of orbits for each validation site at various separation distances.

7.3 Exchange Protocol for preliminary
CALIPSO data
Protocol
For Making CALIPSO Coincident Measurements
- Correlative measurements should
be acquired as close as possible in time and location to the CALIPSO ground
track.
- Correlative measurements should be located as close as possible
in space and time to the CALIPSO overpass. Intercomparisons should include
an assessment of spatial and temporal matching errors.
- Correlative measurements should be of comparable or superior
accuracy and resolution to the CALIPSO measurements.
- The primary CALIPSO validation
period begins approximately 45 days after launch and ends about 18 months
after launch. All CALIPSO data is considered preliminary until it is released
to the public.
Protocol For The Exchange Of Information
And Data
- The CALIPSO QPQ validation team will consist of correlative
measurement investigators that actively participate in the acquisition and
interpretation of observations for validation studies.
- The CALIPSO QPQ validation implementation team will consist
of those responsible for developing and implementing the QPQ validation
program
- Members of the CALIPSO science and QPQ validation
implementation teams will have access to the QPQ correlative measurement
database. These data will not be made available to persons outside of
these teams during the validation period without the expressed approval of
the QPQ Principal Investigator (PI) for the correlative data set.
Likewise, CALIPSO data shall not be provided to persons other than those
scientists that have supplied coincident data without the expressed
approval of the CALIPSO PI.
- QPQ validation network PIs will have access to data
products from the CALIPSO mission that are coincident with the validation
data that have been made available for comparison. The CALIPSO data will
be distributed in segments of a half-orbit or less that overlap with the
QPQ site.
- Predictions of overpass times for all QPQ validation
network sites will be updated on the QPQ validation website (http://calipsovalidation.hamptonu.edu/)
once per week. The status of the CALIPSO satellite will also be available
at this site.
- Members of the QPQ validation team should submit a
"Request For CALIPSO Data" to the Atmospheric Sciences Data
Center at http://eosweb.larc.nasa.gov/
and the appropriate coincident CALIPSO data products will be forwarded to
the requestor.
- Members of the QPQ
validation team without a data archive that is readily accessible to the
CALIPSO science and validation implementation teams, should upload their
data to Hampton University's QPQ data archive. These data should conform
to the common data format specified by the QPQ validation coordinator.
Data products submitted to this server can be updated by the QPQ
validation team member as often as needed. The data will be considered as
“Preliminary” until the CALIPSO team is notified that they are ready for
public distribution.
- QPQ correlative measurement
data set will be archived at a public facility following the validation
phase of the mission. Data submitted to this public archive is voluntary.
Protocol For Publishing CALIPSO
Data Comparisons
- The criteria for publication shall be the ability to make
a definitive statement on the quality of the CALIPSO data products based
upon comparisons between the QPQ validation network and CALIPSO data.
- Manuscripts that include observations
from the QPQ validation network and CALIPSO for publication in peer-reviewed
journals and conference proceedings shall include, as authors, scientists
involved in the preparation of the measurements and their interpretation.
The manuscript must be circulated to all co-authors for review and approval.
PIs/Co-Is responsible for generating a measurement or a data product from
a QPQ validation site shall be offered the right of co-authorship.
- Presentations of these data
and findings in public meetings may be made subject to the approval of the
coauthors.
- Publication of preliminary
CALIPSO data products requires co-authorship with a CALIPSO Science Team
member and approval of the CALIPSO PI and Co-PIs.
