Hello,

I wanted to know how I can obtain level 3 and level 4 globally gridded datasets. I would be glad if someone could help me.

Thanks,

Hi Folks,

Specifically we are looking for lv3 or lv4 PO.DAAC Datasets as we wish to use the data within Apache Open Climate Workbench (OCW) [0]. OCW requires input data to be gridded as it provides functions to work with climate models and undertake rebinning, metrics computation and visualization.

I thought there used to be a list of lv3 and lv4 PO.DAAC datasets which one could then retrieve granules for through the WebServices API? Is this still the case? If not, is there another suggested way in which we can obtain such datasets?

Thanks
Lewis

Thanks for the inquiry.

Besides you can retrieve granule files for L3 and L4 using PODAAC web services, you can use ftp or OPeNDAP tools. There are three posts in the Data Recipes Forum that show you how to use the python to download and even to subset the data files.

Here is the links:

    [1] How to batch download data files in a given time range
    [2] Using Python to subset large gridded datasets (v2)
    [3] Using Python and OPeNDAP to subset large gridded datasets

Hope this helps.

Thanks v much for the insight. @omkar, please investigate the commentary closely as this is your next deliverable for the podaac data source in OCW ok.
Thanks everyone
