Doppler Weather Radar Research and Development
ROC Project 13 – Analysis of Weather Radar Observations of Severe Convection to Understand Severe Storm Processes and Improve Warning Decision Support
NEXRAD Technology Transfer
Funding Type: CIMMS Task II
Objectives
Develop, mature, and transition radar applications and algorithms into
the WSR-88 baseline; improve WSR-88D data quality and usefulness.
Accomplishments
During the reporting period, progress was made on several tasks, including:
1) dual polarization – revised QPE and Particle Type Algorithms
were transferred to the ROC, base data and algorithm products were
evaluated, dual-polarization verifications work was performed, and
preparation for the testing of the new WSR-88D prototype was started;
2) velocity dealiasing – two different dealiasing algorithms
were tested on WSR-88D VCP 31 (low PRF) data to try to improve the
quality of the data, and the advantages of each algorithm were documented
and remaining deficiencies were listed; and 3) radar database – a
large number of radar data sets (both baseline and experimental) were
collected, including Level 1 time series data – these data sets
were enhanced by the addition of supplemental data from other sensors
and were added to the extensive archive maintained as a resource for
application development and testing.
This project is ongoing.
