MADIS Snow Quality Control

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

Automated Quality Control

Level 1 QC checks are considered the least sophisticated, level 2 the most sophisticated checks. The following table lists the snow variables* that are QC'ed, and click here for the checks that are used:
