Pseudovertical temperature profiles give insight into winter evolution of the atmospheric boundary layer over the McMurdo dry valleys of Antarctica
Measuring routine vertical profiles of atmospheric temperature is critical in understanding stability and the dynamics of the boundary layer. Routine monitoring in remote areas such as the McMurdo Dry Valleys (MDV) of Antarctica is logistically difficult and expensive. Pseudovertical profiles that w...
