It has been observed that biogenic emissions, such as isoprene (ISOP) and terpene (Terp), exhibit a sudden decrease in concentration as time progresses from 23:00 to 00:00 UTC.

Please see the figures for ISOP on 20230510 at 12z cycle run

  1. Isoprene emissions at 23:00 UTC on May-10-2023: Slide 2

  2. Isoprene emissions at 00:00 UTC on May-11-2023: Slide 3

It seems that we did not see a similar issue at 06z cycle
