Hi François, It seems cdapi in polymer can't find any ancillary data on ERA5 for some NASA satellites in some rare cases: MODISA: 8 out of 931 images MODIST: 4 out of 985 images VIIRSN: 8 of 1165 images VIIRSJ1: 3 of 431 images I am subsetting each image to only process a 20x20 pixels zone to save c...

Great! I will test it, thank you,
Guillaume

Hello François, Yes I think this is because there is no ancillary available. Do you know what is the delay for ERA5? I managed to get it working with NASA ancillary data with a 3 days delay, but there is several images every day that are not processed due to inconsistent ancillary data (which doesn'...

Hello François, I am trying to process data from several satellites in near real-time. You said in a previous post that the ancillary data from ERA5 is more reliable when I had issues running polymer using the NASA ancillary data. Polymer is indeed running smoothly on thousands of images using ERA5 ...

I was already using a function that processes single files but you were right it was due to garbage references I was creating doing my subsets. Solved now thank you!
Cheers,

Hello François, I get an error when I try to batch process thousands of images, subsetting them beforehand. There number of files opened reaches the limit set for the operating system (which is currently 1024). I will increase it to 4096 to see what it does but I was wondering in the meantime, if th...

Hi François, Sorry for the late answer I was busy on other things. I was trying to process several images, here are few examples that failed when trying to download ancillary data: A2018051010500.L1C_LAC_OC.nc A2016161013500.L1C_LAC_OC.nc A2016074013500.L1C_LAC_OC.nc T2018144223500.L1C_LAC_OC.nc T20...

Hi Francois, I have the same problem downloading ancillary data. It happens with several types of ancillary data depending the image: Trying to download https://oceandata.sci.gsfc.nasa.gov/cgi/getfile/S19700010000123_TOVS.OZONE ... https://oceandata.sci.gsfc.nasa.gov/ob/getfile/S19700010000123_TOVS....

Hi François, As I said before some of my L1C images were corrupted and I could reprocess some, but there is still about 10% of VIIRS and MODIST images that are giving me another error. Here an example with a VIIRS-SNPP image: Starting processing at 2021-02-16 16:09:16.426121 Initializing output file...

I think I found the problem, some of my L1C files are corrupted, even though I could read them without problem with matlab ...
