Abstract:

Data on precipitation parameters are critically needed for global-scale climate monitoring.
The major source of data will be estimates of rainfall amount derived from geostationary
satellite observations. Since these are indirect measurements, validation through
ground-based measurements is required. This project concerns development of an instrument
for in-situ measurements of instantaneous droplet size distributions and rain rates
using optical scintillations. The instrument will be compact and permit unattended
weather observations.
In Phase I, the firm will conduct a theoretical and empirical study to obtain the
optimum design parameters for a prototype sensor. The design will address the important
engineering and operational issues and will contain sufficient detail to make an
assessment of the resources required for Phase II development.

Potential Commercial Application:

Potential Commercial Applications:  A compact instrument for unattended field operation
could have domestic and international commercial applications for obtaining rain
data.
