Incorrect Terra IR Water Vapor Profiles from Band 27 Crosstalk

Description: April 2016 update from PGE03 developers: A band 27 cross-talk problem, that increased (and became more pronounced) over time starting around 2010, produced incorrect IR Water Vapor profiles, with artificially low moisture content in the middle atmospheric layer and excessively high values in the upper troposphere. The MCST is still investigating possible fixes for this problem. Users should note that the IR Water Vapor profile data is in an SDS called "Water_Vapor", "Water_Vapor_Low", and "Water_Vapor_High" in the 07_L2 file.
