Terra Product Descriptions: MOD04_3K

Last update: August 15, 2017

Data Set Short Name:
MOD04_3K

Data Set Long Name:
MODIS/Terra Aerosol 5 Min L2 Swath 3km

Platform:
Terra

Instrument:
MODIS

Product Description:
The new Collection 6.1 (C61) MYD04_3K product is an improved version based on algorithm changes in Dark Target (DT) Aerosol retrieval over urban areas and uncertainty estimates for Deep Blue (DB) Aerosol retrievals. The MODIS level-2 atmospheric aerosol product provides retrieved ambient aerosol optical properties, quality assurance, and other parameters, globally over ocean and land. In Collection 5, and earlier collections, there was only one aerosol product (MOD04_L2) at 10km (at nadir) spatial resolution. Starting from C6, the Dark Target (DT) Aerosol algorithm team provided a new 3 km spatial resolution product (MOD04_3k) intended for the air quality community.

The 3 km product MOD04_3k differs from the original 10 km product MOD04_L2 only in the manner in which reflectance pixels are ingested organized and selected by the aerosol algorithm. Overall the 3 km product closely mirrors the 10 km product.
