Discuss the steps necessary to convert a TIR brightness temperature, measured at the top atmosphere, to the physical temperature of the Earth's surface.

Solutions

Expert Solution

The first step is the proper geolocation. ie. to determine the proper location where the TIR brightness temperature is being measured, ,This geolocation data is also used to calculate how much energy is being receivied by the area. Then we use the Planck's Law to estimate how the spectrum will be for a particular surface at temperature T, this is then corrected to include errors due to the sensor profile used for detecting the TIR Brightness temperature. Once the errors are removed, then we calculate the temperature of the surface by substituting the spectrum we got using the satellites, which then helps us to find the actual surface temperature of the Earth surface at that particular location.

In the figure, the top tank, which is open to the atmosphere, contains water and the bottom tank contains oil covered by a piston. The tank on the right has a freely movable partition that keeps the oil and water separate. The partition is a vertical distance 0.10 m below the open surface of the water. If the piston in the bottom tank is 0.50 m below the open surface of the water and has a surface area of 8.3...
