MISR Level 3 Aerosol (MIL3MAEN) data files empty?
Posted: Fri Mar 05, 2021 8:01 pm America/New_York
I'm trying to analyze MISR Level 3 aerosol data (MIL3MAEN) for 2015-2020. It looks like the data for 2015-mid2017 comes with two file types:
(a) MISR_AM1_CGAS_0_5_DEG_MMM_YYYY_F08_0031.nc
and
(b) MISR_AM1_CGAS_MMM_YYYY_F15_0032.nc
From mid-2017 onwards, only the latter (b) are available. But the (b) file type does not seem to contain any data variables? For example, in python:
>> from netCDF4 import Dataset
>> nc = Dataset(MISR_AM1_CGAS_JAN_2015_F15_0032.nc)
>> print(nc.variables)
returns {} (an empty dictionary). And comparing the file sizes, type (a) are ~900Mb whereas type (b) are only ~50Mb. Is the data missing? or is there a different dataset, other than MIL3MAEN, that I should be using?
Thanks!
