Tethersonde Mixed Layer Depth

Time series of mixed layer depth estimates from tethersonde profiles.
Profiles of potential temperature, relative humidity, and windspeed have been inspected individually and the best estimate of mixed-layer (ML) depth made. Note this is the depth of a truly well mixed layer (constant potential temperature) not the total boundary layer depth.

Where ML depth = 0, the temperature profile shows a surface-based inversion, i.e. is stably stratified throughout the whole lower atmosphere. This is a very common case.

Aerosol can be expected to be well mixed throughout the ML, but probably not above.

Files are provided in matlab and ascii format, along with a figure with ML depths overploted on tethersonde time-height series.
