CASES-97 project description

Cooperative Atmospheric Surface Exchange Study 1997

Summary

Observing and Modeling the effects of soil moisture on the diurnal behavoir of the Atmospheric Boundary Layer.

Objectives:

The broad objectives were two-fold: a) observe and model the effects of the fair weather boundary layer's diurnal cycle, and b) begin a determination of the relationship between S-band polarized radar signals, NEXRAD radar signals, and observed rainfall. Specific CASES-97 objectives include: characterizing the PBL diurnal cycle; computing budgets of PBL heat and moisture; providing a dataset for use in models; evaluating ABLE instrumentation; testing techniques for examining mesoscale eddies; field testing new bistatic radar; roll-vortex investigations; improving WSR-88 rainfall estimation; evaluating dual-polarization rainfall estimation; determining length scales for soil moisture content.
