<p>Michael,</p>
<p>This is both a usage issue, and the driver not erroring out on
that invalid use whereas it should.<br>
</p>
<p>You should prefix the URL with /vsicurl/ , and if you use Bash as
a shell, to make sure the double quotes are preserved up to GDAL,
you need to surround the whole string with single quote
characters.</p>
<p>So:<br>
</p>
<p>gdalmdiminfo 'ZARR:"<a href="https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr" target="_blank" rel="noreferrer">/vsicurl/https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr</a>"'</p>
<p>and similarly for gdalinfo:</p>
<p>gdalinfo
'ZARR:"/vsicurl/<a href="https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr" target="_blank" rel="noreferrer">https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr</a>"'</p>
<p>gdalinfo
'ZARR:"/vsicurl/<a href="https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr" target="_blank" rel="noreferrer">https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr</a>":/precip:0'
(0 here for the 2D slice at time index = 0)<br>
<br>
</p>
<p>In <a href="https://github.com/OSGeo/gdal/pull/6330" target="_blank" rel="noreferrer">https://github.com/OSGeo/gdal/pull/6330</a>, I've improved doc and
error messages.</p>
<p>Even<br>

<div>That group error makes me think there's a kind of nested
dataset issue to navigate? But I can't see how zarr or gdal
would expose those? There is a variable called 'precip'. </div>

</div>
<div>I'm comparing to the python in this notebook, which works
fine on the same system. I'm using GDAL built from source. </div>
