In a L2 total columns GEOMS Boulder Lidar NO2 file:

Variables
['ALTITUDE.INSTRUMENT',
 'ANGLE.SOLAR_AZIMUTH',
 'ANGLE.SOLAR_ZENITH.ASTRONOMICAL',
 'DATETIME',
 'DATETIME.START',
 'DATETIME.STOP',
 'INTEGRATION.TIME',
 'LATITUDE.INSTRUMENT',
 'LONGITUDE.INSTRUMENT',
 'NO2.COLUMN_ABSORPTION.SOLAR',
 'NO2.COLUMN_ABSORPTION.SOLAR_AMF',
 'NO2.COLUMN_ABSORPTION.SOLAR_FLAG',
 'NO2.COLUMN_ABSORPTION.SOLAR_UNCERTAINTY.COMBINED.STANDARD',
 'NO2.COLUMN_ABSORPTION.SOLAR_UNCERTAINTY.MIXED.STANDARD',
 'NO2.COLUMN_ABSORPTION.SOLAR_UNCERTAINTY.RANDOM.STANDARD',
 'NO2.COLUMN_ABSORPTION.SOLAR_UNCERTAINTY.SYSTEMATIC.STANDARD',
 'SOURCE.PRODUCT',
 'TEMPERATURE.EFFECTIVE.NO2',
 'TEMPERATURE.EFFECTIVE.NO2_SOURCE',
 'TEMPERATURE.EFFECTIVE.NO2_UNCERTAINTY.COMBINED.STANDARD',
 'TEMPERATURE.EFFECTIVE.NO2_UNCERTAINTY.MIXED.STANDARD',
 'TEMPERATURE.EFFECTIVE.NO2_UNCERTAINTY.RANDOM.STANDARD',
 'TEMPERATURE.EFFECTIVE.NO2_UNCERTAINTY.SYSTEMATIC.STANDARD']

This should be giving the same result as the xarray method

groundbased_lidar.o3_noaa.csl001_hires_guilford.ycfs.ct_20230814t132136z_20230815t040136z_002.hdf

is the one I was testing that had a 39-char string with no other dims

@btang1 were you able to test this on all the TOLNet files in your period, make sure they read properly (and without error)?
