A frequent issue with outdoor microphones is low-frequency wind noise generation. Because of the geometry of outdoor recording equipment, a small pressure difference is created at the grid cap of the microphone due to the microphone's presence. This pressure difference results in possible contamination of outdoor sound level measurements. This effect can be reduced as measurements are taken closer to the ground because of a no-slip boundary condition, which purports that wind speeds will be slower closer to the ground due to the atmospheric boundary layer.
