ATom data management plan: Data products and submission requirements Observed data and model products will be submitted in NetCDF or ICARTT format www-air.larc.nasa.gov/missions/etc/ESDS-RFC-019-v1.1_0.pdf Katja Drdla is the ATom data Schematic showing ATom data flows

ATom data management plan: Data products and submission requirements Measured data are expected from launch to landing please apprise if this is not feasible for your instrument Preliminary (Level 1) instrument data will be posted to the Ames archive within 24 hours of landing. posting dependent on internet accessibility in remote locations ICARTT format required (unless NetCDF justified); necessary metadata in header preliminary data used to assess performance and readiness for next flight quick-look merged data products will be generated and posted promptly no 24-hour deadline for WAS, SAGA filters, and perhaps PANTHER GC data – others with no 24-hr products? We must know when available and specify these.

ATom data management plan: Data products and submission requirements Final (Level 2) instrument data posted to the Ames archive within 7 months of the end of each deployment and will be accessible to the public. Relaxed if a final data date conflicts with a subsequent ATom deployment Derived (Level 3 and 4) science products posted to the Ames archive within 9 months of end of each deployment and will be accessible to the public. The Level 3 product is the full chemistry description of air masses sampled on a 500 m (vertical) by 8 km (along track) grid. Level 4 derived products include profiles and joint probability statistics of Tier 1 measured species (Table of the proposal) as a function of altitude, a variety of time- merged products, integrated columns, altitude-vs-latitude (“curtain”) plots, and chemistry-climate model output including observationally constrained production and loss rates for CH 4 and O 3, and aerosol evolution.

ATom data management plan: Data archiving When ATom concludes in 2018, all data products, scientific algorithm software, coefficients, and ancillary data used to generate these products, are required to be posted to the NASA Langley Distributed Active Archive Center (DAAC) All the ATom data sets from the very first deployment will each receive a unique and permanent DOI and will be citeable in publications. At some time after 2018, the ATom data sets will be transferred to the Langley DAAC, but that transfer should be invisible to all of you and the outside users as the unique DOI will be redirected to either ESPO or the DAAC, whomever is holding the data. This transfer will/should include raw instrument data (Level 0) if this can be archived.

ATom data management plan: Data policy PIs can of course share their own measurements with anyone they are collaborating with, but they cannot share any other ATom data outside the team until the public release. PIs and instrument team members responsible for generating an essential measurement or data product must be offered participation as co-author in manuscripts. Upon posting (7 or 9 months post deployment), the final data (including Level 2, 3, and 4 products) are open to public use via the ESPO archive in full compliance with NASA policy.
