MODIS/Terra Aerosol 5-Min L2 Swath 10km - NRT

The new Collection 6.1 (C61) MOD04_L2 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.

新版集合6.1（C61）MOD04_L2产品是基于对城市区域暗目标（DT）气溶胶反演算法的改进以及深蓝（DB）气溶胶反演的不确定性估计而推出的升级版本。MODIS二级大气气溶胶产品提供了全球范围内海洋和陆地上的环境气溶胶光学特性、质量保证以及其他参数的检索结果。在集合5以及更早的集合中，仅存在一个10公里（正对视场）空间分辨率的气溶胶产品（MOD04_L2）。自C6版本起，暗目标（DT）气溶胶算法团队提供了一种新的3公里空间分辨率产品（MOD04_3k），旨在服务于空气质量领域。欲了解更多信息，请访问MODIS大气网站：
