Product Description:
MODATML2 and MYDATML2 contains a combination of key high interest science parameters. The ATML2 product provides a subset of datasets from the suite of MODIS Atmosphere team products on both 5km scale (native 5 km cloud properties and a 5x5 pixel sample of the 1km cloud datasets) and a 10 km scale (aerosols). The sampling of 1 km datasets is consistent with the team's L3 algorithm (using the pixel 4, 9 in the along-track direction for each 10 km scan in order to avoid contiguous dead 500 m band 6 pixels on the Terra instrument.

C6 significantly increases the number of datasets included in the ATML2 product, including the full suite of QA datasets. Since the ATML2 data granule file size is significantly smaller than the combined size of the individual L2 products, and because the 1 km pixel sampling is consistent with the L3 algorithm, the ATML2 product is a more practical means for the user community to develop research L3 algorithms for their own specific purposes.

When Using Collection 6.0 Data:  Collection 006 (C6)

To determine the Collection version of the data you used or are using, look at the HDF filename. If there is a ".006." field in the HDF filename, then it's Collection 6.0 data.
