Abstract:
Integrated Global Radiosonde Archive is a digital data set archived at the National Climatic Data Center (NCDC). This dataset contains monthly means of geopotential height, temperature, zonal wind, and meridional wind derived from the Integrated Global Radiosonde Archive (IGRA, DSI-6351). IGRA consists of radiosonde and pilot balloon observations at over 1500 globally distributed stations, and monthly means are available for the surface and mandatory levels at many of these stations. The period of record varies from station to station, with many extending from 1970 to present. Monthly means are computed separately for the nominal times of 0000 and 1200 UTC, considering data within two hours of each nominal time. A mean is provided, along with the number of values used to calculate it, whenever there are at least 10 values for a particular station, month, nominal time, and level. The monthly-mean files are updated on the fifth day of each month and are available online at no charge. To make a wide range of climatic data available to researchers and the public.

Attribute_Accuracy_Report:
ATTRIBUTE ACCURACY REPORT: Quality control procedures have been applied to the individual soundings from which the monthly means were computed. No additional quality control has been applied to the monthly means. 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 in the individual soundings might also be reflected in the monthly means and will be addressed at the time of future enhancements of IGRA: a. Geopotential heights prior to 1950 at some Russian stations were expressed in geometric meters rather than geopotential meters in the relevant source dataset (DSI-6310). b. At certain stations during certain months, wind speed may be incorrectly reported in knots or in hundredths of meters per second. 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.
