ACORN - Aggregating SAG wave delayed mode collection

[ggalibert]

The portal fails to aggregate the whole collection of ACORN wave data from SAG because of a change in the grid of the NetCDF files.

Until 2011-04-01 00:30:00 UTC (included) latitude is defined as follow:

The grid has slightly changed and LATITUDE is ordered increasingly as opposed to decreasingly before.

[ggalibert]

Files covering the period 2011-04-01 01:30 to 2018-09-30 (end) were produced first in 2017-12, while the files covering the period 2009-12-02 (start) to 2011-04-01 00:30 were produced in 2018-02.

The period 2011-04-01 01:30 to 2018-09-30 (end) might need to be re-processed on the same grid as the one used for the more recently produced files.

[scosoli]

will check what has happened with the grid. I have not changed it as far as I am aware but something may have happened when transitioning to a new processing machine. what priority has to you this modifiction? we're all quite busy until December 14

[ggalibert]

@scosoli no worries this can be low priority and will be kept open here until you have time to look at this.

[ggalibert]

@yashahoo please have a look.

[yashahoo]

I believe I started processing these 2017q4, so I am using Simon's more recent grid files. Once we figure out the problem I will re-process the early years with new grid.

[lbesnard]

@yashahoo I'm trying to follow up on this. Has any data been reprocessed on your side to fix this issue?

[yashahoo]

Yes, this remains on the low priority to do list as it is a substantial task and the underlying data are still good (ie there is nothing wrong with the individual files). Myself or @scosoli will complete this as soon as possible.

[lbesnard]

thanks a lot! FYI, I created an "acorn" label to make it easier to find issues related to your facility.
Feel free to close the ones which can be:
