error downloading GLOBAL_ANALYSISFORECAST_BGC_001_028

[dancrear]

Hi @pepijn-devries

Apologize for pinging you again here. Looks like there's a strange issue going on when downloading any layers from the product GLOBAL_ANALYSISFORECAST_BGC_001_028. I used the same code framework I have for downloading other physical and biogeochemical products but pretty immediately after the Preparing job... text comes up in the console I receive the error:

Failed to collect information from subset-job. HTTP 400 Bad Request.

I've messed around a lot with years, months, layers, and variables and I get the same error. Below is the code I tried.

cms_download_subset( destination = destination, product = “GLOBAL_ANALYSISFORECAST_BGC_001_028”, layer = "cmems_mod_glo_bgc-pft_anfc_0.25deg_P1D-m", variable = c("chl","phyc"), region = c(-150,-40,-70,40), timerange = c("2022-01-01 UTC", "2022-02-01 UTC"), verticalrange = c(0, -1), overwrite = TRUE)

Thanks again for your help! As you can see I'm trying to use your package to download a lot of different variables so I really appreciate your work on this.

Best, Dan

Hi @dancrear,

Thank you for reporting. I've not figured out yet what is going wrong here exactly. But do note that you can get the available layer names with:

library(CopernicusMarine)

details <- cms_product_details("GLOBAL_ANALYSISFORECAST_BGC_001_028",
                               variant = "detailed-v3")

Showing that cmems_mod_glo_bgc-pft_anfc_0.25deg_P1M-m_202311 is the correct layer name. But even with that name it's still not working. I will have to some more digging and get back to you on that.

Cheers,

Pepijn

Hi @dancrear,

Unfortunately, I'm not able to figure out what is going wrong here. My implementation of the API at https://data-be-prd.marine.copernicus.eu/api/download/ is based on reversed engineering. The API does not give any feedback on why this particular request is not accepted. The documentation of the API is also pretty much non-existing to my knowledge. I will contact the people at Copernicus Marine to see if they are willing to help me out.

Meanwhile, I will also work on implementing subsetting Copernicus Marine data with ZARR (see https://github.com/pepijn-devries/CopernicusMarine/issues/34), but this may take some time.

As a temporary workaround you could either download the complete set with cms_download_stac or use the deprecated copernicus_download_motu method. However, the last option may become defunct in the future.

Any progress on the issue reported here will be posted here...

Cheers,

Pepijn
