Quality Controlled Version 3b Upper-Air Data
from the SCSMEX/GAME domain
for May and June 1998

Our processing and QC procedure include the following stages:

  1. Get the raw data into a common ASCII format.

  2. Run data through a series of automated internal consistency checks (e.g., gross limit and vertical consistency checks). Criteria for assigning QC flags, based on these checks, are listed here.

  3. Each sounding was visually inspected up to 100 mb using skew-T plots for the thermodynamic variables and vertical profiles for the u and v-wind components. At this stage, suspect data were compared to adjacent sounding times. Questionable (that is, suspicious looking) and bad (physically unreasonable) data values were flagged accordingly.

    Additional details of our qc procedure, are given here .

    Convention adopted for the QC flags on the SCSMEX sounding data.

    Flag Value Meaning
    1 parameter good
    2 parameter questionable
    3 parameter "visually" questionable
    4 parameter bad
    5 parameter "visually" bad
    6 parameter interpolated
    7 parameter estimated
    8 parameter unchecked
    9 parameter missing

    This convection of quality control flags and automated internal consistency checks is patterned after Loehrer et al. (BAMS, 1996) and their QC effort of the TOGA COARE sounding data.

    The following map shows the upper-air sounding sites in SCSMEX/GAME domain for the May and June 1998 period. In all, there are 162 sounding sites with 23,042 sounding available during this period. Your browser will display site name, WMO number and number of available soundings at this site. To determine if quality controlled (QC) upper-air data is currently available for a given site, simply place cursur over site location. Your browser will display site information (site name, WMO number and number of available soundings). To access the ASCII formatted data for this site, simply click left mouse button and save the data file to your home machine.
