Summary
ABSTRACT: Global Upper Air CARDS Synoptic Sort is digital data set DSI-6306, archived at the National Climatic
Data Center (NCDC). It is meteorological upper air data. CARDS stands for Comprehensive Aerological Data Set.
he goal of the CARDS project has been to produce global upper air data sets based on daily (up to four per day)
radiosonde observations ... suitable for use in evaluating climate models and detecting tropospheric and stratospheric
climate change. A major task of the CARDS project, which began in 1991, has been to build observational databases
and make this data available to the research community and to NCDC customers. Data from over 27 sources has been
collected, converted to a like format, and processed through the Comprehensive Hydrostatic Quality Control (CHQC).
This data was then merged, based upon add/replace algorithms that took into consideration the number of mandatory
and significant pressure levels and the number of errors detected during the CHQC, selecting the best observations
from the available data sets. The data has then been further quality controlled via an advanced Complex Quality
Control (CQC) system. The CARDS database contains some 27 million observations beginning in 1948, comprising a data
set of approximately 64GB. A metadata record for each observation contains information related to the number of
levels in total and by type, as well as a summary of the observation. A full suite of inventories and reports is
available based upon the metadata. Building of future CARDS data sets will be based upon the detection and identification
or removal of systematic errors (biases). Also, CARDS will provide an in-depth upper air station history for 2400+
stations. CARDS data includes the following purely meteorological parameters: clouds and obscuration, pressure,
geopotential height, temperature, relative humidity, dew point depression, and wind speed and direction. CARDS
data also includes a large number of technical specifications and quality control parameters. DSI-6306 is a quality
controlled compilation of many upper air data sets. DSI-6306 is in synoptic order. The following is a partial list of
the data sets that were used in the construction of DSI-6306. (These data sets should not be used separately; they
contain original data as it was received at NCDC, prior to NCDC quality control.) DSI-Number Name FGDC Number DSI-6308

and where observations were taken. For example, DSI-6324 is Brazilian data received from Brazil; DSI-6314 USSR GTS
Global Upper Air was received from the old USSR, who received it over GTS, and it is global data. NCDC maintains this
data set in archive but no longer updates nor actively distributes it. It has been superseded by the Integrated Global
Radiosonde Archive (IGRA) (C00616).
PURPOSE: To make a wide range of climatic data available to researchers and the public.
