Re: [las_users] Re: Parsing download link from JSON Response

Actually, I misspoke previously. The JSON response does appear to contain the URL, though where it's located can depend on the how the data set is configured.

In the example above (https://paste.apache.org/kl1J), the LAS ID and data access URL are highlighted below.

{
"datasets": {
"dataset": [
{
"name": "RSS SMAP Level 3 Sea Surface Salinity Standard Mapped Image Monthly V2.0 Validated Dataset",
"ID": "SMAP_RSS_L3_SSS_SMI_MONTHLY_V2",
"doc": "https://podaac.jpl.nasa.gov/dataset/SMAP_RSS_L3_SSS_SMI_MONTHLY_V2",
"catid": "SMAP_RSS_L3_SSS_SMI_MONTHLY_V2",
"url": "http://thredds.jpl.nasa.gov/thredds/dodsC/ncml_aggregation/SalinityDensity/smap/aggregate__SMAP_RSS_L3_SSS_SMI_MONTHLY_V2.ncml",

It's also possible that the data access URL will be under each "variable" in the above JSON.

I'm going to repeat what I've hinted at in previous correspondence. This is an unsupported API. We don't use it internally. There's likely a better way to programatically access these data.

In particular, parsing this catalog XML (https://thredds.jpl.nasa.gov/thredds/catalog.xml) might a better approach.

Hi Roland,
Can you explain to me how as a start I can retrieve, for example, a list of LAS ID's for any data sets in the system?
Basically, My aim is to create a Python API for programmatic access to Level 3 datasets containing within the PO.DAAC LAS instance.
Again, thanks for any advice you can throw my way.

The location of the data is not visible to the client in this API. The API is designed to allow the user to find the names (for display to the user) and LAS ID (for making requests) of the data sets in the system and then to use the other parts of the API to understand the products (mostly plot images, but some data representations) that are available. And finally to request a product be made for the client.

If you are just looking for a wholesale way to get the data and download it you're better off looking at an source and API designed for that purpose. Find a THREDDS catalog that contains the data in question or even an FTP site is likely to be more productive.

Hi Folks,
I am currently attempting to obtain dataset download link(s) from the 'getDatasets' [0] call to the LAS which resides at NASA JPL's PO.DAAC [1].
I'm providing part of the JSON response, which represents one record, from the getDatasets operation at [2], if someone could take a look and point out to me the dataset download link(s) it would be highly appreciated.
Thanks in advance.
