How to display the OSCAR 2.0 currents data?
Closed this issue · 2 comments
Hi,
I tried to display the OSCAR 2.0 currents data with the code from this repo.
I downloaded the currents data from https://podaac.jpl.nasa.gov/dataset/OSCAR_L4_OC_NRT_V2.0, convert it to json using the command grib2json -d -c -n -o 20240425-surface-currents-oscar-0.25.json oscar_currents_nrt_20240425.nc, and put it into the public/data/oscar directory. It turned out that no color, and strange currents display.
It was clearly that something was wrong. I read the news at https://nullschool.beehiiv.com/p/welcome-plus-an-update-on-ocean-currents, but did not know how to modify the code to support the column-major ordering of OSCAR 2.0 data.
Could you please give some hint or example about how to change the code to support OSCAR 2.0 currents data?
Thanks!
Yes, this is the same table ordering problem I ran into. My suggestion would be to write a small program that rewrites the JSON file with the data array switched from row-major to column-major. That's easier than modifying the grib2json code.
