Not able to download data from webpage

by prec8ase » Mon May 09, 2022 9:26 am America/New_York

I am trying to use the service and have selected some data to download. I have been able to select the data I need. Unfortunately I keep getting an error when I try to log in to download the data via the following link https://oceandata.sci.gsfc.nasa.gov/odps/orders/.

The error says ERROR - Ocean Biology Distributed Active Archive Cebtre (OB.DAAC) We are sorry, but and error has occurred. Please use the back button to return to the previous page. See attachment.

I am using a chrome browser on Win 11 installation

Hi,

What data are you looking for? If you have an order, you have to first login to the OceanColor site to view your specific orders. Navigate to SERVICES > Data Dashboard on the navigation bar. Use the login button the right of the navbar to login to your Earthdata login account. Then click the Orders > View Active button on the page.

If you have an order you are saying you can't access, please provide the order number so we can help investigate.

Hi,

I am also unable to download chlorophyll data using Python's request module because the https link does not work. I get the same error message as the screenshot posted above. I have found that the https links to download SST data do work; however, the link to download chlorophyll data does not work.

I tried two links, both of which give the same error:
https://oceandata.sci.gsfc.nasa.gov/opendap/VIIRS/L3SMI/2020/001/V2020001.L3m_DAY_SNPP_CHL_chlor_a_9km.nc
https://oceandata.sci.gsfc.nasa.gov/ob/getfile/V20200101.L3m_DAY_SNPP_CHL_chlor_a_9km.nc

@kwentz10 Thank you for the links you tried. For the python script please use the second example of your links to .../ob/getfile/filename
The link you have has an extra digit. Filename format should be yeardoy where you have yearmonthday, so for day-of-year 10 (jan 10) use this:
https://oceandata.sci.gsfc.nasa.gov/ob/getfile/V2020010.L3m_DAY_SNPP_CHL_chlor_a_9km.nc
not this:
https://oceandata.sci.gsfc.nasa.gov/ob/getfile/V20200101.L3m_DAY_SNPP_CHL_chlor_a_9km.nc

If you'd like to use opendap, you can go directly there to that URL the data https://oceandata.sci.gsfc.nasa.gov/opendap/VIIRS/L3SMI/2020/001/V2020001.L3m_DAY_SNPP_CHL_chlor_a_9km.nc.dmr.html and choose the format in which you'd like to download the file.
