Thanks for looking into this @afriesz! Are you accessing OPeNDAP programmatically or through the interface? I am getting this result for accessing OPeNDAP programmatically (python3, using the requests package), through the web interface, or by pasting the URL into my browser. what metadata fields ar...

Hello, Have the global attributes changed for OPeNDAP MODIS data downloads? On 6 June 2024, downloading the below URL gave me a netCDF file with 200 global attribute fields; of these 195 begin with CoreMetadata or ArchiveMetadata. Today the same URL gives me a netCDF file with 5 global attributes fi...

ok, thanks for looking into it, Brett!

OK, on further consideration this makes more sense to me. I did not notice that the HDF file does not include the longitude/latitude coordinate values. The netCDF file includes lon and lat as 4800x4800 64-bit floating point netCDF variables, which comes out to 175 MB each just for lon and lat. If I ...

Hello, I'm seeking to calculate land surface water index (LSWI) to use alongside the M*D13Q1.061 250m EVI values. LSWI is calculated as (NIR - SWIR) / (NIR + SWIR); in terms of MODIS bands: (band 2 - band 6) / (band 2 + band 6). I can get 250m band 1, 2, 3, and 7 values from M*D13Q1.061, but I'm onl...

Hello, I'm using OPenDAP to retrieve netCDF files for a subset of layers in MOD13Q1.061. I'm noticing that my netCDF files containing 3 layers are larger than the original HDF files containing 11 layers. I suspect this is because hyrax is converting HDF short types to netCDF float types. Is this exp...

I'm trying to download MOD13Q1.061 data for several tiles from the LPDAAC opendap server. I'm getting a lot of 400 errors trying to adapt the opendap quick start guide (https://opendap.github.io/documentation/QuickStart.html) to my situation. I can access the html forms at the data URLs (for example...
