Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 09:13 PM | Dataset Last Updated: September 01, 2004 at 12:00 AM

**Please note, this dataset has been superseded by a newer version (see below). Users should not use this version except in rare cases (e.g., when reproducing previous studies that used this version).**Integrated Global Radiosonde Archive is a digital data set archived at the National Centers for Environmental Information (NCEI). The Integrated Global Radiosonde Archive (IGRA) consists of radiosonde and pilot balloon observations at over 1500 globally distributed stations. Observations are available for standard, surface, tropopause and significant levels. Variables include: Pressure, Temperature, Geopotential Height, Dewpoint, Depression, Wind Direction, and Wind Speed. The period of record varies from station to station, with many extending from 1905 to 2016. Station records for version 1 are available by contacting NCEI Customer Support. IGRA data originate from 11 different sources and have passed through a set of rigorous quality assurance procedures.
