Overview:

The Midlatitude Continental Convective Cloud Experiment (MC3E) was a collaborative effort 
between the NASA Global Precipitation Measurement (GPM) mission Ground Validation (GV) 
program and the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) 
Climate Research Facility. Conducted in the spring of 2011, MC3E was centered in 
north-central Oklahoma, USA. The overarching goal of the field campaign was to collect a 
comprehensive set of observations describing precipitation microphysics over continents 
during the warm season. The observations will be used to refine GPM retrieval algorithms 
over land. At the same time, DOE objectives focused on relating the cloud microphysical 
observations to accompanying observations of cloud kinematics and the surrounding environment. 
These observations will be used to improve the understanding and representation of cloud and 
precipitation microphysical interactions within cloud-resolving models.
