Eddy covariance
Imagine you're standing in the middle of a big field and want to know how much air and gas particles (like carbon dioxide) are coming in and out of it. Eddy Covariance is a tool that helps us measure this exchange between the field and the air.
There's a device set up nearby that has a tall pole with instruments on it. These instruments can measure the wind speed, temperature, pressure, and humidity. They're all really important because the amount of air and gas particles moving in and out of the field depends on these factors.
As these air and gas particles come in and out of the field, they create swirling patterns called "eddies." The instruments on the pole are specifically designed to measure these eddies. They measure the amount of gas being exchanged between the field and the air at the spot where you're standing.
The beauty of Eddy Covariance is that it continuously collects data, even when nobody is standing there. This lets scientists track how much gas is coming in and out of different fields over time, which helps them understand the role of fields in keeping the environment healthy.
