Notes Concerning Data Quality:

PAMZ data includes:

  1. Data that has been subjected to rigorous quality assurance and quality control (QA/QC) processes. Data collected prior to the beginning of last month will normally have undergone QA/QC processing.
  2. Raw data that must undergo QA/QC processes before it can be considered valid. The most recent data available on the PAMZ site is raw data.

Most raw data differs only slightly from data that has undergone QA/QC processing. Significant differences are rare.

PAMZ continuous and passive data is also available through the CASA Data Warehouse.

The PAMZ website maintains continuous data for two years and passive data for one year. Older data can be accessed through the CASA Data Warehouse.
