WHEN FULLY IMPLEMENTED...THE NOAAPORT AND RPCCDS COMMUNICATIONS
THROUGHPUT OF WSR-88D PRODUCTS WILL DOUBLE. FOR EACH RADAR...
THE AVERAGE HOURLY PRODUCT VOLUME VIA RPCCDS WILL BE 
APPROXIMATELY 5.2 MEGABYTES /MB/ AND THE AVERAGE DAILY VOLUME 
WILL BE 124.2 MB. WHEN FULLY IMPLEMENTED...THE AVERAGE DAILY 
VOLUME FOR ALL 155 WSR-88D RADARS WILL BE 20 GIGABYTES /GB/. 
WORST CASE HOURLY THROUGHPUT IS ESTIMATED TO REACH 19 MB FOR A 
SINGLE RADAR AND 1.5 GB FOR ALL 155 RADARS. ON NOAAPORT... 
PRODUCTS ARE FURTHER COMPRESSED AND THEREFORE THROUGHPUT WILL BE 
REDUCED SOMEWHAT.
