MOD29 / MYD29 sea ice products
These products are generated using the MODIS sensor radiance data product (MOD021KM and MYD021KM), the
geolocation product (MOD03 and MYD03), and the cloud mask product (MOD35_L2 and MYD35_L2). The output file
contains sea ice extent scientific data sets (SDS), ice surface temperature SDS, quality assurance (QA)
SDSs, latitude and longitude SDSs, local attributes, and global attributes. The sea ice extent algorithm
identifies sea ice-covered oceans by reflectance characteristics; it also estimates ice surface temperature
for complete global coverage; a MOD29 sea ice product would be generated for all swaths acquired during a
day. The Terra sea ice surface temperature data product is validated (stage 2) for the cold season. Aqua
sea ice data products are provisional.
See the validation webpage for further details and
validation definitions.
