Atacama Large Millimeter Array

Radiosonde Data

To determine the vertical atmospheric profiles, ESO in collaboration with NRAO, Cornell University, Smithsonian Astrophysical Observatory, and Nobeyama Radio Observatory have launched several radiosondes. These data can be access through the NRAO ALMA site studies homepage .

The radiosonde equipment was manufactured by A.I.R., Inc. a company now own by Vaisala Inc. Contacted by phone, after the merging, they guaranteed that they will continue producing the radiosonde sensors that we are using.
