International H2O Project (IHOP) 2002

Project Location:Southern Great Plains, Oklahoma
Project Dates: 13 May - 25 June 2002

The International H2O Project (IHOP_2002) is a field experiment that took place over the Southern Great Plains (SGP) of the United States from 13 May to 25 June 2002. The chief aim of IHOP_2002 was improved characterization of the four-dimensional (4-D) distribution of water vapor and its application to improving the understanding and prediction of convection. The region was an optimal location due to existing experimental and operational facilities, strong variability in moisture, and active convection.

Monthly Weather Review IHOP ABL Special Issue

The MWR co-chief editors, Dave Jorgensen and Bill Skamarock, have agreed to host a second IHOP Special Issue on ABL processes. Contributions are solicited from all IHOP-related studies of ABL processes, including observational and modeling. Suitable contributions may include boundary layer heterogeneity (BLH), boundary layer evolution (BLE), low-level jet (LLJ) and convection initiation (CI) studies focused on ABL processes and ABL-relevant instrumentation studies. When submitting your manuscript to MWR, please state in your cover letter that it is for the IHOP Special Issue on ABL Processes. The deadline for submission is 1 March 2007.

For more information, please contact Cyrille Flamant ( , Christoph Kiemle ( or Tammy Weckwerth (
