The observers transmit the data to the local NWS office via telephone using a PC based system called PC-ROSA, or telephone the information in via a voice system. Training consists of on site, hands-on instruction with the designated cooperative observer and their backup. An NWS employee usually provides training on the same day of the equipment installation. The training takes about one hour to complete. If necessary, the NWS coop representative provides additional training upon request.
Advanced training includes discussions on basic equipment maintenance.
