The researchers studied how heat moves from the ground into the air using a special tool called a Large Aperture Scintillometer. They looked at factors like soil moisture, temperature, and wind speed to see how they affect heat transfer. They found that on sunny days, more heat goes into the air compared to cloudy days. Wet soil reduces heat transfer, while warm soil increases it. Wind speed doesn't have a big impact. Different methods of measuring heat transfer gave similar results. This research helps us understand how heat moves between the ground and the air, which is important for predicting weather and climate patterns.
