Dear Norman,Many thanks for the helpful information.I just have a small thing to clarify .MERIS data is in '*.bz2' compressed format. By checking a few days I get the following resultMERIS=====  Year: 2007 | Day: 123 | Date: 2007-05-03 00:00:00 | TotalSize (GiB): 1.1766   Year: 200...

I am sorry to ask this question, but I found no better place to ask.I would very much appreciate if anyone could help me get a sense of the estimate of 1 day level 2 data size globally.I ask this because I am interested in looking at the coastal regions globally using the best available pixel resolu...

Many thanks Don,I think I now have the OCSSW up and running.Just tested the SST file and worked fine as shown in the report below.Will now run the other exercises in the cookbook to familiarize with the command line. l2bin 5.0.0 (Aug 16 2019 12:47:25)Loading default parameters from /home/eligio/ocss...

Thank you Sean and George for your reply.Thanks for providing the new file name. It helps keeping consistent with the example as I initially planned to do so.After your advises, I run l2bin for my nighttime SST reversing the flag and for the daytime SST with the original setting.Both options give me...

Hi folks,This may be a simple question but, I am trying to get started with ocssw command line data processing.For now, final goal is to be able to generate composites (temporal) using l3bin. As I never used these command line tools before, I started with examples provided in this post https://seada...

The authentication has brought a lot of issues and I struggled for a day :cry:. After many trials with the examples provided https://oceancolor.gsfc.nasa.gov/data/download_methods/, I was able to download on windows machine using session cookiesIt seems that wget fails without the "--auth-no-ch...

I think I got the answer.
The spline was smoothing the output :grin:

Hi folks,I came across the issue of having to calculate the lon/lat based on Number of Scan Lines, Pixels per Scan Line, etc.This is the first time I encounter such issue while working with L2 MERIS data. To calculate the lon/lat I followed this post https://oceancolor.gsfc.nasa.gov/forum/oceancolor...

Thank you folks,
I start to get the point. I may look at some of your suggestions.
The SMI I used is monthly "A*L3m_MO_CHL_chlor_a_4km.nc" provided in this website.
And yes, it does not come with counts, I calculated those myself.
Again thanks for your clarification

Thanks for the background information.But I still have cannot fully understand why I am getting the lines.From the explanation I get the sense that the horizontal lines are caused by the difference between l3bin and l3m?Then, not appropriate means l3m should not be used for any statistics as I got t...
