AB: A tethersonde system was deployed at Fort Cobb, Oklahoma during the Cloud and Land Surface Interaction Campaign (CLASIC) June 8-24 2007 with the objective of characterizing the diurnal cycle of lower boundary layer structure up to 500 m including wind, pressure, temperature, humidity as well as CO2 profiles over harvested wheat. One unique feature of this data set is that includes fair weather, pre-storm and post-storm conditions for a record monthly rainfall in Oklahoma, in excess of 300 mm at the site. Here, we discuss specifically the diurnal cycle of (potential temperature) and q (specific humidity) and overall boundary layer structure during the duration of the field campaign with an emphasis on conditions before and after one major rain event. Preliminary regional estimates of surface roughness and friction velocity, and sensible heat flux and latent heat flux are also presented.
