Using:
GDAL 3.12.0 "Chicoutimi", released 2025/11/03
The following returns almost immediately, if you know the band number.
Unfortunately, with this data set, the bands and arrays aren't
consistent across model runs, so I can't rely on a fixed band. A
grib2.idx does exist on S3 (which is why using band works so fast):
gdal raster select -i
/vsis3/noaa-nbm-para-pds/blend.20251104/01/core/blend.t01z.core.f059.co.grib2
-o blend.t01z.core.f059.co.tif --band 132 --co COMPRESS=DEFLATE --overwrite
The following takes over 4 minutes to complete. Downloading the file
locally only takes about 20 seconds.
time gdal mdim convert -i
/vsis3/noaa-nbm-para-pds/blend.20251104/01/core/blend.t01z.core.f059.co.grib2
-o blend.t01z.core.f059.co.tif --array "QPF06_0-SFC" --co
COMPRESS=DEFLATE --overwrite
If I download the file first, so it's local, then it completes immediately.
Any thoughts on speeding this up? Ideally, I don't want to download the
file first.
Thanks!
Scott
