CPOL Research Radar

Overview

CPOL is a dual-polarisation C-band radar that have been producing data since 1998. It has been referenced by a 100+ publications and it is actively used by a large community in Australia and around the world. CPOL is unique, as it is the only dual-polarisation radar in the Tropics. It has been used by NASA to calibrate the satellite TRMM.

The Australian Bureau of Meteorology has developed a new processing with a new quality control (that has led to scientific publications) for the CPOL dataset.

This subcollection is separated into a number of products that relate to the level of processing applied. Please refer to the associated records linked below for more information about each product.

Datasets

Level 1b

Corrected and calibrated data that includes volumetric retrievals

NCI THREDDS Data Server

  • PPI: Radar volumes that include reflectivity, corrected and calibrated reflectivity, rain rate, Doppler Velocity (when provided), corrected Doppler velocity and azimuthal shear. This data uses the CfRadial data model for the netCDF data format.

  • GRID: Radar volumes gridded onto an equidistant azimuth projection at a 1000 m horizontal resolution (70 km range) and 2500 m resolution (150 km range) at 500 m vertical resolution to 20 km altitude. This dataset includes corrected and calibrated reflectivity, rain rate and azimuthal shear. This dataset uses the netCDF data format.

Level 2

Daily grids

NCI THREDDS Data Server

  • Daily grids for radar sites that include rain rate (at radar altitude), corrected and calibrated reflectivity (2500 m above radar altitude), azimuthal shear (2500 m above radar altitude). This dataset uses the netCDF data format.
