How to calculate percentile amount of a range chl value

There is already very good advice from Danny Knowles, but I wanted to mention another approach.  If you have the OCSSW processing system you can use l3bindump with the level-3 binned data to generate ASCII files with binned data values.  You can then use the data with one of the many full-...

no reply to data request

Another user here mentioned that he had not received the email notification.  He did look in the junk and quarantine folders.  He is, however, able to check status online.

Can't Add bathymetry and elevation bands and masks

The SeaDAS 7 GUI is very complex, so takes some time to learn.   Assuming that you are interested in statistics for surface (satellite) chlor_a, you aren't trying to do anything unusual, so you are probably missing a small step that experienced users do without even thinking.  The...

Can't Add bathymetry and elevation bands and masks

You need to provide more details.   What data are you using?   Are you able to create a bathymetry mask for your desired range of depths?  How do you plan to use the mask (e.g., do you want statistics for the chlor_a in the given range of depths)?A common "use case"...

MODIS aqua level 3 chl-a data processing

Giovanni can often provide very quick results, but often has constraints that limit you to suboptimal choices.   A typical use case is to generate a time series for your region of interest to see if there are enough data (think cloud-free areas inthe individual passes) to support the calcu...

OLCI support disappeared?

You will need to compile with a bug fix (OLCI mapping offset) or just wait for the next update.Here too, olci is missing from "Update OC Processors" in the GUI.  It is, however, present (and "works for me") in the command-line:$ install_ocssw.py -hUsage: install_ocssw.py [op...

MODIS aqua level 3 chl-a data processing

As others mentioned, the lack of the OCSSW Processing System on Windows should not be a problem if you are using level-3 mapped files.  The SeaDAS GUI does include the BEAM Graph Processing Facility, which can be used in the GUI but also in command-line (terminal) mode via the Graph Processing ...

By "data name" do you mean file names like A2006167181000.L0?There are GUI programs called download managers that accept a list of URL's, or you can use command-line programs such as wget or curl.  If you just have the file names you can edit the list to add https://oceandata.sci....

l2gen MOD02/MYD02

I think you have seen the "SyntaxError: Missing parentheses in call to 'print'" problem before.   It means a script intended for use with python2 has been run with python3.   The pyverchk.py script was originally written to deal with different python2 versions.&...
