The International H2O Project (IHOP_2002) was a field experiment that took place over the Southern Great Plains 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.
IHOP_2002 ground-based instrumentation were deployed at multiple locations with both fixed and mobile platforms:
IHOP_2002 operations included a total of six research aircraft that included an unprecedented set of airborne instrumentation. All airplanes were deployed from the Will Rogers World Airport in Oklahoma City, OK.
IHOP_2002 operations were coordinated from the Norman Operations Center located in a trailer next to the NOAA/National Severe Storms Lab facilities on the North Campus of the University of Oklahoma. Several types of models and nowcasting systems were tested in real time.
More complete information on all of the instrumentation that participated in IHOP_2002 can be found in the IHOP_2002 Operations Plan .
