Where can I pull Daymet data ? Opendap or Thredds?

[kpuln]

In the past, I've been able to download Daymet data from the following:
- https://www.earthdata.nasa.gov/data/catalog/ornl-cloud-daymet-daily-v4r1-2129-4.1

... and then:
- https://opendap.earthdata.nasa.gov/thredds/catalog/ornldaac/2129/tiles/catalog.html

Unfortunately, the above URL is no longer available and suggests that the data has moved to on of the Thredds cloud servers. After registering with https://urs.earthdata.nasa.gov/, it seems that the https://thredds.daac.ornl.gov server redirects back to the Opendap servers.

My thoughts are that the new URL would be: https://thredds.daac.ornl.gov/thredds/catalog/ornldaac/2129/tiles/
but that is not the case.

Can anyone advise and point me in the right direction..?

Also, when I last checked, the data catalog contained data up to 2024, what I'd like to do is download any of the 2025 available data.

Thank you in advance,

KP

Hello kpuln,
Thank you for your interest in the Daymet dataset. Daymet access tools and services have been updated. Here is a list of current access methods for Daymet daily data files:

AppEEARS : https://appeears.earthdatacloud.nasa.gov/

Daymet Single Pixel Extraction Tool: https://daymet.ornl.gov/single-pixel/

Earthdata Search Direct Download : https://search.earthdata.nasa.gov/search?q=Daymet_Daily_V4R1_2129&ac=true

OPeNDAP : https://opendap.earthdata.nasa.gov/collections/C2532426483-ORNL_CLOUD/granules/Daymet_Daily_V4R1.daymet_v4_daily_na_tmax_2023.nc.dmr

OPeNDAP URL with indexing subset:
https://opendap.earthdata.nasa.gov/collections/C2532426483-ORNL_CLOUD/granules/Daymet_Daily_V4R1.daymet_v4_daily_na_tmin_2024.nc.dap.nc4?dap4.ce=/y[5000:1:6000];/x[4000:1:5000];/tmin[0:1:0][5000:1:6000][4000:1:5000]
Keep in mind that Daymet is projected and OPeNDAP works on index ranges.

I hope this is helpful. Let me know if you have any questions.
Best wishes,
Michele
