Description

Addresses an issue found when loading subsequent days of DMSP SSUSI SDR-Disk data, which caused a memory failure. Fixed by adding a custom concat_data method. This shares many lines of code with TIMED GUVI, so the comment elements were moved to pysatNASA.instruments.methods.jhuapl.

stime = dt.datetime(2010, 4, 14)

ssusi.load(date=stime)  # Will be fine

stime += dt.timedelta(days=1)
ssusi.load(date=stime)  # Will fail and potentially crash your computer without fix
