First, I downloaded AQUA_MODIS.20170123T193500.L2.OC.nc, and the metadata shows north=39 south=18 west=-110 east=-81, so your subset area north=23.5 south=22 west=113 east=114.5 has no intersection with the source product's boundary. Secondly, you need to provide the absolute path of the files for t...

If your task is to Subset and Reprojection, you can avoid Mosaic by extract (SeaDAS processors) and then reprojection -- 1. SeaDAS-Toolbox -> SeaDAS Processors -> extractors 2. Raster -> Geometric -> Reprojection Here is the resulted image of chlor_a Screen Shot 2023-05-08 at 11.44.03 AM.png --

Actually, T2001228173000.L1A_LAC has 17:31:45 as start time (RANGEBEGINNINGTIME= 17:31:44.786658), therefore the corresponding GEO file is TERRA_MODIS.20010816T173146.GEO.hdf, which has the same start time (perhaps 1 second off). Here is the OBPG File Naming Convention -- https://oceancolor.gsfc.nas...
