Quality All MODIS/Terra sea ice products are considered validated at stage two, meaning that product accuracy has been assessed over a widely distributed set of locations and time periods via several ground truth and validation efforts. Quality indicators for MODIS sea ice data can be found in the following two places: * AutomaticQualityFlag and the ScienceQualityFlag metadata objects and their ... corresponding explanations: AutomaticQualityFlagExplanation and ScienceQualityFlagExplanation located in the CoreMetadata.0 global attributes * Custom local attributes associated with each SDS, for example Ice Surface Temperature. No automated quality assessment is done in this algorithm. All QA is inherited from the MOD29 product. These quality indicators are generated during production or in post-production scientific and quality checks of the data product. For more information on local and global attributes, go to one of the following links: * MOD29E1D and MYD29E1D

Local Sea Ice Attributes, Version 5 * MOD29E1D and MYD29E1D Global Sea Ice Attributes, Version 5 The AutomaticQualityFlag is automatically set according to conditions for meeting data criteria in the sea ice algorithm. In most cases, the flag is set to either Passed or Suspect, and in rare instances, it may be set to Failed. Suspect means that a significant percentage of the data were anomalous and that further analysis should be done to determine the source of anomalies. The AutomaticQualityFlagExplanation contains a brief message explaining the reason for the setting of the AutomaticQualityFlag. The ScienceQualityFlag and the ScienceQualityFlagExplanation maybe updated after production, either after an automated QA program is run or after the data product is inspected by a qualified scientist. Content and explanation of this flag are dynamic so it should always be examined if present in the external metadata file. A sampling of products will be inspected. Random sampling or support of specific events, such as field campaigns, may also be conducted. Specific information on the science quality of the sea ice data products is reported in the ScienceQualityFlagExplanation object in the CoreMetadata.0 global attribute. The URL for the QA site is given in the product metadata and is linked to from the EOS Data Gateway (EDG) when ordering data. The ScienceQualityFlagExplanation is changed in response to analysis and should be checked for updated information. In the MOD29E1D data product, there are four instances of the ScienceQualityFlagExplanation, one for each of the two parameters, sea ice determined by reflectance data and ice surface temperature, in each of the northern and southern grids written in the metadata. See the MODIS Land Quality Assessment Web site for further details.
