What is the quality of the MISR data products?

Intensive assessment of MISR product data quality is an ongoing activity. Focused studies of some parameters are completed. Quality designators indicate the maturity of products and individual parameters. A product may contain parameters at varying quality levels. Below are the Maturity Level definitions:

Beta: Early release products for users to gain familiarity with data formats and parameters.
Provisional: Limited comparisons with independent sources have been made and obvious artifacts fixed.
Validated Stage 1: Uncertainties are estimated from independent measurements at selected locations and times.
Validated Stage 2: Uncertainties are estimated from more widely distributed independent measurements.
Validated Stage 3: Uncertainties are estimated from independent measurements representing global conditions.

  Calibration Co-registration

The current MISR Quality Statements and new MISR Quality Statements provide quality designators for the individual data products. Also, validation information is available from the MISR web site.
