Other: ARM TWP Radiosonde Data Set


This data set contains the 12-hour Radiosonde observations from the Coordinated Energy and Water Cycle Observation Project (CEOP) Global Energy and Water Cycle Experiment (GEWEX) Americas Prediction Project (GAPP) Program at its Tropical Western Pacific (TWP) facility in Darwin, Manus Island and Nauru. This data set includes 2-sec vertical resolution observations of temperature, pressure, dew point, wind speed, wind direction, and relative humidity. This data set covers the time period from 1 October 2002 through 31 December 2009. Further information about the ARM TWP site is available at . These data are are in monthly zip files (10-20 Mb each) containing netcdf files. These data have not been processed or quality controlled by NCAR/EOL.
