3 – merged Mission-merged: Full mission of level 3 data in one file. Three different bin sizes available (0.02, 0.1, 1.0 nm). Available next day.  same as level 3 Browse directory
0C – SAM Space Weather: SAM 5-minute irradiance peak and centroid locations. 4 minute latency. Currently in beta phase. An additional 1-minute file is being produced daily. 0.1-7 nm Latest 5-minute file, Browse 5-minute directory, Browse 1-minute directory

Note that due to unexpected rapid degradation, MEGS-B (and consequently MEGS-P) have limited daily exposure. Solar measurements for MEGS-B are made 5 minutes each hour plus one 3-hour period each day.
