Iquique GAUS Radiosonde Data (EOL Format)



This dataset contains data from the NCAR GPS Advanced Upper-Air Sounding System (GAUS) station located at Iquique, Chile for the VAMOS Ocean-Cloud Atmosphere-Land Study (VOCALS) campaign. The variables pressure, temperature, and relative humidity are calibrated values from measurements made by the radiosonde. The dew point is calculated from the relative humidity and temperature. The geopotential altitude is calculated from the hydrostatic equation using pressure, temperature, and relative humidity. The rate of ascent is calculated from pressure. The radiosonde position (lat, lon, GPSAlt) and winds are measured by use of a GPS receiver in the sonde.

NOTE: The VOCALS radiosonde data sets were re-released on June 24, 2009. A correction was made to remove a .4 mb offset incorrectly applied to the pressure data during post-processing.
