detectors will allow scientists to concentrate on three polluting gases: nitrogen dioxideassociated with the onset of asthma; ozonebeneficial in the stratosphere but harmful to underground crops; and formaldehydeIt’s a byproduct of fossil combustion and a carcinogen, according to the American Cancer Society.
