L0 | Binary CCSDS packets (as produced by the corresponding instrument; unpacked metadata | Within Survey: Within 30 minutes of telemetry arriving at the SOC. | |||||
L1A | Extracted telemetry items; no calibrations or corrections applied; B and Vsc to all investigations | 1. L1A based on Survey data (for SITL support): within 60 minutes of Survey telemetry arriving at the SOC. 2. For burst data, | |||||
L1B | Extracted telemetry data to which instrument-level provisional calibrations have been applied; simple moments, spectral indices | 1. L1B based on Survey data (for SITL support): within 60 minutes of Survey telemetry arriving at the SOC. 2. For burst data, | |||||
Quicklook QL | Scientific data products that are generated using simplified science processing algorithms, e.g. with provisional calibrations. | 1. QL based on Survey data for SITL support: within 60 minutes of Survey telemetry arriving at the SOC. 2. If there's a Burst-based QL, that will be available within 24 hours of the downlink (and arrival at the SOC) of each complete burst segment. | |||||
L2pre | “Instrument-level” research-grade | prelim L2 | "Instrument-level" research-grade scientific data product, best calibrations to shorter-term delivery date | available to the MMS instrument teams within two weeks of telemetry downlink | . Quality is sufficient for designated intra-instrument L2 products to be processed. | Within two weeks of AFG and DFG telemetry arriving at the SOC. Note that this is an internal MMS product and not expected to be released to the general research community. | |
L2 | “Instrument-level” | L2 | "Instrument-level" research-grade scientific data products, definitive products | Available to instrument teams deliver to SOC within 30 days; available to the general research community within 35 days of telemetry downlink | <ac:structured-macro ac:name="unmigrated-wiki-markup" ac:schema-version="1" ac:macro-id="7210ef49-6cdc-4d5c-aeac-30e3489fc555"><ac:plain-text-body><![CDATA[ | L3 | . To support this timeline, instrument teams deliver L2 files to the SOC within 30 days of L0 data being available at the SOC. |
L3 | “Spacecraft- and Mission-level” "Spacecraft- and Mission-level" [research-grade] products; resampled spatially and/or temporally and combined with measurements from other MMS instruments to produce a merged data set. A subset of the ALL "mission-level" L3 products are provided only for designated events (i.e., the mission | available to the general research community within 60 days of the event being identified? Barry Maul will send suggested wording. | success events aka Sweet Sixteen). | 1) Following the point in time when the PI or his designate identifies an event as one on which the instrument teams should focus, the associated Level-3 data from all sources will be made available to the broader scientific communities at the time the PI or his designate validates the scientific value of that data, or within 60 days, whichever period is shorter. |
Note: Survey-based Quicklook and Level-1 products are planned to be used for SITL analysis. FPI is planning to produce a SITL-specific product
