Getting M2T1NXAER (MERRA-2 PM_{2.5}) via OPeNDAP

[kodiologist]

Consider this Python script:

Code: Select all

from datetime import datetime
from pydap.client import get_cmr_urls
print(get_cmr_urls(
    doi = '10.5067/KLICLTZ8EM9D',
    time_range = [datetime(2013, 7, 15), datetime(2013, 7, 15)],
    limit = 1000)[0])

It produces the URL:

https://opendap.earthdata.nasa.gov/collections/C1276812830-GES_DISC/granules/M2T1NXAER.5.12.4%3AMERRA2_400.tavg1_2d_aer_Nx.20130715.nc4

But when I visit the URL, I get

Hyrax - Resource Not Found (404)… The specified path 'collections/C1276812830-GES_DISC/granules/M2T1NXAER.5.12.4:MERRA2_400.tavg1_2d_aer_Nx.20130715' does not identify a granule in CMR.

Please let me know if there's some other way to get this dataset (M2T1NXAER) via OPeNDAP, since the service I've been using for the past few years (at https://goldsmr4.gesdisc.eosdis.nasa.gov/opendap/MERRA2/M2T1NXAER.5.12.4 ) has been retired.

Turns out it's just a file-extension thing. If I add another ".nc4", yielding

https://opendap.earthdata.nasa.gov/collections/C1276812830-GES_DISC/granules/M2T1NXAER.5.12.4%3AMERRA2_400.tavg1_2d_aer_Nx.20130715.nc4.nc4

, it works fine.
