Re: Evaluating height of trees with high precision for different year

You may find this ICESat-2 data product useful, for both terrain and canopy heights from a satellite laser altimeter: https://nsidc.org/data/atl08/versions/6 The vertical precision is likely sufficient. The coverage over your area of interest might not be dense enough, depending upon your applicatio...

Re: no VersionID in ATL15 Metadata

Hi Jessica, Thanks for pointing this out! I contacted the ICESat-2 Project Science Office and this attribute should be populated with the most recent Version number, but a blip in the QA process missed it this go around. Just a heads up, ATL14 v003 and ATL11 v006 have similar issues. This will be fi...

Re: Migrating from legacy token to NASA EarthData token to download ATL03 from NSIDC

Dear Eduard, Thank you for reaching out on the Earthdata Forum. Bearer tokens work a little bit differently than echo tokens did. This format should work for curl: curl -b ~/.urs_cookies -c ~/.urs_cookies -O -J -L -H "Authorization: Bearer <your token>" --dump-header response_header.txt &q...

Re: ICESat-2 download_granules(path) stuck on pending

Hi Ty,

Nice to chat with you today. As I mentioned, but just to document here, I'm guessing your initial order was made during some scheduled maintenance downtime on Wednesday. Glad to hear your order went through eventually.

Kind regards,

Mikala

Dear Yu-Feng,

Does it work to add -r (for downloading recursively) to either the wget or wget2 commands?

Re: 401 Unauthorized in [https://n5eil01u.ecs.nsidc.org/ATLAS/ATL03.005/] using Wget2

Hello again,

Have you tried a test with wget recently? The operations team hasn't made any changes to block your IP address. They are wondering if it's something with wget2.

Let me know if you can successfully use wget for a test granule.

P.S. We did experience a temporary outage on n5eil01u last night and earlier today that may have contributed to your "refused to connect" error early this morning.

Dear Yu-Feng, Apologies, I don't fully understand your last message. Our operations staff believe you will have better luck with your "refuse to connect" error, if you attempt your wget2 access using a bearer token. You can generate a bearer token from your Earthdata Login profile at urs.e...

Re: 401 Unauthorized in [https://n5eil01u.ecs.nsidc.org/ATLAS/ATL03.005/] using Wget2

Dear Yu-Feng, We recommend you try going to your EDL profile and generating a bearer token: urs.earthdata.nasa.gov -> "Generate Token" Then, add that to your wget2 command as: wget2 --header='Authorization: Bearer TOKEN_HERE' and remove the --http-user=yufengho --ask-password parameters. L...
