GPM-IMERG-hhr files on Planetary Computer #2

Open oliviercics opened 2 years ago

oliviercics commented 2 years ago

Hi,

I am using the GPM-IMERG-hhr files available on the Planetary Computer.

Does anybody know,

  1. What is the IMERG-hhr version available in the Planetary Computer ? Is it the EARLY RUN, the LATE RUN, or the FINAL RUN? Is it version 6 ?

  2. The IMERG-hhr data available on the Planetary Computer are for the period 06/01/2000 – 05/31/2021. Are there any plans or possibilities to routinely update the dataset to more recent dates?

  3. Are there any plans to have other versions (LATE RUN, FINAL RUN) available on the Planetary Computer?

Thanks.

Thanks @oliviercics.

  1. I believe that this the "FINAL" run. In an earlier comment, @sharkinsspatial pointed to https://github.com/pangeo-forge/gpm-imerge-hhr-feedstock/blob/main/feedstock/recipe.py#L13-L14. I'll get this added to the collection description.
  2. Updates are somewhat blocked by https://github.com/pangeo-forge/pangeo-forge-recipes/issues/37. We could perhaps implement a workaround to manually update things, but I'd prefer to do this properly by fixing https://github.com/pangeo-forge/pangeo-forge-recipes/issues/37 (cc @rabernat for awareness)
  3. https://github.com/microsoft/PlanetaryComputer/discussions/29 is a request for adding Late and Early as well, if you want to upvote that. https://github.com/microsoft/PlanetaryComputer/discussions/29#discussioncomment-2104392 has a bit of discussion the relative benefits of early, late, and final.

Thanks Tom.

  1. Thanks for the confirmation, that the version is the Final Run.
  2. That would work.
  3. For our use case, we will be using IMERG Late as soon as made available by NASA (within 12-hr) and replace them by IMERG Final once created (3 to 4 months to the current date). That would be for the routine near-real time routine operation (for testing and evaluation purposes we might want to compare full runs with IMERG Late and IMERG Final alternatively)
