How to Correctly Select an L2 Scenes to Generate an L3 Image?

I encountered a problem while generating L3 images from MODIS-Aqua L2 images. Suppose I want to generate an L3 image for July 1, 2018. My approach was to aggregate all L2 images from the time period between July 1, 2018, 00:00:00 Z and July 1, 2018, 23:59:59 Z into a single L3 image. However, after ...
