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.
