MADIS RSAS Quality Control

This page provides a detailed description of the quality control (QC) processing and data structures for the RSAS surface grids. For a general overview of MADIS quality control, click here.

Automated Quality Control

Table 1 lists the QC checks applied to the various surface observations in AWIPS.

Table 1. Quality control checks implemented in AWIPS 
for surface observations input through the LDAD and SBN
communications networks.  The checks consist of internal
consistency (IC), validity (VC), temporal consistency
(TC), and spatial consistency (SC).  

* As of OB4 the hourly QC applied to Altimeter Setting has
  had the SC added to the list of employed checks for LDAD
  mesonet data, and the VC, TC, and SC have been applied
  to the SBN altimeter data as well.
