sea level correction at atmospheric correction

Good day,

Q1: Whether correctly I understand, what the difference between sea level and height above a sea level lake is considered in current version of standard atmospheric correction procedure?

Q2: is it right for all lakes?
For example, Caspian Sea  height is lower of sea level, but Baikal and Teletskoye Lakes height are higher  of sea level.

Q3: If Q1 and Q2 are right, the next question is about different scanner and level2 format. Is sea level correction procedure done now for SeaWiFS (GAC and MLAC) and MODIS-Aqua/Terra during their all lifetime?

My English is not well, but I think you understand me.
Some years ago i asked you about it. If i remember right then after 2008 you turn on automatic the sea level correction in standard atmospheric correction. (?!)

Thank You,

Yes, the height of the water body is accounted for in our data processing.  An adjustment to the Rayleigh correction is made based on the lake surface height relative to mean sea level.  Yes, ALL mission we support are so corrected.
