High Resolution Research Soundings from Algonquin

This site was operated by the Atmospheric Technology Division(ATD). Soundings were typically taken either four times a day or eight times a day during IOPs,i.e. every three or six hours beginning with 00 UTC.

This dataset underwent JOSS automatic quality control procedures. Since the soundings are loaded into the database by actual release times and the actual hour of release is typically one hour before the nominal time, when attempting to preview a sounding try the hour right before the nominal time first. For example: for an 18 UTC sounding, try using hour 17.
