Seminar Title: Climate modeling meets remote sensing: How do you measure a storm cloud?
Speaker: Scott Collis, Remote sensing engineer, ARM Climate Research Facility (ACRF)
Date/Time: 2010-08-11 15:00
Location: Bldg 240 Conference Center 1404-1405
Description:
The rapid move towards the regionalization of climate models leads to the
question: How valid is the atmosphere being parameterized within the model
at regional scales? Given the massive disparity in spatial scales between
dependable in-situ measurements and a global model grid cell how do you
verify that atmospheric processes are being represented accurately? Recent
publications detail the use of sounding data to drive a variety of climate
and cloud resolving models for intercomparison but these results need to be
underpinned by measurements. This talk will introduce the use of Doppler
radar in the remote sensing of precipitating cloud systems and the
application of variational techniques to generate model-like data from the
measurements they produce for the verification of modeling efforts.
