Re: Some OLCI results show strange invalid patterns

Hi Martin, Thanks for your feedback. This kind of patterns is typically due to un unstability of the algorithm. Polymer uses the result of previous pixel to initialize the minimization of current pixel, which can lead to successive (vertically) bad pixels within a processing block (which is a horizo...

Re: polymer 4.12 throws ValueError "masked arrays not supported"

Hi Martin, Thanks for the detailed report ! Indeed there is a bug, external ancillary data can not be applied to OLCI due to the NetCDF library returning masked arrays. This can be fixed with the following patch : diff --git a/polymer/level1_olci.py b/polymer/level1_olci.py index 10a4a63..55787d6 10...

Re: Sentinel 2 - missing 4 bands

Dear Federica, Indeed these bands are not included by default. To include band 842, pass the following argument to run_atm_corr : run_atm_corr(..., bands_rw=[443,490,560,665,705,740,783,842,865, 1610, ]) I will make it default in the next polymer release. You could do the same for the other bands, b...

Re: Processing data for particular lat long

Dear Karthick,

Indeed, all Level1 readers support the following keywords: sline, eline, scol and ecol.

Example:

Code: Select all

run_atm_corr(
    Level1_OLCI(product_name, sline=1000, eline=1100, scol=300, ecol=400),
    Level2_NETCDF()
)
Cheers,
François

Re: error to run POLYMER v4.11

Re: error to run POLYMER v4.11

Please edit your file /home/laura/.bashrc, and see if the variable PROJ_LIB is set in this file. If this is the case, please comment out this line, restart your terminal and see if it works.

Re: Compiling cuda binaries

Dear Clémence, Concerning pycuda installation we are internally using either pip install pycuda or https://anaconda.org/lukepfister/pycuda. Also, please make sure to use latest version 0.9.2 which ships with source code instead of compiled binaries : it easens significantly the flexibility of the in...
