version 3.0.0

TITAN - Automatic data quality control software

Main changes with respect to version 2.1.0:

• The tests are based on titanlib
• The main program is now modular
• Tests and example datasets are provided
• Tests changes:
  • The SCT can make use of a background field
  • Introduction of the First-Guess Test (FGT)
  • Introduction of SCT dual for dichotomous (yes/no) variables. SCT dual can make use of a background field.
  • STEVE and COOL tests have been removed. Use SCT dual instead.
• Input/Output:
  • output file do not include SCT-score and coefficients of representativeness
  • background fields, it is possible to specify more than two background fields

version 2.1.1

TITAN - Automatic data quality control software

changes with respect to version 2.1.0:

• read netcdf file with land-area fraction, manage the case of missing PROJ4 string

version 2.1.0

TITAN - Automatic data quality control software

changes with respect to version 2.0.1:

• first-guess check, it is now possible to specify range of observed and/or first-guess values
• buddy checks, now the first-guess field can be used also in those checks
• included "break" options to stop tests if few observations are flagged
• fixed some bugs

version 2.0.1

TITAN - Automatic data quality control software

changes with respect to version 2.0.0:

• fixed bug while writing the provider identifier on the output file

version 2.0.0

TITAN - Automatic data quality control software

• variables: temperature, precipitation, relative humidity, surface snow thickness
• several checks available: plausibility, buddy checks, cross-checks between variables, spatial consistency test (SCT), check against first-guesses
• adjust precipitation for wind-induced under-catch
• radar-derived precipitation can be returned within the output file

Notable changes with respect to version 1.0.0

• COOL test replaces STEVE and puddle- checks
• SCT smart-box approach implemented
• SCT station-by-station approach implemented
• input/output, is now possible to remove duplicates from the input data
• bug fixes and performance improvements

version 1.0.0

• variables: temperature, precipitation, relative humidity, surface snow thickness
• use a configuration file (optional)
• two additional checks: buddy-check (based on the definition of an "event"); puddle-check
• radar-derived precipitation can be returned within the output file
• bug fixes and performance improvements

version 1.0.0-beta

Change-log:

• possibility to check observations of: temperature, precipitation, relative humidity
• added checks against a user-specified first-guess field (deterministic and/or ensemble of fields)
• possibility to use an external first-guess field in the SCT and improvements in the estimation of SCT parameters
• added isolated event test (STEVE)
• new routine to read netCDF files that support ensemble of model fields. Special support for reading MEPS files and radar-derived precipitation as stored in the MET Norway archive (hourly accumulated precipitation).
• improved debug options
• bug fixes in the plausibility check, SCT

version 0.1.1

Change-log:

• bug fixed in the plausibility test
