Sound intensity level in air is expressed on a logarithmic scale with reference to a sound intensity of 1e-12 W m-2. LI = 10 log10(I/I0) where LI is sound intensity level, I is sound intensity and I0 is the reference sound intensity.</description> 2049 2049 </entry> 2050 2050 <entry id="sound_intensity_level_in_water"> 2051 <canonical_units> dB</canonical_units>2051 <canonical_units>1</canonical_units> 2052 2052 <description>Sound intensity is the sound energy per unit time per unit area. Sound intensity level in water is expressed on a logarithmic scale with reference to a sound intensity of 6.7e-19 W m-2.

Sound pressure level in air is expressed on a logarithmic scale with reference to a sound pressure of 2e-5 Pa. Lp = 20 log10(p/p0) where Lp is the sound pressure level, p is the rms sound pressure and p0 is the reference sound pressure.</description> 2065 2065 </entry> 2066 2066 <entry id="sound_pressure_level_in_water"> 2067 <canonical_units> dB</canonical_units>2067 <canonical_units>1</canonical_units> 2068 2068 <description>Sound pressure is the difference from the local ambient pressure caused by a sound wave at a particular location and time. Sound pressure level in water is expressed on a logarithmic scale with reference to a sound pressure of 1e-6 Pa. Lp = 20 log10(p/p0) where Lp is the sound pressure level, p is the rms sound pressure and p0 is the reference sound pressure.</description> 2069 2069 </entry> … … 2866 2866 <description>The specification of a physical process by the phrase due_to_process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "tendency_of_X" means derivative of X with respect to time. "Content" indicates a quantity per unit area. "Layer" means any layer with upper and lower boundaries that have constant values in some vertical coordinate. There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be model_level_number, but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well.</description> 2867 2867 </entry> 2868 <entry id="tendency_of_water_vapor_content_of_atmosphere_layer_due_to_turbulence">2869 <canonical_units>kg m-2 s-1</canonical_units>2870 <description>The specification of a physical process by the phrase due_to_process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase.
