[ Update this Record ]

Summary
Abstract: Integrated Global Radiosonde Archive is a digital data set archived at the National Climatic Data Center (NCDC). 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 Wind Speed The period of record varies from station to station, with many extending from 1970 to present. Station records are updated daily and are available online at no charge. IGRA data originate from 11 different sources and have passed through a set of rigorous quality assurance procedures.

Purpose: To make a wide range of climatic data available to researchers and the public.

Quality ATTRIBUTE ACCURACY REPORT: The IGRA quality assurance system consists of a series of specialized algorithms that are applied successively. The procedures can be grouped into seven general categories: fundamental "sanity" checks, checks on the plausibility and temporal consistency of surface elevation, internal consistency checks, checks for the repetition of values, climatologically- based checks, ...
