Specific Goals of IMPROVE
To obtain comprehensive, quantitative measurements of cloud microphysical variables
in a variety of precipitation systems that are relatively simple in structure,
predictable, and which produce a spectrum of cloud and precipitation hydrometeor
types and interactions.
To obtain corresponding dynamic and thermodynamic measurements (3-D wind,
temperature, and humidity) within and around these precipitation systems,
providing the meteorological context in which the microphysical processes
and precipitation events occurred.
To perform simulations of the observed cases with a mesoscale model (MM5)
that includes a state-of-the-art bulk microphysical parameterizations (BMP),
making use of all available observations in conjunction with advanced data
assimilation techniques to maximize the accuracy of the simulations.
To use the various cloud microphysical data obtained in the field to evaluate
the concentrations and size distributions of all the model-simulated hydrometeor
variables.
Based on these findings, to perform tests of model sensitivity to parameters
and assumptions in the BMP.
To make cost effective and generally applicable improvements in the BMP
that should improve quantitative precipitation forecasting in mesoscale
models.
