MOD10_L2G / MYD10_L2G snow products
The L2G products are the result of mapping all the MOD10_L2 and MYD10_L2 swaths acquired during a day to grid cells of a map projection. The projection used for the snow cover products is the sinusoidal projection. The MOD10_L2G and MYD10_L2G products are a necessary intermediate product used as input to the daily snow cover products MOD10A1 and MYD10A1. The MOD10_L2G and MYD10_L2G products are not archived at the DAAC and are not available for order through ECS.
The MODIS Land Science Team recently changed the MOD10A1/MYD10A1 and MOD10A2/MYD10A2 grids from the Integerized Sinusoidal (ISIN) grid to a standard sinusoidal grid. This change coincided with the MODIS data products Version 4 algorithms, the processing and reprocessing of data into MODIS Terra Version 4 data products, and the release of the MODIS Aqua Version 3 data products. The main advantages of the sinusoidal grid include improved vendor support and less distortion at the pixel level (no brick-like shifts between rows). The sinusoidal grid also resolves problems with nesting between products with different resolutions.
