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. To make a wide range of climatic data available to researchers and the public. SUPPLEMENTAL INFORMATION: data set CURRENTNESS REFERENCE: Ground Condition

Attribute_Accuracy_Report:
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, checks on the vertical and temporal consistency of temperature, and data completeness checks (Durre et al. 2006). Each successive check makes a binary decision on the quality of a value, level, or sounding; either the data item passes the check and remains available, or it is identified as erroneous and thus set to missing. Although all variables are quality-assured, temperature, pressure, and geopotential height receive somewhat greater scrutiny than the other variables. LOGICAL CONSISTENCY REPORT: Unknown COMPLETENESS REPORT: The following data problems have come to our attention and will be addressed during future enhancements of the IGRA quality-control system: a. Geopotential heights prior to 1950 at some Russian stations were expressed in geometric meters rather than geopotential meters in the relevant source dataset Global Upper Air CARDS DSI-6310 (C00553). b. At certain stations during certain months, wind speed may be incorrectly reported in knots or in hundredths of meters per second. c. The level indicators identifying tropopause levels should be used with caution since these identifications have not been quality-controlled, but occasionally have suspicious characteristics. For example, there are cases in which levels in the lower troposphere or middle to upper stratosphere are identified as tropopause levels. For the most up-to-date information on the status of the dataset, see the status report at www1.ncdc.noaa.gov/pub/data/igra/status.txt.
