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.
