| qcstg1_2 |
Reads LDAD mesonet observation files in netCDF format, performs stage
1 and 2 QC checks for the AWIPS Quality Control and Monitoring System
(QCMS), (i.e., validity, internal consistency, and temporal
consistency checks); creates QC data descriptors and departure values,
and then writes QCed netCDF and CSV files. Variables to be QCed, QC
checks to be used, and thresholds for the QC checks are specified on
as2 in /awips/fxa/ldad/MSAS/fslparms/qc_work_table.mesonet.
Run on any desired schedule (e.g. every 5 minutes), but right before sfcing to allow the analysis cycle the maximum number of obs. |
| sfcing |
Reads in surface land and buoy data, applies QCMS stage 1 and 2 QC
checks to all data sources (other than the LDAD mesonet files handled
by qcstg1_2), and writes the data and QC results out in MSAS database
format. Three hour altimeter change and MSAS sea-level pressure are
also calculated and QCed with the QCMS stage 1 and 2 checks.
Run after a significant number of hourly surface stations have reported (e.g. 18 minutes past the hour). |
| sfchqc |
Performs horizontal quality control checks (also known as the QCMS
stage 3 spatial consistency check) using optimal interpolation; and
calculates and outputs ASCII summaries of hourly quality control
statistics and observation files (stratified by the subsource numbers
defined in the sfchqcin.dat file located in
/awips/fxa/ldad/MSAS/fslparms). The stats are stored in separate qc1/,
qc2/, etc. subdirectories.
The program also creates the backgrounds
to be used by sfcanl when doing the analyses.
Run after sfcing. |
| sfcanl |
Analyzes nine surface variables:
Run after sfchqc. |
| qcstg3 |
Adds the results of the spatial consistency check to the QCed LDAD mesonet
netCDF observation files, and also creates QCed CSV files that contain the
spatial consistency check results.
Run after sfchqc. |
| sfcver |
Keeps a running track of the mean absolute error and standard
deviation of the MSAS surface analysis as compared to surface and buoy
observations valid at the same time. A set of files contain the
statistics, as well as the top 25 maximum residuals and their station
codes for all analysis variables.
Run after sfcanl. |
| sfcncdf |
Converts MSAS grids from MSAS database format into netCDF format. Pressures are also
converted from hPa to Pa.
Run after sfcanl. |
| sfcnmc |
Reads in model-generated surface and upper-air grids,
interpolates to MSAS grid points, and writes out
the new grids in MSAS database format.
Run after every run of the background forecast model, which is currently the CONUS211 Eta. |
| qcstats |
Creates a daily summary table showing the total number of observations
QCed with each quality control check, and the percentage of
observations failing each check, for all variables processed by the
QCMS. The table is also stratified by the subsource numbers defined in
/awips/fxa/ldad/MSAS/sfchqcin.dat.
Run each day, after the last qcstg1_2 processing for the 23 UTC run. |
| asos |
Computes daily, weekly, and monthly summaries of quality control
statistics for NWS sea-level pressure, potential temperature, surface
wind, and dew point temperature observations.
Run once each day (after the final sfchqc run) for each stratification of QC statistics located in the qc1/, qc2/ etc. subdirectories. |
