The International H2O Project (IHOP_2002) was designed to sample the three-dimensional time-varying moisture field to better understand convective processes. Numerous research and operational water vapor measuring systems and retrievals were operated in the U.S. Southern Great Plains in the summer of 2002. This was done in combination with more traditional observations of wind and temperature. Boundary-layer evolution studies were designed to maximize observational overlap from multiple instruments to better understand the moisture distribution during the evolution of the daytime convective boundary layer. This talk will show detailed observations from before sunrise through the development of the convective boundary layer on 14 June 2002. The combination of data provide a comprehensive description of the development and distribution of the low-level moisture field, in particular, during the early morning hours. In addition, the data also provide an interesting insight into the structure of the moisture field as the boundary layer organization evolved from horizontal convective rolls into open-celled convection.
