OLCI support disappeared?
Now, as they said, the GUI hasn't support processing of OLCI. You should process OLCI in command-line mode like its installation.
For example, you can use 'l2gen ifile=xfdumanifest.xm ofile=.....'(see the help of l2gen) in terminal in Linux or Mac OS.

getanc.py is failed for Landsat8 OLI
Dear everyone, A granule of OLI data was downloaded from USGS (new website) named :LC08_L1TP_119038_20170527_20170527_01_RT_MTL.txt. However, I can't download the ancillary files by GUI and getanc.py. The message was:ERROR: For LC08_L1TP_119038_20170527_20170527_01_RT_M...

Batch processing Landsat with l2gen
You can use one programming language(shell or python) to implement a batch processing, for OLI, this task is similar with MODIS. Here is my idea:(1) to put all files into same folder.(2) using a loop statement(do,while, for, etc.) to read filename one by one, then you can use this as input to execut...

How to calculate the transmittance according to the aerosol Luts(dtran_a,dtran_b...)
As the title, I have using the wavelength and view geometry to get the dtran_a and dtran_b, but I don't know how using these data to generate the transmittance. Are there some equations or scripts?

Can't access the website of data processing components by distributed separately
Dear everyone,I remembered the processing component for OLCI (SEN-3A) was separately released as a test version, now I want to use it to process some OCLI data in terminal window. However, I can not access the website of data processing components now(http://oceandata.sci.gsfc.nasa.gov/ocssw/). Was ...

The result of Mosaic is too small generated by gpt.sh
Thanks George, the problem has been solved according to your recommendation. I had thought the pixel resolution was determined automatically like the reprojection tool, but that was wrong. I must assign a fixed value to execute mosaic oration, if not, the default pixel resolution 0.05 would be adopt...

Hi Aynur,The problem has been fixed according to George's recommendation. I thought the pixel resolution was determined automatically according to different sensors(250m,300m,30m etc.) like the reproject operation. Now the mosaic works well. A file including the input file name and parameters fo...
