Correction: Jin et al. Influence of the Nocturnal Effect on the Estimated Global CO 2 Flux. Remote Sens. 2022, 14 , 3192.

If the CO SB 2 sb flux is negative, it means that CO SB 2 sb enters the ocean from the atmosphere, i.e., the ocean is the sink of CO SB 2 sb **. The added sentence is: **If the CO SB 2 sb flux is positive, it means that CO SB 2 sb enters the atmosphere from the ocean, i.e., the ocean is the source of CO SB 2 sb . We want to add the following two sentences on CO SB 2 sb source and sink to **Introduction**, **Paragraph 2**, after the phrase: **At present, the sea-air CO SB 2 sb flux can be measured directly using the eddy correlation method.
