MOD29PG / MYD29PG sea ice products
The level-2-gridded (L2G) product is the result of mapping all the MOD29 and MYD29 swaths acquired
during day or night to grid cells of a map projection. The projection used for the sea ice products
is the Lambert Azimuthal Equal-Area (polar grids) projection, EASE-Grid. The MOD29PG and MYD29PG
products are necessary intermediate products used as input to the daily sea ice products MOD29P1
and MYD29P1. Separate products are generated for day or night. MOD29PGD (or MYD29PGD) and MOD29P1D
(MYD29P1D) are the day products and contain data acquired in day mode of the MODIS sensor. MOD29PGN
(or MYD29PGN) and MOD29P1N (or MYD29P1N) are the night products and contain data acquired in the
night mode of the MODIS sensors. The MOD29PG and MYD29PG products are not archived at NSIDC and are
not available for order through ECS. Only brief summary descriptions are given for this product because
it is not an orderable product.
The Lambert Azimuthal Equal-Area projection is divided into northern and southern polar
grids. The polar grids are based on the Lambert Azimuthal Equal Area map projection centered on
each pole. The grids are compatible with the NSIDC EASE-Grid. Each grid contains 313 tiles with
each tile covering approximately 10 x 10 degrees.
For a full description of the MOD29PG and MYD29PG products, see the Sea Ice Products User Guide and / or the ATBD.
