Validation of Aura data: needs and implementation

We describe the needs for validation of the Aura scientific data products
expected in 2004 and for several years thereafter, as well as the implementation
plan to fullfill these needs. Many profiles of stratospheric and tropospheric
composition are expected from the combination of four instruments aboard Aura,
along with column abundances, aerosol and cloud information. The Aura validation
working group and the Aura Project have been developing programs and collaborations
that are expected to lead to a significant number of validation
activities after the Aura launch (in early 2004). Spatial and temporal variability
in the lower stratosphere and troposphere present challenges to validation of Aura
measurements even where cloud contamination effects can be minimized. Data from
ground-based networks, balloons, and other satellites will contribute in a major
way to Aura data validation. In addition, plans are in place to obtain correlative
data for special conditions, such as profiles of O3 and NO2 in polluted areas.
Several aircraft campaigns planned for the 2004-2007 time period will provide
additional tropospheric and lower stratospheric validation opportunities for Aura;
some atmospheric science goals will be addressed by the eventual combination of
these data sets. A team of "Aura liaisons" will assist in the dissemination of
information about various correlative measurements to be expected in the above
timeframe, along with any needed protocols and agreements on data exchange
and file formats. A data center is being established at the Goddard Space Flight
Center to collect and distribute the various data files to be used in the
validation of the Aura data.
