From page 10...
... The proposed effort to gather all relevant water vapor data sets should include careful attention to incorporating metadata so that updated versions of data sets can be properly identified and linked to previous versions. Other documentation, such as error estimates, also will be critical to future reprocessing efforts.

From page 11...
... Upper level water vapor feedbacks are a major source of uncertainty in global warming simulations. The proposed GVaP focus on global upper tropospheric water vapor could yield especially large benefits in addressing this issue, given the known strengths and weaknesses of the principal data sets to be -assimilated.

From page 12...
... It is especially important for GVaP to engage those responsible for maintaining operational, global climate observing capabilities so that the advances of GVaP can extend beyond its proposed lifetime. GVaP should also involve those responsible for developing new measurement capabilities by documenting and prioritizing deficiencies in current data bases so that performance characteristics of new observing systems (including sampling strategies and optimal mixes of measurements and models)
