General Overview
Global Positioning System (GPS) receivers and antennas provided by the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) have been deployed at the ARM Climate Research Facility (ACRF) Tropical Western Pacific (TWP) sites at Nauru, Manus Island, and Darwin. The data from these systems are being acquired and processed by the SuomiNet project to provide 30-minute values of precipitable water vapor and other quantities.
The processed data are delivered to the ACRF External Data Center (XDC) in netCDF format and are available from the ARM Data Archive under the Global Earth Coverage (GEC) category in files named gec30suomigpsX1.c1. These files contain data from SuomiNet and other GPS stations located outside the contiguous 48 United States, including Barrow, Alaska. SuomiNet data from within the contiguous 48 States, including 15 stations at selected Southern Great Plains (SGP) extended facilities, are available from the ARM Data Archive in files named sgp30suomigpsX1.c1 beginning June 2001.
