New Data Loggers Deployed

As shown in this partial screen capture, the Real Time Monitoring and Control feature displays data that allows local observers to quickly check the status of the instrument system.

As part of ongoing effort to upgrade data loggers and logging systems throughout the ARM Climate Research Facility, new Campbell Loggers (version CR23X) are being installed at the Tropical Western Pacific (TWP) and at the North Slope of Alaska (NSA) locales. In fall 2003, Campbell Loggers for the surface meteorology systems at NSA were installed. In June 2004, Campbell Loggers were installed for the surface meteorology (SMET), sky radiation (SKYRAD) and ground radiation (GRNDRAD) systems at the TWP Darwin site. Next in line for logger upgrades are the TWP sites of Manus and Nauru, and the SKYRAD and GNDRAD systems at NSA’s Barrow and Atqasuk sites.

The new data loggers, developed by Campbell Scientific, Inc., replace the existing PC-based data collection systems and the ZENO® 3200 Dataloggers from Coastal Environmental Systems, Inc. Data from each of the Campbell Loggers is collected by one main on-site computer using Campbell Scientific’s LoggerNet software. Using Real Time Monitoring and Control (a feature of the LoggerNet software), displays are generated that provide an instantaneous readout of the data, allowing local observers and technicians to make sure the instruments and sensors are working as they should. In addition, remote administration (RAdmin) software is loaded onto each main computer. This lets remote users log on to the computer to view what is happening and, if needed, download files or modify the computer, display, loggers, etc., as if they were sitting in front of it. This capability greatly enhances the speed with which repairs and troubleshooting can be performed.
