Data Exchange Protocol
Exchange Protocol for preliminary CALIPSO data
Protocol For Making CALIPSO Coincident Measurements
- Correlative measurements should be acquired 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
are considered preliminary until they are 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 people outside of these teams
during the validation period without the expressed approval of the
Principal Investigator (PI) for the correlative data set. Likewise,
CALIPSO data shall not be provided to people other than those scientists
that have supplied coincident data without the expressed approval
of the CALIPSO PI.
- QPQ validation team 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 team 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
. 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 will be archived at a public facility
following the validation phase of the mission. Data submitted to this
public archive are 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 data and CALIPSO data.
- Manuscripts that include observations from the QPQ validation team 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.
