Hi François, hi everyone, I am trying to apply the GSW landmask to MSI scenes with the command below with polymer-4.17beta2 but I see no difference with the scene I process without using the GSW landmask. The GSW netcdf are downloaded in the correct directory and I get no error when the image is pro...

Hello Nathan,
Is it possible to have access to this release quickly?
I am having the same problem to process near real time data and need to fix it as soon as possible to send data for two cruises currently at sea.

Hello François, I have modified ./polymer/level1_nasa.py and ./polymer/params to add VIIRS-JPSS2 tau_r, K_O2, and K_NO2 (from NASA-OceanColor website: https://oceancolor.gsfc.nasa.gov/resources/docs/rsr_tables/ ) and add support for VIIRS-JPSS2 in POLYMER, it seems to work well. It would be great to...

Hello, To my understanding, polymer does not correct for stripping but you can try a de-striping algorithm: https://opg.optica.org/oe/fulltext.cfm?uri=oe-22-23-28058&id=303697 I have personally never tried using this type of correction but according to the example presented in the paper, it should w...

Hi François, Thank you I managed to get nLw from Rw and the extraterrestrial solar flux. I am now trying to get Ed(0-). I would need to account for tau_rayleigh, tau_gases and tau_aerosol to attenuate F0 through the atmosphere. I believe I can get tau_rayleigh from the surface pressure (sp), and tau...

Hi François, Sorry I was at sea for a while. I was indeed using the argument "directory" to the class Ancillary_NASA but it wasn't working. It was still downloading the ancillary data without crashing but it was creating the usual folder with the year number and Julian day. The error happened later ...

Hi François, I am processing MODIS, VIIRS and OLCI using NASA and ERA5 ancillary data. I can't make polymer download and use the ancillary data from a custom ancillary folder that I define when I process NASA satellites. It works perfectly with ERA5 though... I have installed polymer 4.14 Best, Guil...

Hi all,
Is there any way to output nLw using POLYMER?
Best,

Hi François, I may have found the problem. I am only processing the zone of interest of the L1A file into L1C using the same sline, eline, srow and erow on l2gen. The output file are usually ~600K except the ones that make the ancillary request crash on POLYMER. Those ones are ~200K so the zone I am...

I have set my program to create an ancillary folder for each image separately and found out that polymer is creating a folder dated to 1970/01/01 ANCILLARY/ERA5/A2017315041000/1970/01/01/ for all the image the cdapi can't find ancillary data for: A2017315041000/ A2018035061500/ A2018043052500/ A2018...
