A meteorological measurement campaign was held during March 2005 over the Venezuelan llanos using pilot balloon and radiosonde observations. The objectives of these measurements were to: 1) determine the diurnal variation of the low level jet that has been observed in pilot balloon data during the last 3 years at San Fernando de Apure, 2) determine the structure of the LLJ from a network of 7 pilot balloon sites, 3) validate the structure of the LLJ that has been shown from the recently available regional analyses, 4) strengthen the interest in meteorological measurements in Venezuela as part of the educational component of PACS-SONET.
