Detailed Description

Profile QC checks.

The temperature consistency checks available are as follows:

Basic checks of pressure
Check for different temperatures at the same pressure
Temperature sign change test using model background
Check for superadiabatic layers more than 50 hPa above surface
Check of standard level temperatures against values interpolated from significant levels
Check for hydrostatic consistency of standard levels (+ surface)
1. calculation of thickness residuals
2. decision making algorithm used where there are large residuals
Junk whole report if > 8 errors There are also consistency checks for the interpolated wind speed and the relative humidity.

The sign, standard level and hydrostatic checks are largely based on methods described in the WMO Guide on the Global Data-Procesing System (1993). In general the tolerances have been relaxed slightly so that fewer 'marginal' cases are flagged. In the hydrostatic check the effect of moisture on the thickness is neglected and no special account is taken of the tropopause. Corrections are suggested for apparently simple temperature or height errors. If a height correction is within 10 m of a multiple of 100 m then the rounded correction is applied, temperature corrections are not applied. In some cases interpolation flags are switched off if the hydrostatic check is fairly clear-cut.

Inputs:

Arrays containing observed and background values
- Should be in order of increasing height/decreasing pressure
- interleaved standard and significant levels (if input is standard levels only then superadiabatic and hydrostatic checks will be performed)

Outputs:

QC flags
Some corrections to reported values (not applied by default):
- corrections to sign of temperature
- corrections to height (multiples of 100 m)

◆ getMismatches()

Return the number of mismatches between values produced by the checking routines and the equivalents produced in the OPS code. The values checked are: the QC flags for each observation, intermediate values used in various calculations for each observation, and error counters for each profile.
