Validation Status Definitions

The TES L2 nadir products have undergone extensive quality control and validation testing. The table below shows the definitions of data maturity developed by the Terra-MISR (Multi-angle Imaging SpectroRadiometer) team and adopted by the TES team.

Term Definition
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 -- note that TES L2 retrievals include fully characterized error estimates
Validated Stage 2 Uncertainties are estimated from more widely distributed independent measurements
Validated Stage 3 Uncertainties are estimated from independent measurements representing global conditions
